Abstract
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.
Claims13
A method for cleaning diffusers in an aeration system comprising:
- a) transporting a liquid acidic solution into a downcomer pipe and/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;
- b) allowing the liquid acidic solution to vaporize;
- and
- c) blowing the vaporized acidic solution into a plurality of diffusers supported by the air distribution pipes,
- wherein the liquid acidic solution is transported into the downcomer pipe and/or purge line in an amount sufficient to fill 40% or less of the total volume of each individual air distribution pipe.
