Seeing as nobody has added a reply for the last 11 months I'll give my two cents. From what I have read years ago about Alum conditioning, is that instead of using Polymers and such, Alum was preferable choice and used for Coagulation and Floculation then Anaerobically Digested and dried to produce a  class A Biosolid that was pelletized,bagged and sold for fertilizer. Seems to me this method may have been used in Europe somewhere.
