WebVarious polymeric flocculants were tested. The higher the molecular weight, the better stronger flocs were produced. Flocculants with more charge also produced better sludge at lower dosages. Granular flocculants always outperformed emulsion flocculants. When high dosages of cationic flocculant had to be used (60-100 mg/l), better results WebDec 12, 2024 · For flocculants, cationic polyelectrolytes are usually favorable because most water and wastewater impurities have negative charges [28,59]. In addition, being water soluble and having a high molecular weight (MW) with a low fraction of charged monomer units are the most prominent characteristics of flocculants .

WebNaCl, the flocculants assumed a coiled conformation, and further coiling was observed in the presence of small quantities of CaCl2 (0.001 mol/L). There was a decrease in intrinsic viscosities at high pH (~8.5 and 10.5) that was merely attributed to an increase in ionic strength with the increase in concentration of Na+ at high pH. WebAfter the destabilization of the colloidal suspension by coagulant, the flocculant with its high molecular weight encourages fast settlement, according to Stokes’ law. For drinking …
