Wastewater and Sewage Microorganism – 3 Parasites Incidental to Wastewater and Sewage Disinfection

Schistosoma mekongi

Image via Wikipedia

Various  spherical worms parasites and flatworms can be transmitted to humans by means of ingesting contaminated water. A single mature larva (or fertilized eggs) can lead to infection and these parasites are relatively durable.

To keep away from the condition due to schistosome, the drinking water might be saved for forty eight hours and as a result rendered safe. Slow sand filters can eliminate the greater part of cercariae (if appropriately operated) and disinfection with residual chlorine of .5 mg/l for one hour will destroy cercariae of the human schistosomes. We recommend chlorination in any event.

A sounder strategy is to get rid of host snails which are inclined to fecal contamination and to other microorganisms in wastewater. The grandmother’s strategy of boiling and filtering will usually function in opposition to contaminating wastewater microorganism species.

Rotifiers

Rotifers are multicellular animals that can take in small particulates as effectively as bacteria and algae between other sewage microorganism species. The rotifers can attach themselves to flock particles and graze on the bacteria on the flock surface. Due to the fact of their significant measurement, protozoa and rotifers and related microbes in wastewater are very easily acknowledged under the microscope and are usually utilized as indicators of the biochemical qualities of wastewater remedy techniques.

The rotating movement of the cilia located on the head of the organism is a sure method to identify the bacteria.  Metabolically, rotifers can be labeled as aerobic chemoheterotrophs.

Crustaceans

Like rotifers, crustaceans are aerobic chemoheterotrophs that feed on wastewater microorganism species like bacteria and algae. These difficult-shelled, multi-cellular animals are a source of foods for fish. (Crabs and lobsters are crustaceans).

Optimizing Routine maintenance Workforce Performance in Drinking water and Wastewater Environments with a CMMS

Write-up by Ajax

H2o and wastewater remedy crops are responsible for offering us with safe consuming drinking water. Water is pumped from different resources like rivers and streams and sent to therapy crops before being distributed to customers. The wastewater treatment method plants acquire waste h2o from sewers and deliver it to the therapy plants. Soon after the remedy treatment the h2o is either produced into the oceans or used for irrigation. The operators in equally vegetation have to manage processes and devices to get rid of harmful substances and microorganisms from the h2o.

These drinking water and wastewater plants depend on computers to keep an eye on their equipment, retailer samples, make procedure associated decisions, timetable and file maintenance processes and offer final results. The workforce in these crops is made up of engineers, chemists, mechanics, laboratory technicians, helpers, supervisors and superintendents. It is also really harmful to function in these remedy vegetation due to prevailing hazards such as dangerous gases, malfunctioning gear, etc. H2o and wastewater environments require a maintenance administration system that can supply solutions for asset servicing administration and boost the effectiveness of the workforce for enhanced productiveness.

Developing Ecosystems in Earth

Interactions are inorganic materials through the forms of light, temperature, humidity and other abiotic factors. In the same importance and participation (interactions) accumulate organic materials such as plants, animals and microbes as interactive partners. Each of the components interact with each other and / or the other when needed and when needed in an ecosystem. This event takes place between plants and animals and pets and animals. Energy flow in these interactions is still in a systematic and advanced dynamics. Interactions require the trust is placed in altitude, longitude and latitude in the biosphere and the equal participation require aquatic and terrestrial ecosystems in living organisms (plants – animals) are presented as dominant factors. These interacting species are fine features of the planet (biosphere) and biotic factors. An ecosystem of plants and healthy animals are always beautiful, it goes without saying. But it is important how an ecosystem operates and maintains the beauty of nature and serve human society. We can say that everything in an ecosystem, producers, herbivores, carnivores, scavengers and scavengers or interact in a set of relationships. How this relationship is all housed in a sustainable ecosystem to provide services to humans is the subject of this article. Ecosystem functions from the basic levels of chemicals and energy. The ecosystem functions that we can learn from natural ecosystems sustain human life and the way we view an estimate of what goods and services are worthy of humanity. Ecosystem functions that teach us to study the functioning of ecosystems give us an idea of why natural systems are durable and can suggest ways to make our system more sustainable human development. As it is said that ecosystems begins at a fundamental level of chemistry and energy, is an atom. Atoms are the building blocks of all cases (all gases, liquids and solids, both living and nonliving sources). Here the molecules and compounds. A molecule consists of two or more atoms linked together in a specific way. The properties of a material depend on the specific way in which atoms are linked to form molecules and atoms themselves. Similarly, a compound formed by two or more types of atoms bound together. A molecule, therefore, may consist of two or more types of atoms linked together, while at least two different types of atoms are always present in a compound. 

