There is no unified understanding of the mechanism of defoaming agents. According to the mechanism of defoaming agents proposed by predecessors, there are generally the following types: [4]
General defoaming mechanism
Typical defoaming mechanisms with a broad overview are the Robinson defoaming mechanism and the Ross hypothesis. Among them, Robinson mechanism is the basis of Ross hypothesis, which mainly emphasizes the liquid drainage of defoamer destroying foam and Marangoni effect to realize defoaming; The Ross hypothesis is based on the fact that the defoamer particles are insoluble droplets, while some defoamers actually produce defoaming effects in a dissolved state, so the defoaming mechanism of the Ross hypothesis is not comprehensive

DominicaWhen choosing Free of silicone defoamers for aquaculture wastewater treatment, let's first see what kind of foam in wastewater belongs to, which is usually divided into chemical foam and biological foam. Chemical foam is also divided into active agent foam and oil and suspended solids foam. Active agent foam: when detergent, colloidal organic matter and other surfactants or other foaming substances are present in the sewage, under the conditions of water flow speed, fall, aeration, blowing off, etc., a large number of small and light white brown unstable foam will appear on the water surface. This kind of wastewater is a high molecular synthetic substance with poor biodegradability, which is a problem in sewage treatment. Biological foam: It is generally earthy brown or grayish brown, and there are many reasons for this kind of foam, so it is difficult to deal with. With the defoamer for aquaculture wastewater treatment, it is not necessary to consider whether it is suitable or not. This defoamer has strong versatility and can adsorb surfactants and change the hydrophilicity of surface activity. After dilution and regulation, it can enter biochemical treatment, which can solve the problem of chemical foam or biological foam. Quotation

Dominica The antifoaming agent for aquaculture wastewater treatment is Free of silicone defoamersfor the aquaculture wastewater industry system. It can quickly disperse in water, is easily soluble in water, is not easy to break emulsion and float oil, and is fast in Free of silicone defoamers and long in inhibiting foam. It does not change the oxygen content of water quality or the microorganisms in the water, and has good acid and alkaline resistance, wide application range, and good chemical stability.
