Low-Consumption Automatic Polymer Dosing System for Wastewater Treatment
Our intelligent chemical dosing system uses sensor signals to automatically control the operation of dosing pumps. By monitoring parameters such as pH and conductivity, the system ensures precise chemical dosing to maintain optimal wastewater treatment conditions.
During operation, the target parameter (e.g., pH or conductivity) is set based on system requirements. If the pH deviates from the set point—indicating increased acidity (risk of corrosion) or alkalinity (risk of scaling)—the sensors trigger the control system to activate the dosing pump. Chemicals are injected until values return to the desired range, after which the pump automatically shuts off. This ensures efficient, automated, and responsive treatment.
Three-Tank Integrated Design – Enables continuous preparation, offering ease of operation and maintenance.
Dual Feeding Options – Supports both dry powder and liquid polymer, accommodating varied treatment needs.
Fully Automated PLC Control – Reduces manual intervention and improves operational efficiency.
Precise Dosing Mechanism – Utilizes a screw pump or metering pump (default: screw pump) for accurate and adjustable chemical delivery.
Compact and Base-Free Structure – Sleek, easy-to-maintain design with a small footprint.

The system employs a jet mixer that uses high-speed water flow to disperse chemicals or powder, enhancing fineness and accelerating dissolution.
The three-tank overflow configuration ensures continuous preparation, maturation, and dosing. By leveraging gravity and solubility differences, the system automatically separates dissolved and undissolved substances. A low-speed agitator further enhances solution homogeneity, ensuring consistent and efficient chemical feeding.
Optimized for: Wastewater Treatment Plants, Industrial Water Recycling, Effluent Management.
Key Benefits: Energy-Saving, Automated Operation, Accurate Dosing, Low Maintenance.
