1-2.3 Quartz sand filter
Function: get rid of turbidity, suspended matter, organic matter, colloid, ect.
1-2.4 active carbon filter
RO system requires the inputting water (Silting Density Index) SDI≤5, residual chlorine <0.1mg/L.
Function: Remove the color, free chloride, organic matter, harmful matter, ect. The adsorption rate was about 60%. Dislodge peculiar smell, pigment, improve water clarity.
1-2.5 Soft filter(Resin filter)
The filter filled with Na ion exchange resin.
1-2.6 Micron filter
Function: Prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um.
1-2.7 High pressure pump
Function: Provide filtration working pressure for reverse osmosis system which makes the inputting water pressure get 10kg, so as to meet inputting water pressure and outputting water amount.
