The commonly used silicone oils include polydimethylsiloxane and polymethylphenylsiloxane. Polydimethylsiloxane is used in paints and inks. Although polymethylphenylsiloxane has good compatibility, it does not have the ability to control surface state, so it is basically not used in leveling agents, and is mostly used for high-temperature resistance

LatviaWhen 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