In other words, the fundamental units of oxygen gas, which consists of two oxygen atoms linked together, are molecules, but not a compound. The water, however, is both a molecule and a compound, as the fundamental units are two hydrogen atoms bonded to one oxygen atom. In the chemical and the cycle of growth, reproduction, death and decomposition of bodies is an ongoing process taking several atoms of the environment (food), assemble (decomposition), and repeat the process. 
The driving cycle is a general desire, living beings are programmed to grow and reproduce. During growth and decay, the atoms move in the environment in life and then return to the environment. To oversee this process, we must consider the environment as three “spheres”. These are the biosphere, lithosphere, hydrosphere and atmosphere. The biosphere is the sphere (the Earth’s surface), occupied by living beings. The lithosphere is the crust, formed by rocks and minerals. The hydrosphere is the water in all compartments and the liquid oceans, rivers, ice and ground water are the main components of the lithosphere. The atmosphere is the layer of gas (such as water vapor) that separates the Earth from space. The material is constantly exchanged between and within these four areas. 

In a mounted volume on the three areas, living beings are available. Living beings are characterized by six key elements like carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur. These are essential elements in organic molecules that form the tissues of plants, animals and microbes. Regarding the chemical nature of the spheres, we see that the six key elements and others are produced in the environment. 
All organic molecules that form the tissues of living organisms, contain potential energy. When these molecules are burned, the heat and light of the flame is the potential energy being released as kinetic energy. Relationship between the formation and decomposition of organic matter on the one hand, and secure the release of energy and the other is the basis of the ecosystem dynamics of energy. Producers (green plants) with a high potential energy of organic molecules in the environment, namely carbon dioxide, water and some dissolved compounds of nitrogen, phosphorus and other elements. This “up” conversion is possible because producers use chlorophyll to absorb light energy. In addition, all consumers, scavengers and decomposers obtain energy for movement and growth of the food and the decomposition of organic matter produced by the producers. In an ecosystem, this producer is the first trophic level in the state’s energy transformation via one-way from producer to consumer in the food chain. 

At each trophic level, some energy goes into growth (production), some is converted into heat (respiration), and some is emitted as waste or not used. 

The energy that flows from one trophic level to another, only a small fraction is actually spent. This occurred in an ecosystem due to three facts: (1) Much of the previous trophic level stands and biomass is not consumed, (2) much of what is consumed is used for energy, and (3) something that is consumed and digested passes through the body. Energy is lost when transferred to the next higher trophic level, with each successive trophic levels reflect only a fraction of the energy that went into the previous trophic level is usually represented by a much smaller biomass. 

Tests show that the transfer efficiency of a series of ecosystems ranging from 5 to 20 percent, ten being the average. Therefore, there is a loss of about 90 percent of the energy that moves from one trophic level to another. This loss becomes quite critical in higher trophic levels and more so the carnivores are much less abundant than herbivores, carnivores eat other carnivores are less abundant, and so on. In any ecosystem, so there are usually three to five trophic levels, is simply not enough energy to pass through the “supercarnivores.” 

Of course, now that it’s us that what happens to all ecosystems of solar energy that enters? Let’s see how the events occurred in ecosystems. Most of the ecosystems of the energy input is absorbed by the atmosphere, oceans and land, which they heat in the process. The small fraction (2-5 percent) captured by plants is alive and go to the next trophic level or degraded in the most disorganized and most of the energy – heat – the plant decomposes. Finally, all ecosystems of the energy used in the exhaust as heat. 

In accordance with the laws of thermodynamics, no energy is actually lost. As much energy conversions take place in the ecosystem trophic activities, however, that the entropy increases and energy is degraded to a form unavailable for further work. The end result is that energy flows in one direction through the ecosystem, but it is not recycled, so it must be continually renewed by the sun. 

