DeFoam 3000 – Fast-Acting Defoamer

(2 customer reviews)

Wastewater Defoamer Designed for Biological Plants

DeFoam 3000 is a 100% concentrated defoamer, formulated to rapidly deflate foam by creating a monomolecular film. This film spreads across the water surface, quickly collapsing foam. DeFoam 3000 does not contain any emulsifiers, making it safe and effective in biological wastewater processes. It can be used in aerobic or anaerobic processes, wherever foaming is a concern.

Because Defoam 3000 is ultra concentrated, it works at low dose rates and is long lasting. It is relatively insoluble in water, keeping it in contact with the foam at the surface. It can be fed with a small chemical metering pump, sprayed over the surface, or dumped right on the surface.

Unlike a silicone defoamer, Defoam 3000 will not disperse or disrupt wastewater biology. It is formulated specifically for use in biological systems, including wastewater treatment plants, dairy, food processing, and refinery systems, as well as manure pits.

Not a Silicone Defoamer!

Industrial defoaming agents are often silicone-based, and we strongly recommend against them in biological systems. The silicone formulas are harmful to bacterial life, and interfere with settling. Silicone anti-foams break down into siloxanes, which corrode combustion engines and dismantles the biomass. DeFoam 3000 does not contain silicone, and works with your wastewater plant’s biology.

DeFoam 3000 is a highly effective and concentrated anti-foam solution formulated specifically for use in aerobic and anaerobic wastewater treatment processes.  Our product 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.

The table below gives a clear breakdown of the differences between a silicone defoamer and biologically-based DeFoam 3000.

  1. Kyle J. (WI)

    Works great nocks foam down fast

  2. Jacob N. (ID)

    We use the foam and manure digester because we were constantly having form events ever since introducing defoamer with a dosing pump our foam events have been I’ve been cut by 90%.
