Abstract:
A gasification device for the introduction of air into waste water, comprising:at least one blower body element having a perimeter, a vertex of said perimeter, and a bottom of said perimeter opposite said vertex, in an installation position; a gas distribution groove at said bottom of said at least one blower body element; a membrane surrounding said at least one blower body element and made of an elastic material, wherein said membrane has perforation slits for the introduction of the air into the waste water; and a longitudinal area of said membrane at said vertex of said perimeter of said at least one blower body element, and having an impressed camber radius, which is smaller than the mean camber radius of said membrane, measured in the state as mounted on said blower body element, and features a camber directed outwards, related to said blower body element; wherein disconnecting an air feed and imposing hydrostatic pressure of waste water, force the creation of an axial fold of said membrane at said vertex, which is free of perforation slits.
