recent achievements in polymer bio-based flocculants for low cost

the flocculants, designed for coal slime water treatment, were characterized using the ftir, xrd and sem methods. it has been shown that water turbidity was reduced by ~97% and ~94%, while cod removal was ~78 and ~74% in the presence of fe 3 o 4 -chitosan-cellulose and fe 3 o 4 -chitosan-biochar, respectively.

difference and application of cationic, anionic and nonionic pam,nonionic polyacrylamide use; sewage treatment agent: when the suspended sewage is acidic, it is more suitable to use nonionic polyacrylamide as flocculant. pam plays an important role in bridging adsorption, which makes suspended particles produce flocculation and sedimentation, and achieves the purpose of purifying sewage.

water soluble polymer flocculants synthesis

polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly(vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7
