Transfer and degradation of polyacrylamide-based flocculants
These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound. This review focuses on the mechanisms of transfer and degradation, which can affect both PAM and residual AMD, with a special attention given to the potential release of AMD during PAM degradation.，Polyacrylamide (PAM)?
Polyacrylamide PAM is currently the most widely used synthetic organic polymer flocculant, and sometimes it is also used as a coagulant aid. The raw material for the production of polyacrylamide is polyacrylonitrile CH2=CHCN. Under certain conditions, acrylonitrile is hydrolysed to produce acrylamide, and acrylamide is then subjected to，Chemistry, Biochemistry, and Safety of Acrylamide. A Review Polyacrylamide has found numerous applications as a soil conditioner, in wastewater treatment, in the cosmetic, paper, and textile industries, and in the laboratory as a solid support for the separation of proteins by electrophoresis.

Best Practices Guidance for the Use of Anionic Polyacrylamide
Largest TSS reductions observed in polymer systems on Sept. 9 (88%) and Dec. 4 (95%). Polymer systems were capable of reducing TSS concentrations to below 25 mg/L. Polymer tank system with the sediment bag achieved largest TSS reduction (95%) and lowest effluent TSS concentration (13 mg/L). For controls, effluent TSS consistently >25 mg/L,The Precautions for the Use of Anionic Polyacrylamide Pam The Precautions for the Use of Anionic Polyacrylamide Pam. 1. Configuration concentration. The molecular weight and viscosity of anionic polyacrylamide pam are high, so the ratio concentration is generally between 0.1% to 0.5%, and the solution ratio concentration can also be adjusted according to the specific situation on site. 2.
