Dosing System

Dosing systems are precision chemical injection units designed to deliver controlled quantities of chemicals into industrial processes. They are commonly used in water treatment, mineral processing, and process control applications.
Engineering Overview
Metzix Automated Chemical and Polymer Dosing Systems provide precision metering, dilution, and aging of coagulants, flocculants, and flotation reagents. Engineered to eliminate chemical waste and maintain stable process chemistry, each skid includes dry-powder or liquid reagent feed, high-shear multi-stage wetting chambers, gentle aging tanks with turbine agitators, and precision progressive cavity or diaphragm metering pumps. Controlled by integrated PLCs, Metzix dosing skids optimize reagent use while ensuring consistent thickening and separation.
Key Features & Engineering Advantages
Performance & Economic Benefits
