Definition
Polyelectrolyte (flocculant) is an organic chemical. It is widely used for flocculation in water treatment. It is used in drinking and utility water treatment, wastewater treatment, and sludge dewatering.
Application Area
Cationic polyelectrolyte is widely used in the sludge dewatering units of wastewater treatment plants.
In processes where sludge dewatering is performed with a decanter centrifuge, belt press, or filter press, cationic polyelectrolyte, mixed with the aid of a static mixer, is dosed into the pressurized sludge line.
The working principle of the cationic polyelectrolyte product is generally based on ion exchange between the polymer chain in the aqueous solution and the electrical charges of suspended solid particles.
The stable structures of the solid particles are disrupted, leading to coagulation or flocculation.
Cationic polyelectrolytes are diluted to between 0.05% and 0.5%.
The preparation solution is generally prepared at 0.1%–0.2% by adding the powdered product to water during mixing.
Since the characteristics of the sludge to be dewatered vary, the dosages to be applied are determined in a laboratory environment through jar tests and plant trials.