Ecosystem is the nature of the playing area where the continuous transfer of energy from one trophic level to the next trophic level (s) and from one state to another state (s) occurred. From the point of view and possible events that can make an array of ecosystem services and functions that are clear in the global environment. 
# When you look at ecosystem services as “gas regulation is that regulation of gas is regulating the chemical composition of the atmosphere in an ecosystem. His practice in the levels of CO2-O2 balance, O3 for UVB protection and SOx. 
# The ecosystem functions such as regulation of global temperature, precipitation and other biologically mediated climatic processes at global or local, are derived from ecosystem services as “climate control.” Functions ecosystems is evident in the regulation of greenhouse gas emissions, the production of dimethyl affect cloud formation. 
# “Rules of disruption” of ecosystem services is provided by the ecosystem functions such as capacity, damping and integrity of ecosystem response to environmental fluctuations. Ecosystem services are manifested in the storm protection, flood control, drought recovery and other aspects of habitat response to environmental variability mainly controlled by vegetation structure. 

# Regulation of water flows in nature derived from environmental services such as “regulation of the water.” This service water supply for agricultural processes, industrial and transportation. 

The water supply # “The service is linked to the ecosystem retention and storage of water in an ecosystem. The functions of the ecosystem in this regard are the supply of water by watersheds, reservoirs and aquifers. 

Fight against erosion # ‘and sediment retention “ecosystems provide services for soil conservation in an ecosystem. Services are reflected in the prevention of soil loss by wind, runoff or other extraction, storage of sediment in lakes and swamps. 

# The ecosystem functions of soil processes involved in ecosystem services like soil formation. In this case, erosion of rocks and accumulation of organic matter are clear. 

# Nutrient cycling is an important ecosystem service of nature. This service includes internal storage cycle, processing and acquisition of nutrients. 

Aspect of waste management is an important service # ecosystems. In this sense, ecosystem functions is evident in the recovery of mobile nutrients and removal or degradation of excess nutrients and compounds. The ecosystem services is evident in the treatment of wastewater, pollution control, and detoxification. 

# The pollination of the kingdom is in the service of environmental conservation of the wilderness. In this service, the functioning of ecosystems is the movement of floral gametes (the exchange of genetic material). The function is reflected in the provision of pollinators for the reproduction of plant populations. 

# Biological control a service that provides vital ecosystem “trophic dynamics, population control,” such as ecosystem functions. Services are evident in the area of the cornerstone of predators to control prey species, and reducing herbivory by top predators. 

# “Refuge” ecosystem services provides a function of the ecosystem as “habitat for resident and transient.” Characteristics are evident in the nursery area for migratory species, regional habitat for species collected locally or wintering. 

# Ecosystem offers production of food for humans and other organisms. These ecosystem functions are evident in the production of fish, game, crops, nuts and fruits of hunting, gathering, subsistence farming or fishing. 

# The ecosystem services as “raw material” of a part of primary production extractable as raw materials. These services are evident in the production of timber, fuel, or fodder. 

# Ecosystem provides a great service to nature as “genetic resources”. Ecosystem functions are considered the only source of material and biological products. These characteristics are evident in medicine, the products of materials science, genes for resistance to pathogens and pests, ornamental species (pets and horticultural varieties of plants). 

# The ecosystem has a key role in providing recreation services for us. Ecosystem functions that create opportunities for recreational activities. These characteristics are evident in ecotourism, sport fishing and other outdoor recreation. 

# Finally, it shows the same ecosystem can provide services to the cultural aspects of society. Ecosystem function can create opportunities for the provision of non-commercial use. This is evident in the aesthetic, artistic, educational, spiritual, scientific or ecosystems.

The end result is that energy flows in one direction through the ecosystem, but it is not recycled, so it must be continually renewed by the sun. 

