Here, the feasibility of adding cationic polyacrylamide (cPAM) to alleviate the toxicity of polyvinyl chloride (PVC) microplastics (i.e., 30 mg/g TS) to WAS anaerobic digestion was investigated. As a result, the moderate addition of cPAM (i.e., 3.0 mg/g TS) significantly recovered the methane production from 15.6 ± 1.7% inhibition to 5.8.

What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.

How effective is PAMC flocculation in turbid water clarification?

Chemical and morphology structures of PAMC were characterized and analyzed. Flocculation performance and kinetics were investigated in highly turbid water clarification. Most effective flocculation occurred at pH 4 with the flocculant which contained the highest cationic content.

How cationic polyacrylamide (PAMC) is prepared?

Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.

Does cationic polyacrylamide enhance algal harvest?

Can acryloxy Trimethylammonium chloride and acrylamide be a template copolymer?

Therefore, it is particularly important to develop new and efficient flocculants. In this paper, the template copolymer of acryloxy trimethylammonium chloride (DAC) and acrylamide (AM) was successfully synthesized by microwave-template copolymerization (MV-TP) using sodium polyacrylate (NaPAA) as template.

What is cationic polyacrylamide (CPAM)?

Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
