|TDS||Total Dissolved Solids|
RO full form is Reverse Osmosis. In RO water purifier, it passes water through the pump to increase water pressure then pass that pressured water through RO membrane(semi permeable). During this process dissolved solids and TDS present in water are eliminated. RO water purifier converts hard water to soft water. The disadvantage of RO water purifier is it produce a lot of waste water.
UV water purifier uses UV radiations to kill contaminants, microorganisms. Treating water passes through the UV radiation source tube and exposes water to UV radiation. UV water purifier is advisable to use with soft water which has contaminants.
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.
TDS full form is Total dissolved solids. Minerals, salts or dissolved metals such as calcium, chloride, nitrate, iron , sulfur and some organic matter that dissolved in water commonly referred as TDS. TDS expressed in terms in milligrams (mg) per liter of water, also referred in parts per million (ppm). Preence of TDS in water will affect the water taste. If you are not sure of the water hardness you can test it with the small devise called TDS meter. TDS value of 500 mg/l water is considered as very hard. Most commonly used purification systems to reduce TDS are carbon filter and reverse osmosis(RO).
