Water filter design

This system is a 5-stage RO system and these stages include:

  • Stage 1 filter: a 5-micron poly-proplene sediment filter – This pre-filter is a sediment filter which can remove dust, rust, sand and other large sediment.
  • Stage 2 and 3 filters: a 5-micron activated carbon and carbon block – At these 2 stages, chlorine, cloudiness, VOCs, as well as other organic chemicals can be effectively removed or reduced. The bad odor and taste of chorine can be eliminated.
