    Flocculants an overview ScienceDirect Topics

    Most commercial flocculants are synthetic water soluble polymers with average molecular weights in the region 1000 to 30 × 10 6.They are generally supplied as powders that have a limited storage life, particularly when made up into solution. While there is an understandable reluctance for manufacturers to divulge their exact chemical nature, it is known that the majority of polymer

    Amphoteric flocculants usually are prepared by amination of lignosulfonates. For example, the amphoteric flocculant can be prepared with lignosulfonate (or its silicone-modified product) and polyacrylamide [26].This flocculant can increase the retention of small fibers and fillers for papermaking, which improves the physical properties of paper.

    Martien Cohen Stuart, Hans Lyklema, in Fundamentals of Interface and Colloid Science, 2005. 2.7a Flocculation. Many commercial flocculants are often cationic polyelectrolytes. In particular, high molar mass copolymers with a relatively low fraction of charged monomer units and the remaining units water–soluble but uncharged are very effective flocculants.

    Flocculant didn’t work well alone when the concentration of leachate was low. Besides, COD removal efficiency was only 22% by ferric chloride of 1200 mg/L. So, flocculant aid was needed to improve ferric chloride flocculant coagulation performance. Polymer flocculant aid can be used to increase skeleton and weight of alum flowers and improve

    Flocculation is used primarily for the precipitation of inorganic substances. It is used to enhance sedimentation or centrifugation. The waste stream is mixed while a flocculating chemical is added. Flocculants adhere readily to suspended solids and to each other (agglomeration), and the resultant particles are too large to remain in suspension.

    For example, Kim et al. [90] investigated the flocculation of yeast suspensions prior to MF using commercially available synthetic polymeric flocculants. Cationic polymers were shown successful in flocculating the yeast suspensions. Flocculation prior to MF lead to an increase in the permeate flux, and an optimum polymer concentration, which maximized the degree of flocculation, was found.

The stirring is subsequently slowed
