FIELD: water treatment.
SUBSTANCE: aerator contains perforated membrane 1 and pressure pipe 2. Surface of membrane 1 is made corrugated with aeration holes on the upper protrusions of the corrugations and lower holes for removal of deposited contaminants in which inclined elongated walls 3 are formed in a lower part of the folds of corrugated membrane 1. Pressure pipe 2 is made with the possibility of supplying air to the aeration holes.
EFFECT: invention allows to increase the degree of wastewater treatment.
