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.
