Sewage treatment is extremely important in our culture. It’s an place that is usually misunderstood if comprehended at all. Nonetheless, treatment method plants have a number of important features.

How to recognize a sewage treatment plant

A sewage therapy plant is also identified as a domestic wastewater therapy plant. Basically, what the procedure requires is cleansing up the sewage which is produced from domestic and industrial resources. Normally this isn’t going to involve cleaning up waste which is launched from especially dirty sources, for instance, greatly industrial firms or factory farms of nuclear reactor coolants.

The functions of vegetation

In modern day sewage treatment method crops there are 3 main stages: major, secondary, and tertiary.

*Primary: In this 1st phase the easy-to-eliminate substances are taken out from the wastewater. For instance, fats and oils are skimmed from the surface area, rocks and items of grit are strained, and any significant pieces of rubbish can be raked out.

*Secondary: In the second phase the primary purpose is usually to get out as many biological contaminants as feasible. The secondary therapy is the stage at which the greatest technical differences in sewage treatment method can arise. This is due to the fact there are a range of techniques in which biological contaminants can be decreased in wastewater. Getting said that, typically microorganisms are utilized to get rid of any undesired components.

*Tertiary: In this last stage the goal is to make the drinking water as thoroughly clean as achievable just before it re-enters the setting. Usually this is attained by synthetic or guy-produced normal filter techniques. Occasionally therapies are also utilized to get rid of any phosphorus or nitrogen located in excess. Then, the remaining water is disinfected. Chlorination or UV therapy is generally employed for this method.

Crucial factors

The sludge which is left around from cleaning the wastewater has to be dealt with individually and differently to the drinking water that is released. This is an essential added operate for treatment method crops. In common, this is taken care of by utilizing anaerobic and aerobic strategies which utilize bacteria. Composting can also be employed to break down any biological contaminants of the waste.

Treatment plant myths

Many individuals are below the impression that the drinking water which happens out of a plant is clear. This is a common misconception: the perform of a plant is to make the h2o cleaner, but it can be not cleanse enough to consume. It could be used in irrigation. What a plant is trying to do is to simply pace up a process which would normally occur presented far more time. This indicates that a plant can create water which is secure to enter again into the h2o system as it really is so greatly diluted. The river then continues the h2o purification, acting as a form of fourth phase.

A sewage treatment plant has key functions. It is an crucial component of dealing with waste, be it domestic or industrial, and assists sustain a clean drinking water provide.

New Technology Selection Of Residential Wastewater Treatment Packaged Plants


by Bruce Bosshard, PE

BnB Engineering conducted a review of residential wastewater treatment systems on the market today. Our review picked Norweco Singulair as the top manufacturer. Norweco wastewater has been in operation for over 100 years. During this period, NORWECO has continuously improved wastewater products from basic residential septic tank designs, and then extended aeration systems which have evolved into the NORWECO SINGULAIR line of products. The SINGULAIR line of products has superior wastewater treatment performance, including built-in; 1)Robust effluent filtration, 2) Wastewater De-nitrification, 3) Chlorination capabilities and UV Disinfection, 4) De-chlorination capabilities, 5) Flow Equalization, 6) Wastewater treatment capabilities to U.S. drinking water standards., 7) Low costs, 8) 50-year warranty exchange program

BnB views NORWECO SINGULAIR as the best residential wastewater treatment packaged plant on the today’s market. GEOFLOW, a leader in drip irrigation products, is teamed with NORWECO to provide add on drip irrigation products. GEOFLOW recognizes that SINGULAIR’s top residential wastewater treatment performance is unparalleled. The best wastewater treatment performance, including de-nitrification (NSF 40 certified) sets NORWECO well above extended aeration competing systems. In BnB’s final decision, we included NORWECO SINGULAIR’s competitive pricing, demonstrated NSF-40 certified performance, a long track record (100 years) in continuous improvement and innovation as key factors.

