    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.In the cross-linked form, the possibility of the monomer being present is reduced even further.

    However, by the addition of anionic polyacrylamide (PAM) it was possible to boost the coagulation capacity and removal efficacy of PE particles (d < 0.5 mm) from 13 to 90.9% (see Fig. 10b). This was possible due to the dense floc formation and high adsorption capability of Fe-based flocks (positively charged) under neutral conditions.
