Rofilters.com RO Systems - Reverse Osmosis Water Filters - is a Home Drinking Water System that uses the principle of reverse osmosis to remove 95-99% of all the mineral and chemical contaminants from tap water. Rofilters.com products gives you the quality of fresh, pure, drinkable water with the convenience of a faucet mounted on your kitchen sink.
Reverse osmosis is a separation process that uses pressure to force water through a membrane. The process requires high pressure which is been exerted on one side. On the surface of the membrane retains the dirt, chlorine, microbes and any other obnoxious substance so that pure water passes to the other side. Because the membrane is semi permeable, through it is allowed to pass only pure water. The pressure is usually 2-17 bar for fresh or brackish water and 40-70 bar for seawater.
How does Reverse Osmosis differ from a Water Filter
Ordinary water filters use a screen to separate only particle of dirt sediment from water. Because they don't include a semi permeable membrane, allow several contaminants to pass through the filter. In addition the remain dangerous substances, are trapped in the filter which means that the new water which passes through it, gets in contact with them. As we know bacteria need humidity and heat in order to multiply.
Reverse osmosis because of its semipermeable mebrane not only removes an extremely high percentage of dissolved contaminants from tap water but also rejects the remain on its surface substances to the drainage.
