The raw water tank is made of SUS304 or PP material. Raw water pump provide the pressure to silica sand filter/active carbon filter. Silica Sand filter get rid of turbidity, suspended matter, organic matter, colloid and so on.
Active carbon filter Remove the color, free chloride, organic matter, harmful matter and so onion exchange
preventany deposition of large Particles, most of the bacteria, and viruses into the RO membrane,
The accuracy is 5um, for holding back any large particulates such as large iron, dust, suspended matter,
High pressure pump Provide the high pressure to RO membrane(at least 2.0 Mpa).RO system is the main part of pure
water treatment plant. The RO membrane's desalt rate can reach as high as 99%.
