10,000 L/H Auto-Dosing System | Wastewater Treatment

2025 Best-Selling 10,000 L/H Automatic PAM/PAC Dosing System for Sewage Treatment

Product Overview
Automatic dosing systems are essential in modern wastewater treatment processes, enabling continuous and efficient preparation of polymer solutions such as PAM (Polyacrylamide) and PAC (Polyaluminum Chloride). These systems ensure consistent flocculation and coagulation, enhancing solid-liquid separation and treatment efficiency. The main components include: polymer feeding unit (with hopper), powder pre-wetting device, solution preparation tank, liquid level controller, agitator, dosing pipelines, and an integrated electrical control panel.

Working Principle
Dry polymer is accurately fed into the mixing tank, where it is dissolved and matured under controlled agitation. The prepared solution is then delivered to dosing points via precision metering pumps. The dosing rate is fully adjustable to meet varying process requirements across different treatment stages.

System Components

1. Polymer Dosing Unit

   • Includes a hopper with observation window and level sensor, a screw feeder driven by a high-precision reducer, and optional electric heaters in the discharge area to prevent powder bridging and ensure smooth material flow.

2. Polymer Dissolution Unit

   • Comprises a pre-wetting chamber and a three-compartment tank (pre-mixing, maturation, and storage) equipped with individual agitators. This design ensures complete polymer activation and homogeneous solution quality.

3. Water Supply Unit

   • Consists of water pipelines manual ball valves, water filters, pressure gauges, solenoid valves, shut-off valves, and rotameters to regulate and monitor water input accurately.

Key Features

• Fully automated operation reduces manual intervention

• High-capacity design suitable for large-flow applications (10,000 L/H)

• Compatible with both PAM and PAC preparations

• Durable construction with corrosion-resistant materials

• User-friendly interface with programmable logic control

Applications

• Municipal wastewater treatment plants

• Industrial effluent treatment facilities

• Sludge dewatering processes

• Drinking water purification systems
