polyacrylamide pam flocculants water treatment industrial use
high molecular weight polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity improver, among other applications.
role of polyelectrolytes in the treatment of water for free sample,according to their ionic charge, polyelectrolytes have been classified into four different categories. cationic and anionic polyelectrolytes are more commonly used in water treatment. polymers with no charged group are known as non-ionic polymers. literature review reveals that polyampholytes have very little utility for water treatment (bratby
recent achievements in polymer bio-based flocculants for low cost
mishra et al. proposed graft copolymerization of starch (st) and polyacrylamide (pam) in the presence of ceric ammonium nitrate as an initiator (generating free radicals under microwave radiations). the obtained grafted starch (st-gpam) exhibited a higher intrinsic viscosity of the polymer, which increased flocculation efficacy.
differently charged polyacrylamide (pam) significantly,lab-scale experiments of ballasted flocculation were performed by using a programmable standard jar-test system (ta6-2, wuhan, china) equipped with six sets of 1-l cylindrical beakers (112 mm diameter and 155 mm height) and identical paddle impellers (50 mm width, 40 mm height and 1 mm thickness).
transfer and degradation of polyacrylamide-based flocculants
this review summarizes the literature which gives information and scientific data on the fate of pam-based flocculants in hydrosystems. pam and associated amd have been considered, and three main families of phenomenon have been investigated: transport, adsorption, and degradation.

- Does polyacrylamide biodegradation accumulate acrylamide monomers?
- The biodegradation did not accumulate acrylamide monomers. Based on the SDS-PAGE and N -terminal sequencing results, the PAM amide groups were converted into carboxyl groups by a PAM-induced extracellular enzyme from the aliphatic amidase family.
