Why is Reverse Osmosis Filter Popular?
Reverse osmosis systems is the most effective and most economical system for removing contaminants from the tap water. Once it is installed, your operating cost can be less than purchasing bottle water, and it will provide all the clean water for cooking, drinking and washing salad.
How Does Reverse Osmosis Work?
Reverse Osmosis water filtration is a process where water is forced through a semi-permeable membrane, leaving unwanted pollutants and contaminants behind. A Reverse Osmosis unit will provide you with clear, clean, fresh drinking water. The process uses no chemicals or electricity. It's the most effective technology known for the improvement of drinking water. Since the membrane pore is close to water molecular structure, you will get almost pure water.
Stages of reverse osmosis:
- During the initial filtration stage, tap water or well water (pressurized by a booster pump) is passed through a particle filter (a pre-filter) that removes silt, sediment, sand, and clay particles that might clog the R/O 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 R/O 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.
