This is a great example of the power of the AWC membrane cleaners. This membrane was removed from a ground water treatment plant and expected to be disposed of. Our analysis showed it caked in a thick layer of biological fouling as well as aluminium, calcium (most likely calcium phosphate), iron, silica. Basically a bit of everything.
The AWC C-227 caustic cleaner which is our most powerful caustic cleaner broke down the biofouling and dispersed some of the insoluble inorganics present. This left a slight iron residue on the surface that the C-217 iron cleaning reagent then removed.
The result is a perfectly clean membrane that was as close to new as you can get.