Ecosystem is the nature of the playing area where the continuous transfer of energy from one trophic level to the next trophic level (s) and from one state to another state (s) occurred. From the point of view and possible events that can make an array of ecosystem services and functions that are clear in the global environment. 
# When you look at ecosystem services as “gas regulation is that regulation of gas is regulating the chemical composition of the atmosphere in an ecosystem. His practice in the levels of CO2-O2 balance, O3 for UVB protection and SOx. 
# The ecosystem functions such as regulation of global temperature, precipitation and other biologically mediated climatic processes at global or local, are derived from ecosystem services as “climate control.” Functions ecosystems is evident in the regulation of greenhouse gas emissions, the production of dimethyl affect cloud formation. 
# “Rules of disruption” of ecosystem services is provided by the ecosystem functions such as capacity, damping and integrity of ecosystem response to environmental fluctuations. Ecosystem services are manifested in the storm protection, flood control, drought recovery and other aspects of habitat response to environmental variability mainly controlled by vegetation structure. 

# Regulation of water flows in nature derived from environmental services such as “regulation of the water.” This service water supply for agricultural processes, industrial and transportation. 

The water supply # “The service is linked to the ecosystem retention and storage of water in an ecosystem. The functions of the ecosystem in this regard are the supply of water by watersheds, reservoirs and aquifers. 

Fight against erosion # ‘and sediment retention “ecosystems provide services for soil conservation in an ecosystem. Services are reflected in the prevention of soil loss by wind, runoff or other extraction, storage of sediment in lakes and swamps. 

# The ecosystem functions of soil processes involved in ecosystem services like soil formation. In this case, erosion of rocks and accumulation of organic matter are clear. 

# Nutrient cycling is an important ecosystem service of nature. This service includes internal storage cycle, processing and acquisition of nutrients. 

Aspect of waste management is an important service # ecosystems. In this sense, ecosystem functions is evident in the recovery of mobile nutrients and removal or degradation of excess nutrients and compounds. The ecosystem services is evident in the treatment of wastewater, pollution control, and detoxification. 

# The pollination of the kingdom is in the service of environmental conservation of the wilderness. In this service, the functioning of ecosystems is the movement of floral gametes (the exchange of genetic material). The function is reflected in the provision of pollinators for the reproduction of plant populations. 

# Biological control a service that provides vital ecosystem “trophic dynamics, population control,” such as ecosystem functions. Services are evident in the area of the cornerstone of predators to control prey species, and reducing herbivory by top predators. 

# “Refuge” ecosystem services provides a function of the ecosystem as “habitat for resident and transient.” Characteristics are evident in the nursery area for migratory species, regional habitat for species collected locally or wintering. 

# Ecosystem offers production of food for humans and other organisms. These ecosystem functions are evident in the production of fish, game, crops, nuts and fruits of hunting, gathering, subsistence farming or fishing. 

# The ecosystem services as “raw material” of a part of primary production extractable as raw materials. These services are evident in the production of timber, fuel, or fodder. 

# Ecosystem provides a great service to nature as “genetic resources”. Ecosystem functions are considered the only source of material and biological products. These characteristics are evident in medicine, the products of materials science, genes for resistance to pathogens and pests, ornamental species (pets and horticultural varieties of plants). 

# The ecosystem has a key role in providing recreation services for us. Ecosystem functions that create opportunities for recreational activities. These characteristics are evident in ecotourism, sport fishing and other outdoor recreation. 

# Finally, it shows the same ecosystem can provide services to the cultural aspects of society. Ecosystem function can create opportunities for the provision of non-commercial use. This is evident in the aesthetic, artistic, educational, spiritual, scientific or ecosystems.

Present Situation of Drinking Water in Pakistan

Present situation OF DRINKING WATER in pakistan

Image via Wikipedia

      Currently over 65 percent of Pakistan’s population is considered to have access to safe drinking water.  Huge disparities, however, exist with regard to drinking water coverage between urban and rural areas and provinces/regions.  The quality of the drinking water supply is also poor, with bacterial contamination, arsenic, fluoride and nitrate being the parameters of major concern.  Sustainability of the existing water supply systems is also a major issue in the sector. 

  Inadequate water supply, sanitation and hygiene result in high incidence of water and sanitation related diseases in Pakistan, which in turn increase morbidity and mortality rates and pose a major threat to the survival and development of Pakistani children.  It has been estimated that water, sanitation and hygiene related diseases cost Pakistan economy about Rs.112 billion per year, over Rs.300 million a day, in terms of health costs and lost earning.  Out of this, the cost associated with diarrhea diseases alone is estimated to range from Rs.55 to Rs.80 billion per year. 

