Polymer Dosing System

Polymer Dosing System Polyelectrolytes are used in wastewater treatment plants in flocculation and sludge dewatering operations.
Anionic polyelectrolytes are used in flocculation units, while cationic polyelectrolytes are used in filter press, decanter, and beltpress etc. sludge dewatering equipments.

It is advantageous to use an automatic polyelectrolyte preparation unit in continuous wastewater treatment plants in terms of saving from time and labour.

A polyelectrolyte preparation unit consists of a powder polyelectrolyte dosing system, a dilution tank, a liquid dosing system, and a stirring system.

Powder-form flocculants are placed into the dosing chamber and dosed to the eductor. The powder-form polyelectrolyte dosed from the eductor to the tank is mixed with the service water and thus the solution starts to form. The polyelectrolyte is dissolved in water by using a single chamber and a single stirrer or more than one chamber and more than one stirrer with different speeds.

The solution is stored in the solution storage chamber. Polyelectrolytes are dosed to the line that goes to the filter press, belt press, or sludge thickening tank via dosing pumps, and the system keeps running automatically with the help of the level sensor found in the storage chamber.

Entire automation of polymer dosing systems is controlled from the electric panel mounted on the unit.
