Unveiling the mechanisms of how cationic
2019-5-15 · 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). In WWTPs, cPAM is usually used in chemically enhanced primary sedimentation, leading to cPAM …