SOURCES OF DRINKING WATER

       The main source of drinking water in Pakistan is the hand pump. Hand pumps and motor pumps together provide 65 per cent of household, drinking water. However, various surveys show that the usage of Hand pump is declining where as it is increasing in motor operated pumps both in urban and rural areas. Moreover, the percentage of households depending on lower water sources i.e. deep well, and others either remained unchanged or slightly decreased. Usage of tap water during 2004-05 and 2005-06 remained at the level of 34 percent, Khyber Pakhtoonkhawah province had the best water supply of 47 percent in 2005-06 compared to 44 percent in 2004-05 amongst the provinces in terms of tap water. The vast majority of the population of Punjab (68 percent) has water either from hand pump or motor operated pump and only 5 percent of the population depends on a dug well or other sources ( river, canal or stream). Sindh has remained at almost the same level in terms of tap water (43 percent) in 2005-06 as compared to 44 percent in 2004-05. Balochistan province has shown increase in Tap water from 33 percent in 2004-05 to 36 percent in 2005-06, increase is more evident in rural areas (22 percent to 25 percent) in spite of the fact that in urban areas same has declined. The water supply situation in Khyber Pakhtoonkhawh (KPK) and Balochistan has improved as compared to 2004-05. In these two provinces, 32 and 60 percent of the rural population in 2005-06, as compared to 45 percent & 70 percent respectively in 2004-05, depend on water from a deep well or from river/canal/stream.

Richer households are substantially more likely to have piped water in their household. This relationship is strong in urban areas, but very weak in rural areas. On the other hand the use of deep wells and river/canal/stream is more likely for poor households. A small proportion of households pay for drinking water. Only 24 per cent of households pay for water in urban areas and 12 per cent in rural areas. Since 2004-05, paying segment of population kept increasing in rural and in urban areas.

       The 2005-06 Pakistan Social & Living Standards Measurement Survey (PSLM) recorded information on WHO installed water systems used by the household. It shows that households themselves are the largest single supplier of drinking water, having arranged their own supply in 57 per cent of cases. Provincial and local governments in the form of the LG&RDD, the PHED and other local government bodies, installed water supplies of some 35 percent of households. They installed 92 per cent of all piped water supplies; however the coverage of Local government was least important in Punjab and played the largest role in Balocistan. Households that depend on the poorest supplies also have to travel the furthest for the water. Some 8 percent of households whose drinking water comes from a river, canal, stream or pond travel zero to 0.5 km for the water. Comparing provinces, Punjab is favoured with the best access while Balochistan has the worst, with over half of the households depending on sources outside the home.

RURAL DRINKING WATER POLICY

Image via Wikipedia

Drinking water, as referred to in the Policy, means that the water used for domestic purposes including drinking, cooking, hygiene and other domestic uses.  The term “safe water” refers to the water complying with National Drinking Water Quality Standards.  Access means that at least 45 and 120 liter per capita per day of drinking water is available for rural and urban areas, respectively, within the house or at such a distance that the total time required for reaching the water source, collecting water and returning to home is not more than 30 minutes. 

goals and objectives

The overall goals of the National Drinking Water Policy is to improve the quality of life of people of Pakistan by reducing incidence of death and illness caused by water-borne diseases through ensuring provision of adequate quantity of safe drinking water to the entire population at an affordable cost and in an equitable, efficient and sustainable manner.  The objectives of the Policy are to:

Existing data collection systems such as Pakistan Social and Living Standards Measurement Survey, Multiple Indicator Cluster Survey, Demographic and Health Survey and Population Census are being streamlined and strengthened to ensure availability of authentic information for assessment of the progress with regard to enhancing access to safe water as well as for decision making purposes; 

Drinking water sector management information system have been established at the Federal, Provincial and local levels;

In order to ensure effective utilization of resources and to maximize impacts, inter-sectoral approach has been promoted and implementation of the Policy is being coordinated and integrated with relevant national policies, especially Policies for sanitation, water, environment, health and education sectors;

Adequate allocations are being made for provision of drinking water supply facilities in educational institutions and health care facilities under the education and health sector programmes; and

In order to ensure inter and intra-sectoral coordination, a multi-stakeholder Water and Sanitation Coordination Committee has been established.  Similar committees are being established at the Provincial, District and local levels.

