What is reverse osmosis?
Reverse osmosis is the most convenient and effective method of water filtration. Often referred to as RO, is an advanced water purification method. It was initially developed by the U.S. Navy to produce drinking water from sea water for submarine crews.
It is a membrane filtration technology that works by forcing water under pressure through the very tiny pores of a semi-permeable membrane. Modern reverse osmosis units for the home combine membrane technology with carbon and mechanical filtration to produce highly purified, great-tasting water.
Simplified Version:
Water is driven by city water pressure.
1) It flows first through a through a sediment filter where silt, sediment and particles (like sand and clay) are removed. It protects the automatic shut-off and the membrane from clogging with debris.
Then water flows through two types of Carbon Pre-Filters, which removes organic contaminants including chlorine and its by-products.
2) Catalytic Carbon Pre Filter is specific to Chloramines. This is how Bay Area disinfects water.
3) Granular Activated Carbon Pre Filter for Chlorine and other chemical contaminates such as pesticides. Some Units will have a Fluoride Filter instead.
4) Next, it enters the reverse osmosis membrane, a very tight, sheet-like filter, that allows water to pass but rejects dissolved solids like sodium and impurities like lead and arsenic. Some of the water entering the unit is used to cleanse the membrane surface and flows to the the kitchen drain pipes.
The purified water is stored in a small storage tank until it is needed.
5) When the RO faucet is opened, the purified water is forced by air pressure through another carbon filter, which gives it a final polish and from there to the RO faucet.
6) Final Stage, water flows around the ceramic beads were trace amounts of minerals are returned to the water. This creates naturally alkaline water with slightly negative charge.
Note: The simplified description omits a few very essential parts like flow control devices, check valves, and an automatic shutoff devices that stops the inflow of water when the storage tank is full.
FAQ
What are 3 types of RO?
- Desalination System: used to desalinate sea water for consumption, irrigation etc.
- Brackish Water System: used to clean high salinity water (dirtier than tap water).
- Water Treatment Plants: used to clean a large area of surface, brackish and seawater.
What is the principle of RO Plant?
Which process is used in RO?
Reverse Osmosis, commonly referred to as RO, is a process where you demineralize or deionize water by pushing it under pressure through a semi-permeable Reverse Osmosis Membrane.
