Product introduction of PAM PAC Dosing System
The PAM PAC dosing system for wastewater treatment is an advanced automatic polymer preparation and chemical dosing equipment widely used in industrial and municipal water treatment plants.
It consists of a polymer feeding device, dry powder infiltration unit, dissolving tanks, mixer system, water supply pipeline, and electric control panel.
The system automatically handles dosing, dissolving, and feeding processes to produce a stable polymer solution. It supports adjustable concentration control and ensures consistent chemical reaction performance in wastewater treatment applications.
The hopper system includes a screw feeder driven by a high precision reducer, ensuring stable dry powder dosing. A heating device prevents powder caking, ensuring smooth operation.


Working principle
The PAM PAC dosing system operates through a fully automated polymer preparation process.
Working steps:
- Dry polymer powder is fed from hopper via screw feeder
- Powder is pre-soaked and infiltrated in pre-mixing device
- Material enters multi-stage tanks for mixing and activation
- Mixer ensures uniform dissolution and stable concentration
- Prepared solution is stored in solution tank
- Water supply system controls flow and dilution ratio
- Final solution is delivered to dosing point automatically
This ensures continuous production of high quality polymer solution for wastewater treatment applications.