The following is a general Discussion on our Pick. To provide a robust wastewater treatment system you need to incorporate the following into the basic design; 1) One-day pretreatment, 2) One-day aeration/extended aeration, 3)Flow equalization, 4) Filtration, 5) Tertiary treatment for de-nitrification, 5) Built-in Chlorination and De-Chlorination

All NORWECO SINGULAIR systems include a minimum of 1-day wastewater pretreatment. NORWECO requires stringent quality assurance. One key to SINGULAIR success is that standard precast tank molds are used by all distributors. This standardization makes certain that there are little variations from one caster to another. Competing systems often allow concrete tank casters to use existing molds. Holes are generally cut in each tank and their one-size fits all units are placed in the holes. These competing systems lack the conformity of SINGULAIR systems, therefore, their performance is not always consistent. In SINGULAIR systems, pretreatment is accomplished by requiring a minimum of 1-gallon solids separation tank capacity for each gallon of maximum daily wastewater flow. SINGULAIR designs ensure that larger packaged systems increase solids tank capacity accordingly. The basic SINGULAIR systems are 600, 750, 1,000, 1,250, and 1,500 gallons per day (GPD). Each configuration mandates that pretreatment tank capacity is increased accordingly. NORWECO provides ALL distributors with approved concrete molds which ensure tanks are always the same. This mandate ensures adequate stage-one residential wastewater treatment and consistent NSF-40 performance.

Similar to pretreatment tank capacities, minimum aeration tank volumes are increased according to maximum estimated GPD flows. The increase in aeration tank size promotes a minimum of 1-day aeration. Also, as aeration volumes are increased, the number of aerators are increased to ensure adequate aeration capacity (1,000, 1,250, and 1,500 GPD units have two aerators.). NORWECO SINGULAIR utilizes a stirring technology (the only moving parts) which minimizes the airflow into the system. The low airflow (2-4 cubic feet per minute (CFM)) minimizes odors which are generally associated with extended aeration systems. The aeration flow dissipates into the surrounding soil, which minimizes smells from the systems. Competing systems, that we looked at, use excessive air-flow (over 20 CFM) to stir the wastewater. This continuous-high-airflow rate causes bad odors in the general area of the pipe outlet. Also, when the tank is continuously aerated, there is no possibility for de-nitrification, since the anoxic conditions are required for de-nitrification.

Flow equalization is accomplished by maintaining the Bio-Kinetic (BK) module height within +/- one inch. The SINGULAIR TANKS are constructed with about 6-inches of minimum free board. The BK-module has a series of small holes in each side of the module. As tank level increases, slow flows of wastewater are allowed through the holes. The systems can easily be expanded to multiple treatment units, if designs ensure that all the treatment units are at the same elevation. BnB refers this configuration as a treatment node. Here the SINGULAIR system can be expanded to much larger treatment nodes, with limits at about 6,000 GPD.

The BK module also promotes superb filtration and de-nitrification. To reach stringent NSF performance requirements for total suspended solids (TSS), SINGULAIR BK modules possess a robust group of contact discs which in turn precipitate out the vast majority of TSS. Once again, the BK module design and style is patented and can’t be integrated into competing systems. We’ve observed effective BK module filtration up to 1. 5 years of operations, without servicing. The comprehensive filtering capability in the SINGULAIR BK module provides this robust promise. Competing devices evaluated depend on straightforward filtration for example bags or filters which are high priced as well as require quarterly check up, cleansing and-or replacing. The SINGULAIR BK modules have numerous “stacked plates” that are comparable to commercial clarifiers. The stacked pates enable de-nitrifying bacteria (anaerobic bacteria -absence of oxygen) to fill the plates. The FE, slowly and gradually flowing residential wastewater flow, passes within the plates and the micro organism decreases the nitrogen or de-nitrifies the treated wastewater flow. This revolutionary approach has demonstrated, in some designs, to lower total nitrogen to under 5 mg/L (drinking water standard is less than 10 mg/L total nitrogen).

BK-modules can be readily converted to include both chlorination and de-chlorination. The top of the BK-modules are constructed to receive tubes which can be fitted with chlorination or de-chlorination tablets. Since the BK-modules provide low-equalized-flows, the tubes utilize specially formulated tablets that function well at low flow rates. The Chlorination/de-chlorination tubes cost about $75 each. Therefore, for about $150 the systems can be converted to chlorination disinfection units. This is a very cost-effective option. A few states, including TX requires that FE, reliable chlorination, and filtration devices be added to the effluent of most competing systems. NORWECO gladly provides them BK-2000 modules. The BK-2000 is a small tank that contains one BK-module. In re-use applications, this add-on allows the competing systems to perform at more-reliable and higher standards.

We consider NORWECO SINGULAIR costs as highly competitive. The NORWECO SINGULAIR systems are distributed locally by authorized NORWECO distributors. Costs (controlled locally by the NORWECO distributor), for a single family residence (up to 600 GPD wastewater flow) range from $3,500 to about $5,000 per unit. The NORWECO SINGULAIR GREEN systems cost approximately $800 to $1,000 more per system, depending on location. The advantage of the SINGULAIR GREEN system is that it can be transported to remote areas and placed with a standard backhoe (weighs approximately 1,000 pounds). Please send us a comment; if you are interested in SINGULAIR or SINGULAIR GREEN systems.

