Raw water source: Bore whole, river, well, mountain spring, lake, etc
Raw water pump/multi pump: Nanfang, Grundfos
Filter media: Quartz sand filter, active carbon filter, security filter( PP filter)
RO Membrane: Filmtec Dow,Hydranautics
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, 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. Micron filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um,
6. High pressure pump-- Provide the high pressure to RO membrane ro.
7. RO system-- main part of the plant. The RO membrane's desalting rate can reach 99%, removing over 99% ions
