Is acrylamide a cationic flocculant?

The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .

Who bought polyacrylamide flocculant?

Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).

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 .

Does cnpam flocculant have a good universality for high turbid water?

The fractal dimension analysis indicated floc size increased with the enhancement of the CNC content in the CNPAM flocculant. It was testified that the flocculant had good universality for high turbid water in different concentrations and with the presence of various inorganic salts.

Does cationic monomer content affect flocculation performance?

Evaluation of flocculation performance showed that PAMC had much higher turbidity removal efficiency under acidic conditions, and their optimal dosage decreased with increased cationic monomer content.

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.
