I'll try to answer your question in a few lines: Aluminum salts such as alum and polyaluminum chloride (widely available under different trade names) are coagulants not types of coagulants are ironbased: ferric chloride, ferric sulfate, ferrous sulfate.
Since the iron waste stream is about onefifth the volume of the aluminum sulfate stream, this level of aluminum amounts to pct of the aluminum fed into the system. The amount of soluble organic material present in the aqueous exit streams was determined from this test by collecting the organic material by filtration through activated charcoal.
