RO+UV/UF Water Purifier
RO+UV/UF types of water purifier used in water plant are the combinations of RO i.e. Reverse Osmosis and UV/UF i.e. Ultra voilet / Ultra filtration.
RO(Reverse Osmosis) water purifier uses a semipermeable membrane to purify the water from impurities. To pass water through the RO water plant membrane, the purifier uses a water pump that pressurizes raw water to pass through the RO membrane with a good amount of pressure. RO water purifier is the most effective purifier to purify hard, saltwater containing dissolved solids and chemicals. Only RO water purifier is capable of removing metal particles like lead, arsenic, chlorine, fluoride, nitrates, and sulfates. If you have this type of water purifier at home, rest assured and get purified, safe drinking water. It passes water through the pump in the RO water plant to increase water pressure and then pass through the RO membrane (semi-permeable). The dissolved solids and TDS present in water are removed during this process. RO water purifier Coverts hard water into soft water. The RO water purifier’s disadvantage is that it produces a lot of waste water.
UV(Ultraviolet) water purifier is a proven technology that capable of killing waterborne disease-causing microorganisms, pathogens such as bacteria, viruses, and cysts. This environmental-friendly technology doesn’t use any chemicals during the purification process. UV water purifier consists of a UV lamp tube through which the water has to pass during purification. UV lamp releases UV lights and the running water gets exposed to UV light, where germs like bacteria and viruses are damaged and made inactive. However the germs dead bodies remain in the water, but these are not harmful for human health anymore.The UV water purifier is ideal for low TDS (Total Dissolved Solids) water like lakes, river water. UV water purifiers are incapable of treating hard water, which generally has a higher TDS level. Just as a UF water purifier, UV water purifier does not remove chemicals present in the water.
UF or Ultrafiltration uses hollow fibers of a membrane made up of a thin layer of material which is able to separate water and other particles present in the water. When water is fed through the UF membrane, bacteria, and viruses, suspended solids, are retained in the UF membrane. Basically, UF is very much alike to RO technology, the only the difference is RO can block very minute particles, whereas UF can not. UF water purifier is ideal for the places where the presence of chemical contamination is low because UF can not remove chemical particles present in the water. The important thing to remember is that UltraFilteration can not filter hard water.UF full form is Ultra filtration. UF water purifier contain hollow fiber threaded membrane. UF removes dispersed material, suspended solids, and other large molecular weight materials from water which are harmful to human health. UF water purifiers are works without electricity.
