Filament Buster - For Bulking Filaments

Filament Buster - For Bulking Filaments

Filament Buster reduces the levels of bulking filaments Type 021N, Thiothrix and Type 0092. It is a specific source of amino acids and micronutrients. Typically, these filaments cause bulking in wastewater systems with nitrogen deficiency and lead to dewatering issues. They can be present on an ongoing basis, during times of seasonal temperature changes, or as a result of getting dumped on by upstream sources.

This product is specifically designed to combat filaments caused by nitrogen deficiency.

The Science Behind It

Filament Buster is added to the aeration basin of various types of activated sludge processes including:  SBRs, oxidation ditches, extended aeration wastewater treatment plants, as well as MBBR and MBR treatment plants. In addition to municipal waste streams, it works great for balancing high sugars in the juice and beverage industries.

Filament Buster works by providing floc forming bacteria the amino acids and micronutrients they need to out compete bulking filaments Type 021N, Thiothrix and Type 0092.

Thiothrix/Type 021N:

Thiothrix-Type-021N-1
Thiothrix/Type 021N are thought to be different forms of the same filament. Thiothrix tends to be more observed in low DO, septic and sulfur reducing conditions. Type 021N is more prevalent in nitrogen deficient conditions.

Thiothrix/Type 0092:

Thiothrix-Type-0092
Type 0092 can cause bulking problems in aerobic wastewater systems but is an important precursor to foaming caused by M. Parvicella. Type 0092 thrives in conditions with very similar food sources to M. Parvicella but in warmer weather conditions.

The Science Behind It

Traditionally when wastewater plants have these filaments they may use a simple form of nitrogen, like urea.  The nitrifying organisms and the floc forming bacteria are in competition for the ammonia in the form of urea. The amino acids and micronutrients in Filament Buster are metabolized more directly by floc forming bacteria, will limit exocellular polysaccharide sliming (EPS) and produce better settling.

In industrial wastewater plants trying to balance BOD:N:P ratios where they get high BOD loadings in the form of a carbohydrates, Filament Buster creates less D.O. demand than traditional urea.  In addition, by addressing the nitrogen deficiency in a fundamental way a plant will produce less sludge.

Compatible Products

This product functions best added daily to the first section of the aeration basin in an aerobic wastewater system.  Filament Buster works well in combination with: Qwik-Zyme L, Qwik-Zyme P and OxyFresh depending on what waste stream it is being added to and what filament needs to be controlled.

Foam Buster – For Foaming Filaments

Foam Buster – For Foaming Filaments

Foam Buster, our best foam-fighting technology, is a blend of specialized proteins, free amino acids, and micronutrients which stimulate the floc-forming bacteria to degrade grease, emulsions, and petroleum hydrocarbon-based products and enable the bacteria to outcompete the filaments which cause foaming. Foaming filaments like NocardiaGordonia amare, and Microthrix parvicella use the fat, oil, and grease as well as their fatty acid by-products to produce a buoyant fatty cell wall. Foam Buster provides the naturally occurring bacteria a chance to compete.

The Science Behind It

The Science Behind It

Foam Buster is effective in the oxidation ditches, activated sludge plants, SBRs, extended aeration waste water treatment plants, and aerobic digestors. All these areas can be infiltrated by Foam-causing, F.O.G.-hungry filaments like Microthrix ParvicellaNocardia, and Type 1863. Foam Buster also works well on the bulking filaments Type 021N and Type 0092.

Foam Buster’s control of these filaments can be supported by heavy wasting programs and Qwik-Zyme L, a biocatalyst that specifically attacks the fats, oil, grease, and fatty acids that filaments use for food.

Foam Buster Reactions

Even More Than an Energy Drink

Most bacteria in wastewater plants are unmotivated and listless. Part of Foam Buster’s micronutrient blend is formulated to give the filament-degrading bacteria extra boosts of energy that allow them to degrade the filaments faster than they can reproduce and get rid of the foam. As the graph shows, Foam Buster allows wastewater bacteria to degrade filaments while contributing a much lower amount of their own energy.

But Foam Buster supports filament degradation in more ways than energy. Its formula also contains nutrients specifically needed by the bacteria to create certain foam-busting biocatalysts. A bacon grease molecule is different from a butter molecule is different from a filament molecule, and Foam Buster provides the right array of micronutrient ingredients to allow the bacteria to produce the specialized recipes for biocatalysts to attack these different molecules.

Settling Issues Solved

Foam Buster also contains minerals, surface-tension depressants, and natural buffering systems, all of which work together to rid your plant of surfactant and emulsion chemistries as well as F.O.G. and fatty acids.

Not a Band-Aid©

A lot of times when a wastewater plant gets foam they will use a chemical defoamer or an anti-foam to knock the foam down. Chemical defoamers work by covering up the problem for a period of time. In addition chemical defoamers can cause sludge bulking issues, nitrifier toxicity, and are limited in that they do not control Nocardia or surfactant foams. Silicone anti-foams break down into siloxanes which corrode combustion engines. Neither type of product truly addresses the root cause of the problem.

