Aeration element for the gasification of liquids

摘要

An aeration element for gasification or aeration of liquids includes an essentially flattened, rigid support element having a substantially oval cross-section and corrugated outer surfaces, the corrugated outer surfaces including ridges defining grooves therebetween; a threaded opening for receiving a cooperating fitting for connection to an air supply; and a flexible membrane of elastomeric material disposed around the support element, The membrane has a plurality of slits, and wherein compressed gas is introduced between the support element and the membrane, the gas can escape via these slits into the surrounding liquid. A retaining clamp holds the membrane around at least one end of the support element. A check valve assembly prevents backflow of liquid, particles, sludge or debris into the interior of the support element.

1. An aeration element for gasification or aeration of liquids, comprising:
a rigid support element having flattened, oppositely disposed, corrugated outer surfaces and an oval cross-section, wherein said oppositely disposed corrugated outer surfaces define at least one chamber therebetween and have at least two ridges defining grooves therebetween; a threaded opening for receiving a cooperating fitting for a sealed connection to an air supply; a flexible membrane disposed around said support element, said membrane having a plurality of slits disposed therein, and wherein compressed gas is introduced between said support element and said membrane and can escape via slits into a liquid that is to be gasified; and at least one retaining clamp for holding said membrane around at least one end of said support element.