Legislation

Pakistan Safe Drinking Water Act has been enacted to ensure compliance with the National Drinking Water Quality Standards and hold water supply institutions accountable to the general public;

The Drinking Water Quality Standards are being enforced throughout the country and agencies responsible for the provision of water supply to ensure the quality of water supplied by them conforms to these standards;

Water Conservation Act and relevant standards and guidelines are being enacted;

Standards for water-saving plumbing equipment and appliances are being enacted;  and

Legislation for regulation of groundwater exploitation is being enacted.

Drinking Water and Sanitation (under MDGs)

Provision of safe drinking water, adequate sanitation and personal hygiene are vital for the sustainable environmental conditions and reducing the incidence of diarrhea, malaria, trachoma, hepatitis A & B and morbidity levels. Not having access to water and sanitation is a deprivation that threatens life, destroys opportunity and undermines human dignity. Thus, investing in the provision of safe water supply is not only a development oriented strategy in itself, it can also yield other socio-economic benefits in terms of improved health status, quality of labour force and reduced burden-of-disease.  Following are some of the major achievements in the sector:-

Drinking water supply coverage increased from 65 percent (55 rural; 85 urban) to 67.3percent (56.3 rural; 87 urban), during 2005-07.

Sanitation and drainage coverage increased from 42 percent (30 rural; 65 urban) to 43.3 percent (31.3 rural ;63.3 urban) during 2005-07, as elaborated in the following figure:

Coverage of Drinking Water and Sanitation

Under “Clean Drinking Water Initiative (CDWI)’, costing Rs 495 million, one water purification plant (WPP) in each Tehsil of Pakistan, AJK, Gilgit-Baltistan, and FATA installed,

The second project called “Clean Drinking Water for All (CDWA)’ costing Rs 15 billion is under implementation to install one Water Purification Plant (WPP) in each Union Council of Pakistan, AJ&K, Gilgit-Baltistan, and FATA. Spadework including mechanism to implement has been completed. By June, 2007 Rs 6.5 million has been utilized under CDWA, further it shall be extended to village level where filtration plant shall be provided for clean drinking water.

Following are the key issues of the sectors:

Major issues facing the water supply sector are:

Absence of an integrated approach,

Sub-optimal use of water,

Inadequate storage capacity,

Extensive system losses,

Inadequate operation and maintenance and poor cost recovery,

Excessive groundwater pumping without recharge,

Unsafe disposal of wastewater,

Lack of private sector participation,

Inefficient institutional capacities,

Poor linkage among urban and rural water development projects,      

Water pollution including metal contamination generating public health hazards.

Inadequate water and sanitation services to the poor increase their living costs, lower their income earning potential, damage their well-being and make life riskier.

The majority of population in the country is exposed to hazards of drinking unsafe and polluted water and inadequate sanitation.

Continuing urbanization, growing populations and increasing industrialization have increased water consumption and correspondingly generating higher volumes of waste-water and solid-waste.

Most of the waste-water is not treated and the expansion of the urban water supply schemes without treatment facilities (at source) are threats to human health and natural environment.

Community Participation and Empowerment (WATER)

Participation of communities, especially women and children, in planning, implementation, monitoring, operations and maintenance of water supply systems are being encouraged to promote community ownership and empowerment as well as sustainability;

Every public sector project have special allocation for community mobilization;

Community mobilization units are being established in water supply related institutions;

 Special focus has been placed on gender training programs for the staff of water supply related institutions at all levels so that they are able to respond in a sensitive manner to the gender differentiated needs in the drinking water sector; 

Special efforts are being made to recruit and induct women in water supply related institutions and other relevant agencies to ensure that the needs of women are adequately addressed in design and operation & maintenance of water supply systems; and

Representation of women councilors in all review and decision making forums regarding drinking water supply at the District, Tehsil and Union Council levels have been ensured.

