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 stabilise 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.
