raw water→ 1 booster pump→ 2 sand(multi-medium) filter→3 active carbon filter→4 softener (optional)→ 5 security(micron) filter→6 high pressure pump→7 reverse osmosis system→ 8 UV sterilizer (ozone generator) →pure water storage tank
Function of each part of water treatment plant
1.booster pump-- provide the pressure to quartz sand filter/active carbon filter
2.Multi-medium filter-- get rid of turbidity, suspended matter, organic matter, colloid, ect.
3.Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter, ect.
4.Softener--exchange "ions" of calcium and magnesium with the most common and easiest method.
5.Security filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um
6.High pressure pump-- Provide the high pressure to RO membrane
7.RO system-- main part of the plant. The RO membrane's desalting rate can reach 99%, removing over 99% ions
8.UV sterilizer or ozone generator--- kill bacteria