Foam Buster addresses the cause of the foam and provides bacteria with the tools they need to digest and break it up. And because you never know when an influx of grease or surfactants can hit, Foam Buster has a maintenance dose to keep your bacteria crisis-ready and we offer DeFoam 3000, which is an organic defoamer that is easy on the biology and functions as a fast-acting temporary fix. For especially tough issues, use the synergistic combination of Foam Buster and Qwik-Zyme L. Qwik-Zyme L helps to get the grease under control while Foam Buster alters the bacteria populations so the foam will not return.

A municipal wastewater operator was called down to the plant at 1 a.m. on a Saturday to find 6 feet of foam on the basins. A company had rinsed out 5 gallons of surfactant out of an old barrel with no idea how it was going to foam in the wastewater plant. The company apologized, only to repeat the same mistake six months later. This time the plant knew the culprit.

Foam Buster Case Studies

Nocardia Foam

Challenge

A wastewater treatment plant on the south side of Chicago had an extensive foaming issue caused by the Nocardia filament.  All the aeration basins were completely covered, and the foam even found it’s way into the center walls of the clarifier.

1.1 MGD Activated Sludge Municipal Treatment Plant Incoming BOD: 140-160 ppm Incoming Ammonia: 15-20 ppm ; with random spikes up to 60 ppm

In addition to the foaming, the plant received exceptionally high spikes of ammonia during the weekends.  These spikes would reach up to 60 ppm.

Solution

The operators began applying Foam Buster and Qwik-Zyme L to improve the cold weather degradation of surfactants, grease, and long-chain fatty acids, all which are nutrients for Nocardia.

Results

Nocardia-Foam-Before-AfterBy the 30th day of the application, the foam cleared up to 75%.  The operators continued a maintenance application to fully clear the plant.  By fully degrading the grease and fatty acids, more ammonia and nitrogen was consumed, thus stabilizing the weekend ammonia spikes.

Another Piece to the Puzzle

This plant’s operator got a tip from a nearby neighbor about suspicious activity, after putting two and two together the operator notified the authorities.  It turns out, in this nice community, a resident was producing methamphetamine.  As soon as this meth lab was shut down, the wastewater plant stop receiving ammonia spikes.  Aquafix is able to help out with spikes, but the production of methamphetamine will send very high amounts of ammonia and other chemicals to your plant.  It is unfortunate, but highly important to keep a watchful eye.

Oxidation Ditch

Challenge

A wastewater plant in Western Pennsylvania has a flow rate of 3 million gallons per day. During the winter months they routinely encounter problems with foam.

Solution

March 1, 2011 they began adding 20 lb. of Foam Buster per day.

Results

3 weeks later: The foam was gone and the temperature of the aeration basins was 75°F.

SBR

Challenge

A customer in central Alabama has a SBR system that was having an ongoing issue with Microthrix Parvicella. It was causing bad foaming, poor settling, and a cloudy effluent. This plant was out of compliance and needed immediate help. Their flow rate was 100,000 GPD.

Solution

They added 10 lbs. of Foam Buster and 1 quart of Qwik-Zyme L per day for 7 days.

Results

7 days later: Grease was cut in half and settling had improved. 21 days later: The foam was gone and the plant was in compliance with the super tight limits.

DeFoam 3000

DeFoam 3000

DeFoam 3000 puts a monomolecular film across the surface of foaming basins that reduces the surface tension of the foam, knocking it down. This product is formulated for biological systems. Unlike silicone-based industrial defoamers, DeFoam 3000 won’t disrupt bacterial floc and works at low dose rates.

The Science Behind It

No Silicone Needed!

DeFoam 3000 is a highly effective and concentrated anti-foam solution formulated specifically for use in aerobic and anaerobic wastewater treatment processes.  Silicone anti-foams break down into siloxanes, which corrode combustion engines and dismantles the biomass.  DeFoam 3000 knocks down foam, while being safe for biological processes, as it contains zero emulsifiers or silicons and won’t harm bacterial life or interfere with settling as it breaks down your toughest foam.  The all natural essential oils blended in give the product a sweet aroma and longer lasting abilities compared to chemical and silicone defoamers.

Using DeFoam 3000 on Microthrix Parvicella?  Couple it with Foam Buster or Qwik-Zyme L for maximum impact.  These two take-no-prisoner formulas digest grease and cut off its food source.

Qwik-Zyme L

Qwik-Zyme L

Qwik-Zyme L is an excellent product for grease control in sequencing batch reactors (SBR), wastewater treatment plants, equalization tanks, and food and egg processing plants.

It is the top-of-the-line pump station grease degrader.

This is not a bacterial product, but rather a high tech saliva. This means that Qwik-Zyme L incorporates three types of lipid degrading biocatalysts to provide dramatic hydrolysis of fat, oil, grease (FOG) and resulting fatty acids. Qwik-Zyme L will degrade the FOG, and your bacteria will eat it.

Qwik-Zyme L can degrade a range of fatty acids such as oleic, steric, palmitic as well as fish oils, triglycerides, milk, and animal fats.  No more grease, no more foam, and no more backups.

