Abstract
Alum contained dominantly the monomeric aluminum species, and PAC contained the polymeric aluminum species. Both Alum and PAC has been improved removal of TP with increasing coagulant dose. Coagulant used directly influenced the microbial activity. Impact on microbial activity, the PAC was smaller than Alum. And impact on microbial activity and population according to the return sludge appeared to be minor.
