The causes of foam in a wastewater treatment plant are varied. In secondary treatment systems, foam is typically caused by biological activity. However, foam can also be caused by mechanical action and chemical contamination. Surfactants in the influent or in some polymer treatments can also cause foam. Regardless of the cause, foaming in secondary treatment and final effluent areas can result in a variety of environmental, health and safety issues.
Antispumin defoamers comprise a range of proprietary products that effectively control foam and entrained air in municipal wastewater systems. In addition to collapsing or breaking down existing foam, Antispumin defoamers remain on the water’s surface to prevent the formation of future foam. Common application areas include the activated sludge process, aerated lagoons and plant outflows.
