Polymer Water Treatment: How Coagulants & Flocculants Clean Water

In industry, we would consider sludge passing the paint filter test to be dewatered. Polymer flocculants expedite the dewatering processing by allowing water to leave the flocculated solids more freely. This video shows the coagulation, flocculation, and sedimentation process in real-time. This opens in a new window.

Flocculants can be cationic and anionic as well. The most common use of cationic polymers in water treatment is for the coagulation and flocculation of sewage treatment sludge in the dewatering step. No separate coagulant is needed in many cases which actually means the polymer is both a coagulant and a flocculant.

coagulants and flocculants for liquid solids separation

Coagulants and Flocculants for Liquid Solids Separation

Flocculants are commonly used with coagulants and are a substance that helps the clumping of fine particles into a "floc", especially in the treatment of wastewater. Flocculation is the process in which colloids — low-diameter particles that affect water's color or turbidity — are suspended in the form of loosely clumped particles called flocs.

INTERN VIEW: Coagulation vs. Flocculation

A flocculant is a long polymer that has positive charges along the polymer chain. Very simply, think of this as a long polymer made of starch, and it has charges along it. Starch is usually neutral, so what we do in manufacturing is we react it with chemicals that give it a positive charge.
