Fully Automatic Chemical Dosing and Water Treatment System – Made in China
We specialize in the design and manufacture of advanced water and wastewater treatment equipment. Our core business covers:
Petrochemical industry water treatment
Municipal water supply and purification
Urban and industrial sewage treatment
Domestic sewage treatment systems
Pure water and reverse osmosis (RO) equipment
Waste gas and pollution treatment solutions
Our fully automatic dosing system is pre-assembled and tested at our facility to ensure plug-and-play operation. Upon delivery, users simply:
Install the system in the dosing room.
Connect the metering pump outlet to the dosing pipeline.
Link the chemical tank inlet/outlet and water supply pipe.
Provide power and connect sensor signals (e.g., pH, conductivity) to the control cabinet.
This streamlined process reduces on-site installation time, minimizes errors, and ensures quick commissioning, guaranteeing project timelines and operational reliability.
Three-Tank Integrated Design – Enables continuous chemical preparation and dosing with minimal operator intervention.
Dual Feeding System – Supports both dry powder and liquid polymer for flexible chemical selection.
PLC-Based Automation – Fully automatic operation reduces labor costs and improves accuracy.
Precision Dosing Options – Equipped with a screw pump or metering pump (default: screw pump) for adjustable and consistent chemical delivery.
Compact & Easy Maintenance – Base-free design with a sleek structure for simple upkeep and long-term reliability.

The system uses a jet mixer to disperse chemicals or powders via high-speed water flow, enhancing dissolution efficiency and fineness. The three-tank overflow design 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 optimizes solution uniformity for consistent performance.
