The organic coagulants are polymers with high cationic charge, which is essential for destabilizing the negatively charged colloidal particles and providing rapid flocculation. Organic coagulants have several advantages compared with inorganic: they provide effective results with a significant dose reduction (up to 10 volumes/hour), not altering the pH of the treated water; minimizing the amount of formed sediment, etc.

 

Organic flocculants are water-soluble macromolecular compounds which are absorbed or chemically bound with the surface of the dispersed phase when added into dispersion systems and unite the combined particle into agglomerates (floccules), encouraging their rapid sedimentation.

 

Organic coagulants and flocculants are widely used in drinking water treatment, wastewater and sludge dewatering.
