chlorination, ultraviolet (UV) processes or by applying Ozone. Disinfection is generally required if the waste stream has the potential to come into contact with the general population, or drinking water supplies. The overall goal is to reduce the infection risk to the surrounding population.

Chlorine Disinfection

 

The least expensive and most common type of disinfection is by chlorination. Generally, the wastewater stream passes over chlorine tablets (known as contact chlorination) which increases the chlorine concentration in the wastewater. The increased chlorine concentration is very effective in killing most harmful pathogens.

The second type of contact chlorination is a batch process. In batch application(s), the wastewater fills a large tank, where sufficient chlorine is added to kill most pathogens. In batch processing, the chlorine is added manually as a powder or as chlorine gas.

In sensitive areas, the chlorinated wastewater stream can be passed through de-chlorination tablet feeders to neutralize the chlorine prior to discharge. One disadvantage is that salts are introduced into the environment via the chlorination/de-chlorination process.

Ultraviolet Disinfection

Ultraviolet disinfection (UV) uses no chemical in the treatment, and the treated water is not subjected to the salts produced in chlorination processes. One significant disadvantage is that the UV disinfection systems require constant maintenance and a power source. UV light bulbs or windows must be cleaned regularly and bulbs replaced.

Ozone Disinfection

Third type of chlorination method is Ozone. Ozone if a very effective and fast-acting disinfection method. Generally, the Ozone is produced onsite and is introduced into the waste stream. Ozone disinfection requires higher power supplies to run, but is relatively safe. Maintenance requirements complicates the Ozone process and its reliability.

We recommend using Chlorination tablet feeders and the applicable Chlorine tablets to disinfect most wastewater streams. We feel that the NORWECO Chlorine tablet feeders, and the NORWECO Disinfection tablets are the best on the market. Please visit our online store for pricing.

the grade of ammonia concentration in each commercialized point, dangers to users who directly interact this toxic chemical tinned not be eliminated entirely.

 

Even in a very depression titer, inhaling breath with ammonium, or acquiring the brine on your cutis tin solon often antecedent trauma variety combustion, fainting or, termination, decease. Since ammonium is used often industrially, we should be alarmed of their impurity ware that usually issue into effluent. With these fact, we should be wary about how to distance ammonium from impurity H2O.

 

There are several ways in removing excess ammonia in the wastewater.

One of the methods developed is with the use of a Steam Stripping, Catalytic Oxidation and Self Steam Compression. These are some of the technological scheme developed to say-so the ammonia level in the wastewater. It will all start with the ammonium-people wastewater, Fed into the Ammonia Stripper. This wastewater will be heated up with the help of vapour. Then, the ammonia in the effluent will be divest into the vapor, which would produce ammonium-rich steam. This ammonia-rich vapor will be released from the stripper and then it will go directly to what we call the Steam Compressor. Now while inner the steam compressor, the ammonia-rich steam will be reheated and then the ammonia-rich steam will then be utilized as the energy supply for the Reboiler. Another procedure will take spot in the Reboiler. After the energy trading at the reboiler, the ammonia-people vapour will go to the Ammonia Catalytic Converter. The converter will then decompose the steam and turn parts of it into Nitrogen and some into just regular gas. After all the reactions that happened, it is important to know that the state would photo contain some minute amount of ammonia. The gas would be cooled down, and then they would release it.

 

Although the gas contains harmless amount of ammonia, if it will accumulated, it’s pretty much hazardous too. So another method proposed is by using Nitrifying bacteria. This pedagogy is certainly Earth-friendly because these bacteria are course hap in our context and they also convert the redundant ammonia into thing that can be useful to other organism. There are two kinds of Nitrifying bacteria that works on the surplusage ammonium. The first ace is the Nitrosomonas spp. convert the excess ammonia into Nitrite. This nitrite will be then converted to Nitrates by the sec nitrifying bacteria called Nitrobacter spp. The nitrates can now be maximized by the organisms that need it.

 

Membrane constructor is also a popular mode on eliminating surplus ammonium in the dross H2O. In this drumhead constructor, the ammonium will be eliminated immediately and then will be converted into some sort of ammonium acetate. It’s kind hit II birds with unity rock. You’re eliminating ammonium in the effluent and at the Saame clip, you tin also brand chance by profiting with this ammonium acetate.

 

In Japan, they are really fashioning efforts in discovering ways on how they can eliminate ammonia in waste water. Their government is mandating that ammonium should only be no more than 100 ppm in water.

