What consist a perfect pure water treatment system

For a perfect water treatment system,it includes pump,silica sand filter, active carbon filter, sodium ion exchanger, precision filter, reverse osmosis, UV, ozone mixing tower, ozone generator and water tank. Every device in this system has its own function.As long as one of those devices goes wrong, your pure water will be unqualified.
 
1. Raw water pump-- provide the pressure to silica sand filter/active carbon filter 
2. Silica Sand filter-- get rid of turbidity, suspended matter, organic matter, colloid and so on 
3. Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter and so on 
4. Precision filter--prevent any 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, impurity. 
5. High pressure pump-- Provide the high pressure to RO membrane(at least 2.0 Mpa). 
6. RO system--RO system is the main part of pure water treatment plant. The RO membrane's desalt rate can reach as high as 99%, it is capable of removing over 99% of ions, bacteria, particles and 98% of organic.