Public Awareness

Intensive information, education and communication campaigns are being developed and implemented to promote water safety, water conservation and safe hygiene practices. To this effect, a National Behavioral Change Communication Strategy has been formulated and implemented; and

Hygiene promotion is being made an integral component of all water supply programmes.

Public-Private Partnership

Private entrepreneurship and public-private partnerships for enhancing access to safe drinking water, operation and maintenance of water supply systems, resource mobilization and capacity development are being promoted.  The role of civil society organizations to support government’s efforts in this context are also be encouraged.

Commercial Wastewater Treatment

Article by Hardboss

Global scarcity of water resources available for consumption will reach 35 percent in around 10 years or so. We need to find effective ways to reuse our commercial wastewater, the main idea is twofold: First, develop water-saving technologies; second is to increase the supply of water, such as sewage Water Department Management and reuse, desalination and so on.

In recent years, water-saving technologies have been created at a very rapid pace. In Vienna, we take our water resources very seriously.  Many people who have been to Vienna, the city will be impressed by the fine quality, every household will tap out the sweet and cool water, often in Vienna here and say that the water unique in the world.  The City of Vienna which is close to the Danube, and we are not able to use the Danube for a water supply, do to the river’s poor water quality. Conversely, Vienna relies on mountain spring water which is located about 40 Km from Vienna. The water primarily comes from mountain forest spring water. The inhabitants of Vienna demand tasteful spring drinking water.

Recently, we interviewed key wastewater engineers stationed at the main sewage treatment plant in Vienna. The plant is not only Europe’s largest and most modern sewage treatment plants, but is also an Innovation Achievements Exhibition center. Vienna’s head of the main sewage treatment plant is Mike Laosi.  The lead engineer informed us that when the sewage treatment plant was built in Vienna, the city selected the lowest point Ximo Ling area.

The wastewater treatment plant was put into operation in 1986, and was built on  property belonging to the City of Vienna. The Commercial sewage treatment plant was designed to meet the needs of about four-hundred-million people. The waste water pipeline travels more than 2300 km. This distance corresponds to the Austrian capital Vienna to Lisbon the distance, quite an engineering marvel. The city of Vienna now has over 1.7 million people which produce about 200 million cubic meters of sewage a year. Ninety-eight percent of the population living in the city discharged into the public sewer system.

The wastewater  requires about 20 hours of treatment before it is discharged into the Danube. New wastewater regulations were imposed on the city to meet European Union and Austria’s new regulations in 2005. Vienna’s municipal government invested 220 million euros in the Vienna-based Sewage Treatment Plant Phase II expansion of the sewage bio-processing equipment. The expansion improved the water quality of rivers in the Vienna area, while allowing the main sewage treatment plant in Vienna to become the EU’s key environmental demonstration project. Expansion project designer, Professor University of Vienna, Helmut  Keluoyisi indicated that the Phase II extension of the Vienna main sewage treatment plant has become the most important city of Vienna Water Pollution Control facility.  Advanced technology for sustainable environmental development Vienna international reputation continue to be one of the top European cities. Vienna Main Sewage.

The main sewage treatment plant goes through mechanical treatment and biological treatment in two phases. Through these two processes, urban waste water is reduced more than 95% carbon, 80% of  total nitrogen, phosphate and more than 90% to 95% of organic pollutants have been removed. The main sewage treatment plant effluent today cleans about 100 tons of carbon, 30 tons of nitrogen and 5 tons of phosphate. The entire process produces large quantities of organic Sludge which is transported to the remote heating plant and burned. The heat produced is used to heat the and generate city electricity.

The sewage treatment plant uses modern management systems and is operated by approximately 159 employees. Sewage entering the treatment plant goes through a series of treatment processes. The first process is a mechanical purification process.  In the mechanical treatment process, the sewage waste larger particles are removed, also know as solids separation. This first step removes over 15 tons of gravel each week and other larger solids.

The second step, six water screw pumps move water up to the high-end of the plant. Each pump moves about 4500 liters per second.

The third step, water flows through a fine sieve. The sieve removes 6mm and larger solids from the waste stream.

The fourth step, a sub-channel device contains water flow control channels which flow at about 10 cm / sec.  This flow rates allows for solids sink to the bottom. About 5 tons per day of solids are removed in this “settling process.”

