Antifoams & defoamers

Antifoams & Defoamers

Antifoams and defoamers do exactly what the name suggests – i.e they reduce or eliminate foam. If left, the foam is not only unsightly but also leads to lower process efficiencies.

Foam can be generated in many systems including, boilers, cooling towers and effluent treatment plants. It often arises from the use of surface active chemicals in the water system which stabilize bubbles within the water leading to the formation of foam. The antifoam agents displace these surface active chemicals which leads to the bubbles breaking and hence the reduction of the foam.

Antifoam agents are typically either silicone or hydrocarbon based. We can supply products based on either. The optimum product choice will be determined by the application.

Product code Application Composition Benefit
BV1 Steam boiler water antifoam Based on polyalkylene glycol. Acts at the water/steam interface to control foam generation. Concentrated low dose rate product
BV2 General purpose antifoam which can be used in many diverse areas of water treatment. Mineral Hydrocarbon Versatile antifoam which can be used in open cooling, process water and waste water treatment applications. Low dose rate, long lasting antifoam
BV7 Food grade antifoam food grade silicone Non-ionic emulsion. Excellent foam control in a wide range of food processing applications
BV8 General purpose and acid descaling mineral hydrocarbon. An excellent foam control agent for use in many aqueous systems. It is particularly useful in controlling foam during acid descaling processes.