See how it works

The Science Behind It

Why is it so important to control fats, oils and grease?

degrade grease lower COD

Qwik-Zyme L was tested against a control for a customer with COD issues. This testing showed a sharp decrease in COD when using Qwik-Zyme L, while the control was essentially at the same level after 4 hours. The control did see an initial increase in COD due to COD chains separating but not degrading and giving the appearance of more COD.

In the winter months, when water temperatures are colder, the naturally occurring bacteria cannot completely break down FOG and the fatty acids that build up in the wastewater plant. These fatty acids are then taken up by filaments like Microthrix Parvicella and Nocardia which allows them to float and foam. Qwik-Zyme L breaks up these fatty acids and cuts off the filament’s food source. It’s fascinating science for wastewater operators.

Qwik-Zyme L – Grease Degrader works well with VitaStim Low F:M and Foam Buster and is used in all types of municipal and industrial applications. For especially tough issues, use the synergistic combination of Qwik-Zyme L and Foam Buster. Foam Buster alters the bacteria populations so the foam will not return while Qwik-Zyme L helps to get the grease under control.

High Lauric and Stearic Fatty Acids

Solution

Qwik-Zyme L, VitaStim Surfactants

Results

An organic chemical manufacturer in North Carolina contacted us about foam being generated in their treatment system. They use a series of two lagoons, with high aeration in the first lagoon to pretreat their waste stream before sending it to the municipal wastewater treatment plant. The waste stream has high concentrations of lauric and stearic acids which contribute to influent BOD 600 ppm, and COD 200 ppm. The system was not achieving complete breakdown of these fatty acids as the waste stream moved quickly through the system. The operator began using VitaStim Surfactants to add new bacteria cultures which break-down of fatty acids. This improvement was enough to make the customer happy, but we thought that adding our Qwik-Zyme L, liquid biocatalyst product, would help break down the fatty acids even more quickly. The biocatalyst accelerated the process, a huge benefit in this waste stream with a short detention time. The combination of biocatalyst and bacteria brought the systems effluent waste stream down to BOD 8.1 ppm, and COD .4 ppm.

Flow Rate

120,000 gallons per day

Background

The municipality upgraded their wastewater plant three years ago with fine bubble aeration. Immediately they began noticing a foot of foam on the basins and persistently higher effluent ammonia numbers. They traced the foaming issue down to a tannery in town. The tannery has an existing wastewater process of their own consisting of an equalization tank followed by aeration and a very simple DAF unit. To clean the fat, oil and grease off hides the tannery uses surfactants, substances similar to soap in their make-up. We learned the cause of the issue in the municipal plant was that surfactants were passing through the tannery system undigested, and then foaming when they hit the fine bubble diffusers at the municipal system. The tannery experimented with a number of surfactants to help stop the foaming, but to no avail.

Solution

The solution was to breakdown the surfactants at the tannery’s treatment plant. We had them increase the holding time in their EQ tank to create anoxic conditions and then they added Qwik-Zyme L and Qwik-Zyme P to speed the breakdown the grease and long chain fatty acids. The process was further enhanced by adding Foam Buster to the aeration tank. Foam Buster’s micronutrient blend boosts the ability of native bacteria to degrade fatty acids and grease. The biocatalysts kicked off the surfactant degradation process, and native bacteria with the help of Foam Buster finished the process. Immediately, the city noticed 95% less foam and better settling. As the foam went away they also realized that the surfactants had been knocking out their nitrifiers. As the surfactants were no longer hitting them as they had before, nitrification improved and their effluent ammonia dropped. Now both the municipality and tannery are happy.

Malfunctioning DAF-caused foaming in Aeration

Background

To achieve their effluent goals, this processor has to incorporate 2 pretreatment steps before the waste stream gets to their aeration basin. First a trickling filter takes the BOD from around 4000 ppm to 1000 ppm. Next a Dissolved Air Floatation (DAF) unit removes all the grease that the trickling filter didn’t remove. Trickling filters are notorious for allowing grease to pass right through them. They system generally worked pretty well, but was dependent on the DAF making up for the shortcomings of the trickling filter. However, one day a mechanical issue resulted in the DAF being taken offline, and the timeline for getting the replacement part was unknown. With only the trickling filter for pretreatment, and no other way to remove the fats, oils, and grease (FOG) they soon began foaming.

Solution

This customer started with our fatty acids analysis to determine what the concentrations of FOG were, and which fatty acids it consisted of.

DAF-caused-foaming-aeration

Fatty Acid Testing revealed especially high amounts of Palmitic, Stearic, and Oleic acid. Also typically the highest concentration Fatty Acids in municipal influent.

Since the loss of the DAF, total fatty acids in aeration had now jumped up to 7551.5 ppm. The fastest way to reduce the foam was to accelerate the degradation of the very high FOG in the basin. The most prevalent long chain fatty acids are also typically slow to degrade molecules in an aerobic system. The operator used Qwik-Zyme L at a rate of 2 quarts per day, combined with our VitaStim bacteria blend. The biocatalysts in Qwik-Zyme L act on specific structures in the FOG, which allows bacteria in the system to quickly degrade the FOG molecule. Within 30 days the foam had disappeared, despite the DAF unit still not being brought back online.
