Reverse Osmosis Water Systems

Reduce a broad spectrum of contaminants using 4-stages of treatment.

  • Stage 1- sediment prefiltration for mechanical reduction of rust and particulate, and provides membrane protection.
  • Stage 2- activated carbon prefiltration for reduction of tastes, odors, chlorine, and organic impurities.
  • Stage 3- high-flux reverse membrane for reduction of dissolved solids, including the rnage of toxic heavy metals, plus Giardia & Cryptospordium cysts.
  • Stage 4- activated carbon postfiltration for final polishing of off-tastes & odors.