The plant has a capacity of eighty thousand gallons per day (regular) it serves the “Maztal Casino, Resort & Conference Middle” and it serves other services in the reservation these kinds of as housing, tribal administration amenities and gentle commercial stores.

When considering WWTP designs BnB generally likes to see more De-centralized wastewater treatment. We strongly feel that limits should be placed on how far we pump our waste streams. At the minimum a 30/30 (BOD/TSS) treatement should be considered if pumping the sewage in excess of a one-mile distance. For example in San Diego, CA every heavy rainfall generally causes relief valves to lift and raw sewage is released into the washes. This causes hazardous pathogen levels in nearby beaches for days or weeks.

By treating wastewater in nodes and then pump the treated water vice raw sewage, releases have minimum environmental hazards/impacts. We advocate distributive treatment vice large-mega centralized treatment to minimize these sewage transfer hazards.

Commercial Wastewater Pumping Stations Review of Bio-microbics’ BioSTEP® and NORWECO

 

Article By Bruce Hardboss, PE

 

 

BioSTEP® screened pumping schemes are versatile ticker packet designed to transferral screened liquid in numerous size-diam, decentralized accumulation applications. BioSTEP® is a registered trademark of Bio-MICROBICS.  Bio-MICROBICS claims the following; “BioSTEP® screened pumping systems are designed so that once installed, all normal operation and maintenance can occur without the messy removal of system components. BioSTEP screened pump vaults utilize the patented SaniTEE® screening technology to screen and deflect solids rather than collect and hold them like other filtering technologies. ” (see http://www.biomicrobics.com/?p=67&s=10) This article is the sole property of BnB Alternative Septic Solutions, LLC and does not necessarily reflect NORWECO’s position. We feel that our evaluation is technically correct and we welcome constructive comments.

At BnB Alternative Septic Solutions, LLC our registered professional CIVIL Engineers prefer simple NORWECO grinder pump configuration(s) or the robust BK-2000 filtration system followed by a standard NORWECO pump unit. Bio-MICROBICS advocates their BioSTEP® product as superior to filtration systems. We strongly feel that for flows up to 2000 GPD, a BK-2000 system provides robust filtration and is a simpler approach when compared to the BioSTEP® system. We also feel that adding grinder pump units to a standard septic tank outlet is also a “more simple design.”

Either a NORWECO pump vault or a simple grinder pump installation in the septic tank fluids compartment or a BK-2000 filtration unit paired with a standard lift pump unit will give comparable performance and possibly increased reliability. We have seen very few problems with particle clogging.

We recommend adding NORWECO Bio-Gem organic digester or Bio-PERC to the wastewater up-stream to promote solids breakdown to any configuration, including the BioSTEP®. A typical NORWECO pump package would be as noted below:

Typical NORWECO Pump Package

(There are multiple configurations available)

Also, a good option which is robust and similar to the Biomicrobic’s approach is to add a BK 2000 filtration unit to the septic tank outlet, then feed the filtered outlet to the above pump unit. In this case a single liquid pump is adequate since solids are removed and TSS is lowered to under 10 mg/L.

Master Plumbers

A Plumber at work.

Image via Wikipedia

When you have a drainage problem you think of calling your plumber and letting him fix the problem. A few minutes of checking, and hour or two of fixing and that’s that. You don’t normally think about how complicated the life and work of a plumber can be.

Being a plumber is a simple job for some, but being a Master Plumber is a big job. A Master Plumber is a licensed professional who deals with installations, maintenance and repairing of all residential, industrial and commercial plumbing systems. Master Plumbers need to complete courses, get licenses and have expertise in various types of plumbing related work. Imagine a highly toxic plant that deals with gases and liquids of a dangerous nature. Getting that building ready is a very difficult job and all the piping has to be PERFECT. This is not done by the architects or the engineers but by the Master Plumbers.

Becoming a Master Plumber requires a lot of dedication and patience. Plumbers have to go through a lot of actual work experience before they can become Master Plumbers and have to take exams regarding plumbing codes. Because of the difficulty in becoming a Master Plumber many choose to get a general contractors license rather than getting a master plumbers license. This is also why Master Plumbers are more expensive.

Plumbers play a very important role in all buildings. Plumbers are needed in construction of homes, offices and different industries. Because of how technology has also advanced, waste management and water treatment has become a lot more complicated than it once was. Skilled and experienced Master Plumbers are needed to get the job done and have places ready for business or for living.

