Polymer Dosing System
Polymers preparation and dosing system, is an automatic continuous process, dedicated for the preparation of chemicals used in the water and wastewater treatment. It dissolve dry chemical/polymer powder or can be customized to dilute concentrated solutions.
Feature:
1, Dosing, dissolving and feeding function are integrated, full automatic operation. Well designed dosing and heating device can reduce polymer caking;
2, Polymer and water inletting are adjustable, All concentration of the liquid can be reached according to your needs. The machine will remind to add polymer when the polymer reaches low level;
3, Optional: Vacuum feeding machine, Online dilution system; Tank material: SS304 or SS316L, Polypropylene, FRP, etc.
