About the system
The RO-4 at a glance
Galene's RO-4 Whole Home Reverse Osmosis series is based on reverse osmosis technology, the highest level of filtration grade in the market, delivering the most effective contaminant removal. It comes complete in a four-stage configuration: pre-treatment that conditions the water to prevent premature failure of the membrane; an RO skid with micron filtration, booster pump, RO membranes and instrumentation; a finished-water holding tank with repressuring booster pump and pressure tank; an ozone disinfection system; and a post carbon and calcite filter for pH correction and improved taste.
- Reverse osmosis at every tap: the highest level of filtration grade in the market.
- Reduces sediments and rust, chlorine odor and taste, lead and other heavy metals, fluoride, pesticides, bacteria, parasitic protozoan cysts, VOCs and MTBE.
- Reduces PFAS, disinfection by-products and halomethanes.
- Treats a large variety of heavy metals, including aluminum, arsenic, barium, cadmium, copper, cyanide, mercury, nitrate and more.
- Ozone disinfection of the stored water, and calcite for pH correction and improved taste.
