Water treatment plants create foam which needs to be suppressed to maintain efficiency. Both silicone and non-silicone antifoams can be used to either knock down foam after build up or as an additive to reduce the initial build-up of foam. Product selection depends very much upon the pH value, temperature, water and the concentration or dosing requirement.
CHT antifoams are available either as high percentage concentrated products for pre-dilution or ready to use solutions.
Non-silicone antifoams are particularly useful for use in biological plants where the use of a silicone may interfere with the growth of desirable bacteria.