BnB Alternative Septic Solutions, LLC chooses NOWECO SINGULAIR as the top residential wastewater treatment system on the market today. NORWECO is also teamed with GEOFLOW drip irrigation systems and provides integrated wastewater reuse systems. The best wastewater treatment performance, including de-nitrification (NSF 40 certified) sets NORWECO well above competing extended aeration systems.

We consider NORWECO’s demonstrated performance, price and the technical -principles of the SINGULAIR design when rating NORWECO SINGULAIR as the top residential wastewater treatment system on the market today.

General Discussion

To provide a robust wastewater treatment system you need to incorporate the following included in the basic design:

  1. One-day pretreatment
  2. One-day aeration/extended aeration
  3. Flow equalization
  4. Filtration
  5. Tertiary treatment for dentrification
  6. Built-in Chlorination and De-Chlorination

One-day pretreatment

All NORWECO SINGULAIR systems include a minimum of 1-day wastewater pretreatment. Pretreatment is accomplished by requiring a minimum of 1-gallon solids separation tank capacity for each gallon of maximum daily wastewater flow. SINGULAIR designs ensure that larger packaged systems increase solids tank capacity accordingly. The basic SINGULAIR systems are 600, 750, 1,000, 1,250, and 1,500 gallons per day (GPD). Each configuration mandates that pretreatment tank capacity is increased accordingly.

 

One-Day Aeration

Similar to pretreatment tank capacities, minimum aeration tank volumes are increased according to maximum estimated GPD flows. The increase in aeration tank size promotes a minimum of 1-day aeration. Also, as aeration volumes are increased, the number of aerators are increased to ensure adequate aeration capacity (1,000, 1,250, and 1,500 GPD units have two aerators.). NORWECO SINGULAIR utilizes a stirring technology (only moving parts) which minimizes the airflow into the system. The low airflow (2-4 cubic feet per minute (CFM) minimizes odors which are generally associated with extended aeration systems. The aeration flow dissipates into the surrounding soil, which minimizes smells from the systems. Competing systems use excessive air-flow (over 20 CFM) to stir the wastewater. This high airflow rate causes bad odors in the general area of the pipe outlet. Also, when the tank is continuously aerated, there is no possibility for de-nitrification, since the anoxic conditions are required for de-nitrification.

Flow Equalization

The flow equalization is accomplished by maintaining the Bio-Kinetic (BK) module height within +/- one inch. Each 6,000 GPD treatment node consists of four 1500 GPD Singulair units with a 6,000 gallon pre-treatment tank. Surges to the treatment nodes are regulated by the patented BK modules. Each BK module has ¼ inch holes at two elevations which will incorporate any surges and equalize flow between BK modules. The slow throughput promotes equal flow between the four 1,500 GPD units.

Filtration and De-nitrification

The second function of the BK-Module(s) is to filter particulates from the wastewater stream. The BK-Module has a series of contact plates which cause most particulates to precipitate out of the wastewater stream. Also, the BK-Modules are generally operating in the absence of oxygen (anoxic conditions), which promotes the buildup of de-nitrification bacteria. These bacteria eliminate total nitrogen from the wastewater stream. Once again, this patented configuration minimizes surges in the residential wastewater flow rates, which minimizes exceeding of wastewater treatment effluent goals. The NORWECO SINGULAIR aerators cycle 1-hour on and 1-hour off, promoting anoxic conditions for about 50 percent of the time. During the anoxic cycles, de-nitrification of the residential wastewater stream occurs.

 

 

 

Built-in Chlorination and De-Chlorination

Each BK-Module has the built-in capability to insert chlorination and de-chlorination tablet holders. This low-cost residential wastewater disinfection option (about $75) is quite unique. Since the chlorinator is built into the BK-module, wastewater flows are equalized and generally flow through tow ¼ holes. This slow contact rate with the chlorinators ensures reliable chlorination of the residential wastewater stream.

Costs

The NORWECO SINGULAIR systems are distributed locally by authorized NOWECO distributors. Costs (controlled locally by the NORWECO distributor), for a single family residence (up to 600 GPD wastewater flow) range from $3,500 to about $5,000 per unit. The NORWECO SINGULAIR GREEN systems cost approximately $800 to $1,000 more per system, depending on location. The advantage of the SINGULAIR GREEN system is that it can be transported to remote areas and placed with a standard backhoe (weighs approximately 1,000 pounds).
