Applications
This automated dosing system is designed for the preparation and injection of water treatment chemicals in various applications, including:
Supply water, boiler water, circulating water, and wastewater treatment in power plants
Petroleum, chemical, environmental protection, and water supply industries
Ventilation and condenser systems to prevent scaling caused by calcium carbonate, magnesium carbonate, and biological sludge, thereby maintaining operational efficiency.
System Structure
The system is a skid-mounted unit integrating major components including:
Solution tanks
Mixers
Metering pumps (or screw pumps)
Y-type filters
Safety valves, back-pressure valves, check valves
Pulse dampeners
Level gauges and pressure gauges
Control cabinet and installation platform
Designed for plug-and-play operation, the unit only requires connection to feeding pipes and power supply. It automatically monitors fluid pH and adjusts chemical dosing accordingly. This integrated approach significantly reduces engineering and installation efforts, enabling largely unattended operation and ensuring system reliability and safety.
Key Features
Three-Tank Continuous Preparation: Ensides consistent operation with easy access for operation and maintenance.
Dual Feeding Capability: Supports both dry powder and liquid polymer feeding for flexibility based on process requirements.
Full Automation: PLC-controlled operation reduces manual intervention and enhances reliability.
Precise Dosing Options: Equipped with either a screw pump or metering pump (standard) for accurate and adjustable chemical injection.
Compact and Integrated Design: Base-free structure with a streamlined layout offers a compact footprint, aesthetic appearance, and ease of maintenance.
Packing and Delivery
1. Waterproof packing with the international export standard by 20ft, 40ft, 40hp container. Equipment Fittings, Electric Motor and Power Cabinet will be packed in Wooden Case or Iron Box. Other Equipment will be packed by Color-Stripes Plastic Cloth.
