Antifoamers for Clean Water

Except some cases (like in coal industry) foaming in general is undesirible. Some samples where foaming is problematic: Sugar industry, paper industry, paint industry, phosphorus acid production, waste water treatment plants (aerotanks). Normally clean water doesn`t form stable air bubbles. When there is in water some dissolved or non-dissolved chemical substances air bubbles dispersions can be formed and foam starts formation under water.
