Natural flocculants from fresh and saline wastewater
The flocculation performances of the 4 EPS fractions and synthetic PE A120V toward saline kaolin suspension is given in Fig. 6a. The synthetic PE A120V showed maximum flocculation efficiency (98.6 ± 0.1%) at a concentration of 0.1 mg/g kaolin (corresponding to 0.5 mg/L kaolin suspension), but a reduced efficiency at higher concentrations.

Degradation and transfer of polyacrylamide based
The potential risks on environment and health are thus linked to the spreading of acrylamide and polyacrylamide degradation products in the natural environment. Two levels of spreading have to be considered: The water: about 95 % of the polymers adsorb on the particles during flocculation stage.
Acrylamide is a colorless, odorless, crystalline amide that polymerizes rapidly and can form as a byproduct during the heating of starch-rich foods to high temperatures.Acrylamide is used in the production of polymers mainly in the water treatment industry, pulp and paper industry and textile treatment industry and is used as a laboratory reagent. . The polymer is nontoxic, but exposure to the

- 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 .
- 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 .
- 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 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.
