Water Soluble Polymer Flocculants: Synthesis

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer acrylamide

Optimise your thickener efficiency for maximum profitability

Flocculants are used in most thickeners to obtain concentrations of overflow solids that will allow water to be reused or to comply with government regulations if the overflow is to be discharged. Recycled water containing 200 mg/L to 1% solids is generally acceptable. Most thickeners can achieve this level of concentration by using a flocculant.

Optimise your thickener efficiency for maximum profitability

Flocculants are mixed with the solid — liquid suspension in the entry feedwell of the thickener. The flocculants aggregate the fine particles which speeds up settling of the solids.
