Description
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 Parvicella, Nocardia, 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, an enzyme product that specifically attacks the fats, oil, grease, and fatty acids that filaments use for food.
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.
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 enzymes. 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 enzymes 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.

Foam Buster Applications
- Oxidation Ditches
- SBRs
- Extended Aeration Wastewater Treatment Plants
- Aerobic Digestors
Foam Buster Benefits
- Reduces and eliminates foam
- Reduces sludge and scum production
- Eliminates negative impacts from incoming fat, oil, and grease
- Improves settling
- Increases good bacterial populations
- Lowers effluent BOD and TSS
- Degrades surfactants and emultions
Dosage Rates:
Nocardia
| Recipe for Nocardia Removal |
| 1.) Waste solids 20-30% (Example: if MLSS is 3000, waste to 2100-2400 ppm) |
| 2.) Add Qwik-Zyme L to the head of the plant (Double dosage if possible). This will heavily break down FOG for the bacteria to easily digest. |
| 3.) Add Foam Buster to the head of the plant or aeration basin (Double dosage if possible). This will activate and stimulate the bacteria to specifically break down FOG that is feeding the Nocardia. |
| 4.) Keep MLSS low for 2-3 sludge ages |
| 5.) After, rebuild the biomass |
| (Optional: Add Bug On A Rope to lift stations to start the FOG degradation process sooner) |
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
By 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.
Brewery
Challenge
A brewery had a yeast outbreak and it caused bad foaming, poor settling, and bad effluent. The problem persisted for a couple of months until they called us.
Solution
Add 2# – 3# Foam Buster to help with the foam and add 1 gallon of Qwik-Zyme P to improve settling.
Results
After experimenting with the dosage rate we were able to come up with the perfect solution. Just one day after adding Qwik-Zyme P the plant settled perfectly and the customer was ecstatic.