Master Plumbers are knowledgeable in all plumbing fields but like other professions they can also specialize in different fields. These different fields include:

• Laying pipes

• Fitting pipes

• Designing plumbing systems

• Repairing plumbing systems

• Performing maintenance on plumbing fixtures and even appliances

• Indoor Plumbing

• Outdoor plumbing

• Asbestos Removal

• Roof replacement

• Bathroom renovations

• Gas fitting

• Industry Fire Protection

• Residential sprinkler systems

• Heating, cooling and ventilation

• High rise and commercial sanitary plumbers

• Irrigation

• Metal roofing domestic and commercial new and replacements

• Back-flow prevention

• Drainage and sewer blockages

• Green plumber including solar, hot water products and energy efficient products

• All forms of Industrial fluid distribution system maintenance

Master Plumbers also have to deal with the codes that need to be followed in relation to plumbing systems. Just like architects and engineers who need to worry about building codes being up to standard, the same applies for plumbing.

The new trend that is also becoming more popular is going green. Plumbing too has its green ways. You can look for a Master Plumber who specializes in environmentally friendly plumbing ways in order to be kinder to earth and kinder to your wallets as well!

Things like designing your plumbing in such a way that you save a lot of water will help you with your water bill. Your plumbing system can be designed to reuse water that you’ve already used. Water from your sink can be used to flush your toilet for example. Or heating systems that are designed to save on your electric bill. There are many options; you just need a Master Plumber specializing in Green Plumbing to show you what can be done in your home.

It isn’t necessary to hire a Master Plumber to take care of your homes needs, but having an expert can save you money. Trying to fix things by yourself can result in you spending even more. One wrong move in a pipe can result in a crazy household leak and that I am sure you don’t want to face.

Commercial Wastewater Treatment

One of the first line treatments advised by physicians for constipation may have no pharmaceuticals at all. Rather, he or she will recommend that a patient go on a fiber-intensive diet plan, supplementing regular foods with psyllium or other sources of fiber. Some natural sources may also be suitable depending on whether they contain enough fiber.

A lot of individuals have heard of supplements like metamucil that are fortified with loads of fiber. Metamucil is really a product made by Procter and Gamble, marketed to people who suffer from constipation. But just a little research will show that you will find high fiber foods from entirely natural sources. Prunes, or dried plums, are 1 such instance. Probably the most interesting fact is that prunes contain an additional agent that’s advantageous for treating constipation.

Plums have been a part of mankind’s food source for numerous millennia. Archaeologist evidence shows large quantity of pits in waste sites that go back to ancient occasions. Then as now, the procedure for manufacturing prunes has probably changed fairly little. The plum fruit is harvested from the plant and then arranged in a cool oven structure. The plums are dehydrated at 180 degrees Fahrenheit for a little under 20 hours. The resulting prunes are collected for additional processing.

The chemical makeup of prunes is complex, which is one cause for its multipronged effectiveness as a constipation agent. And although we have sufficiently advanced technology to discern these chemicals, we have but to totally understand the mechanism whereby each chemical aids in laxative activity.

The issues we do understand concerning its anti-constipation properties are two folds. Initial, we know that the high fiber content of prunes means that consuming it assists bulk up foods in the way conventional fiber supplements aid digestion. Two, we also know that prunes contain a lot of sorbitol which is a sugar-like substance that retains water and makes stool softer and as a result faster-moving in the gut.

On top of ingredients with laxative properties, prunes are a high energy supply. The high power is derived from its mix of both simple and complex sugars such as glucose and fructose. Individuals who eat prunes get a quick power boost also as a sustained one from digestion of complex sugars. We also know that prunes contain a great deal of sorbitol which is really a sugar-like substance that retains water and makes stool softer and therefore faster-moving in the gut.

A stream of suggestive evidence shows that prunes include a big quantity of other compounds that aid in health. Phenolic compounds are found in high concentrations and have been linked to enhanced laxative effects, further supporting the use of prunes for constipated patients. Potassium is also in high concentrations. Like bananas, eating prunes might assist reduce muscle fatigue and improve efficiency.

Even though there’s no need to prepare the prunes in a unique way before consuming, a commercial food preparer within the United Kingdom stumbled upon a house recipe for treating constipation that entails blending prunes with other fruits and vegetables. The recipe, known by the name Beverley-Travis, has become well-known as well as studied for its efficacy in enhancing digestive health.
