1) Need enough flushing after installation and changing filters.

2) It takes 1week to get the correct value of TDS (after stabilizing RO membrane)

3) Rate of removal and the volume of treated water depends on water temperature, water pressure,

    condition of raw water and etc.

4) Product Specifications for RO Membrane.


MODEL Water Pressure(kgf/cm) Water temperature(°c) Capacity of treated water(ml/min) GPD Removal(%)
