What is cationic polyacrylamide (CPAM)?
Cationic polyacrylamide (cPAM), a linear water-soluble and high-molecular polymeric compound with cationic charges, can effectively enhance solid-liquid separation through charge neutralization and interparticle bridging and is widely used worldwide ( Campos et al., 2008; Dai et al., 2014).
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 CPAM is used in sludge dewatering?
It is very significant and valuable to apply CPAM in the field of sludge dewatering and improve the sludge dewatering and conditioning effect. CPAM is mainly prepared by polymerization of AM and cationic monomer. Acryloxy trimethylammonium chloride (DAC) is one of the more commonly used cationic monomers.
Does CPAM adsorption occur on a na-MMT surface?
Understanding the adsorption behavior of CPAM on montmorillonite (MMT) surfaces is of great significance in explaining the excellent performance of cationic inhibitors. In this work, molecular dynamic simulations (MD) are applied to investigate the adsorption mechanism of CPAM on the Na-MMT surface.
