Reverse Osmosis (RO) systems purify water by forcing pressurized water through a very fine, plastic membrane.
Wells and Private Water Sources:
If the raw water being treated comes from a well, or another private source, disinfection and pre-filters to remove chlorine, particulates and sediment may be needed in advance of the RO unit to remove contaminants that can foul, or damage the membrane.
Stages of Reverse Osmosis:
- During the initial filtration stage, tap water or well water, is passed through a particle filter that removes silt, sediment, sand and clay particles that might clog the RO membrane.
- The water is then forced through an activated carbon filter that traps minerals and contaminants such as chromium, mercury, copper, chloramine and pesticides. It also removes chlorine, which is important as chlorine will shorten the life of the membrane.
- Water is transferred under pressure into the RO module, allowing only clean water to pass through the small pores in the membrane. Impurities unable to pass through the membrane are left behind and flushed down the drain.
- Treated water is then sent to a storage tank.
- Treated water is passed through an activated carbon filter before use, to further improve the water’s taste and smell!
