Difference between RO, UV, UF water purifiers

RO : Reverse

 UV    : Ultraviolet

                                                UF    : Ultra Filtration

                                  TDS  : Total dissolved solids

RO

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

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.. UV light does not work to eliminate contaminants such as chlorine, heavy metals and VOC’s (Volatile Organic Compounds).

UF

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
