Glycol Antifoam for Wastewater Treatment

EO/PO based defoamers

EO/PO based defoamers contain polyethylene glycol and polypropylene glycol copolymers.

They are delivered as oils, water solutions, or water based emulsions.

EO/PO copolymers normally have good dispersing properties and are often well suited when deposit problems are an issue.

a high performance glycol based antifoam and defoamer scientifically formulated for use in secondary treatment or final effluent in a wastewater treatment plant.

it will rapidly reduce existing foam and can also be used as a defoamer.

it is effective over a broad pH range.

DO NOT use for potable drinking water.
