Product Description

Water RO System Purification Plant Machinery Automatic Cleaning 

Product Description

Working process
1. Raw water pump— provide the pressure to quartz sand filter/active carbon filter.
2. Multi-medium filter–get rid of turbidity, suspended matter, organic matter, colloid, etc.
3. Active Carbon filter–Remove the color, free chloride, organic matter, harmful matter, etc..
4. High pressure pump–Provide the high pressure to RO membrane ro.
5.RO system— main part of the plant. The RO membrane’s desalting rate can reach 98%, removing over 98% ions.
