Advanced Automatic Polymer Dosing Technology
The automatic polymer dosing system adopts intelligent chemical preparation and precision dosing technology to ensure consistent polymer solution quality and stable chemical injection performance.
The system automatically completes:
• Dry polymer feeding
• Powder wetting and dissolution
• Solution mixing
• Aging and maturation
• Concentration control
• Continuous dosing operation
• Flow linked injection control
• Automatic chemical preparation cycles
Compared with manual polymer preparation methods, the automatic dosing system significantly reduces labor intensity, chemical waste, and dosage fluctuation while improving treatment consistency and operating efficiency.
Working Principle
Dry polymer powder is transferred into the preparation chamber through an automatic feeding device.
The system mixes polymer powder with controlled water flow to produce homogeneous polymer solution with accurate concentration levels.
Prepared solution passes through mixing and aging chambers to achieve full dissolution and reaction maturation.
The mature polymer solution is stored temporarily before entering the precision dosing section.
Metering pumps inject polymer solution into the wastewater treatment process according to preset flow rate, concentration, or treatment demand.
The automatic control system continuously supervises solution preparation, dosing quantity, alarm functions, water supply, and equipment operating conditions.
