DIFFUSED AERATION SYSTEMS AND METHODS FOR CLEANING FOULED DIFFUSERS IN AERATION SYSTEMS

摘要

A method for cleaning and preventing diffuser membrane fouling of an aeration system can include: transporting a liquid acidic solution into a downcomer pipe or a purge line positioned in a reservoir of an aeration system containing a body of water such that the liquid acidic solution flows into a manifold and air distribution pipes; allowing the liquid acidic solution to vaporize; and blowing the vaporized acidic solution into a plurality of diffusers supported by the air distribution pipes. An aeration system that can implement the method is also included.
