Antifoamers
Foam may be produced and sustained during effluent processing, when surfactants are present that lower surface tension, and/or contain other materials that reduce drainage of water from bubble walls. Effluents may thus be broadly grouped into 3 types dependents on their source:
a) Industrial: high foaming "synthetics", such as from detergents, soaps, emulsifiers, sanitises etc.
b) Industrial: foam stabilising "natural" materials such as from starches, proteins, fibres, cellulosics, and other long chain polymers.
Municipal: highly diluted mixtures of surfactants. Also digested slurries containing less active foaming species. Foam may occur wherever air is introduced into the effluent, or gas evolved from it. Minimising the free fall of liquid from pipes or weirs etc. reduces minor aeration, but the nature of certain processes inevitably creates conditions to generate foam, that may require control or inhibition
Foam makes problems in variuous industries and applications:
- Sugar industry
- Dairies
- Fermentation processes
- Vegetable processing
- Paper manufacture
- Activated sludge processes
- Primary mechanical aeration
- Other processes
- We offer wide range of antifoamers. Please, contact, for more information.
