FLOCCULANTS by definition means a process in which individual particles of a suspension form aggregates. In the water treatment industry, the terms coagulation and flocculation imply different mechanisms. Flocculants consist of various molecular weight anionic, nonionic and cationic polymers. They are used to increase the efficiency of settling, clarification, filtration and centrifugation operations.
FLOCCULATION is used to describe the action of polymeric materials which form bridges between individual particles. Bridging occurs when segments of a polymer chain adsorb on different particles and help particles aggregate. The benefit of a flocculant is that it can carry active groups with a charge which will counterbalance the charge of the particles, and adsorb on particles and cause destabilization either by bridging or charge neutralization.
An anionic flocculant will usually react against a positively charged suspension (positive zeta potential). That is the case of salts and metallic hydroxides.
A cationic flocculant will react against a negatively charged suspension (negative zeta potential) like silica or organic substances.
TRAMFLOC'S cationic coagulants remove the total suspended solids (TSS) and accompanying turbidity so that the raw water will be of suitable quality for process use or for potable treatment. The Tramfloc products in the 620, 630, 720, and 730 series products are designed to neutralize the surface charges on colloidal solids, thus promoting rapid and effective coagulation. This series of formulations can dramatically reduce metal salt feed rates.
Tramfloc flocculation applied in industrial, municipal, and mining industry dewatering systems will improve water release which will produce drier cake. When we increase cake solids, we axiomatically reduce sludge volume and you save on disposal costs. Tramfloc formulations cover the entire spectrum of molecular weights and ionic charges. Our products can help dewater inorganic, biological, and radioactive sludge.