In the 5th step, the sewage flows to primary sedimentation tank.   Additional wastewater sludge is precipitated in the sedimentation tankage which produces about 80 tons per day.  The remaining activated sludge is pumped into activated sludge holding (ASH) tanks. The ASH act as a storage mechanism to recycle activated sludge to the process inlet, as needed. To complete the mechanical sewage treatment phase, after the initial purification of waste water to flow into the second phase of the bio-purification equipment. In the second phase of expansion before the biological treatment process, the main sewage treatment plant in Vienna with only a simple biological wastewater treatment, mainly through the mechanical purification of sewage let into another open sedimentation tanks, sedimentation tanks of the ventilation system which is used for extended aeration of the wastewater stream.  This overall process operates at better than 95% BOD removal efficiency. With final wastewater filtration, Total suspended solids (TSS) are reduced to less than 10 mg/L.

This remarkable wastewater treatment facility is one of the largest plants in Europe and needs to be reviewed, just based on its sheer size.

Addressing the Issue of Wastewater Treatment

Article by Goldcrest

For many different industrial sectors in the United Kingdom, the safe disposal and treatment of waste water from their plants and factories remains a key area of concern for their businesses. Companies in the UK both big and small are bound by strict regulations regarding their wastewater treatment and management – and addressing such issues in an economically and environmentally sound manner is not at first glance, easily achieved. For this reason, companies across many different industry sectors including mining, quarrying, chemical and pharmaceutical sectors will always be on the lookout for a highly effective solution to their waste water treatment needs that is not only compliant with all of the regional environmental regulations that govern their industry sector – but that are also financially viable, environmentally sound, tested and also scalable – but can most importantly remain within the budgetary constraints of their company.

Although not necessarily immediately known to the general public, there are in fact several tried and tested chemical solutions that can be used to address the issue of large scale industrial waste water treatment and management that have been deployed successfully across numerous UK industry sectors to great effect. The use of chemicals treatments such as flocculants and coagulants for example are a technologically advanced solution to wastewater treatment which have been uptaken by companies who are seeking to dramatically cut their disposal costs, whilst simultaneously looking to improve the company performance in the areas of both effluent treatment and their water recycling systems. Through the correct implantation of these chemicals by experts in these fields, many companies are finding that it is now possible to achieve industry compliant water treatment solutions whilst cutting their costs.

At a time of great economic difficulty and strain that has hit particularly hard in industrial sectors such as mining and extraction and the manufacturing industries in the United Kingdom, companies are understandably seeking to save money in as many ways as they can whilst remaining compliant within the regulations of their industry sector. The implementation of up and coming technologies such as flocculants and coagulants as a cost effective solution to waste water treatment and management seems set to help further revolutionize the way companies operate and help save them money at a time when they need it the most.

Suppliers of flocculants and coagulants for waste water treatment.










VICTORIA – One day after the CRD voted to move ahead with sewage treatment in the Capital Region, the Mayor of Victoria made the rounds, selling the idea to his people. This morning CFAX radio listeners got the hard sell as he spun the numbers. Mayor Dean Fortin reassured listeners in the CRD that the cost would be just per month, per resident for the biggest, most expensive infrastructure project on Vancouver Island. He equated the cost to the cost of garbage pickup. It’s a way of looking at the cost that, for some taxpayers, is easier to swallow. In a matter of weeks, a plan must be presented to the Province, but as the deadline looms, one opposition group says it is not too late to say no to secondary sewage treatment and it will do what it takes to prevent the facility from being built. “We’re willing to move heaven and earth to stop this,” Said John Bergbusch, chair of the Association for Responsible and Environmentally Sustainable Sewage Treatment. But could they actually stop it? CRD Director Judy Brownoff says the region could face hefty fines, up to 0000 per day, if it doesn’t comply with new federal and provincial regulations. Environment Minister Barry Penner says the city has a “legal requirement” to follow through with the secondary sewage treatment plan. There’s a real sense of urgency for the CRD to put their stamp of approval on their sewage treatment plan so it can be on Minister Penner’s desk by the end of the year. Nay-sayers feel the pressure
