Flocculant - an overview | ScienceDirect Topics

The organic flocculants are more expensive on a unit-weight basis than the inorganic flocculants in general use, but the required dosage is much lower. The organic flocculant for OMWW must have cationic properties on account of the charge on the surface of the colloid particles; it must also have non-toxic and non-polluting properties to be used later as inter alia feed for animals or fertilizers.

Nonionic polymeric flocculants with low charge density might be no match for PAC and FeCl 3. When WAS is pre-oxidated, the MC of the sludge cake could be reduced to below 80 wt% through further treatment with inorganic coagulants, whereas using PAM alone cannot achieve this due to its low charge density ( Chen et al., 2016b ).

polyacrylamide

Polyacrylamide

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide..
