Acid wastewater containing iron
Safe acid etching of aluminum
Safe acid etching of aluminum

23/1/2012, · Aluminum salts are used in water treatment and wastewater treatment, so I see no problem in flushing it as long as you are talking a small quantity from an artist, not an industrial quantity. The aluminum may be impure, and release some copper or other metals in the precipitate, but again I think this will be very minor -- in the same range as from scrubbing a copper bottomed pot.

This dosage decrease with ACH is also due to its charge characteristics. Some of the ,aluminum, metal in ACH is more cationic (more positively charged) than that in alum or PACl. The increased charge lets ACH work at lower metal dosages, further lowering chemical solids generation and ,aluminum, residual levels in finished water. Bridging the gap
