Silicone Antifoam

Antifoam materials help achieve washing effectiveness by preventing entrapped air from forming in the system, which allows for an easier, unrestricted flow of filtrate through the screens and washers.

Antifoam agents either decrease the surface tension or alter the dispersion of solids or both. They must also be insoluble in the foaming system. Usually, small concentrations (< 0.1% bwow) can provide sufficient foam control.
