Coagulants and Flocculants

WSET coagulants and flocculants are formulated to assist in the solids/liquid separation of suspended particles in solution.  Such particles are characteristically very small and the suspended stability of such particles (colloidal complex) is due to both their small size and to the electrical charge between particles.  Conditioning a solution to promote the removal of suspended particles requires chemical coagulation and/or flocculation.

Coagulants neutralize the repulsive electrical charges (typically negative) surrounding particles allowing them to "stick together" creating clumps or flocs.  Flocculants facilitate the agglomeration or aggregation of the coagulated particles to form larger floccules and thereby hasten gravitational settling.  Some coagulants serve a dual purpose of both coagulation and flocculation in that they create large flocs that readily settle.

COAGULANTS: to create larger particles by neutralizing electrical charges surrounding small particles in solution.

C-05: A liquid inorganic coagulant with cationic charge and an organic polymer added to perform as a coagulant, an emulsion breaker and phosphate precipitant.
C-3: A liquid inorganic polymer that forms dense, sheer-resistant particles/flocs to promote settling and reducing the need for subsequent flocculation.
C-5: A liquid blend of inorganic and organic polymers to replace alum, ferric chloride, ferrous sulfate and other inorganic salts.
C-117: A liquid blend of alum with an organic polymer.LA-50:  A liquid inorganic coagulant blended with organic polymer to accelerate the settling of suspended particles.
M-25: A concentrated liquid, organic, highly cationic, high molecular weight polyquaternaryamine.
P-25: A concentrated liquid, organic, water-soluble, low cationic quaternary ammonium polyelectrolyte.

FLOCCULANTS: to facilitate the settling of suspended solids in solution.
