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.
