RO, UV, UF and TDS meaning

There are many different types of water purifiers system, each uses a different type of technologies to purify water. The answer for what type of water purifier is best for your home to depend on the type of water in your area hard or soft water and contamination level.

Try our water purifier selector to choose right water purifier by answering simple questions without reading any buying guide.

RO Reverse Osmosis
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.

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.

TDS

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).

See the list of best RO+UV, RO, UV, gravity based water purifiers for further information.

Apart from the above information, we got frequent queries about the same information in different forms of questions, presented for your reference.

What is the meaning of reverse osmosis?

Reverse Osmosis is a water purification technology. The most common use of RO is to reduce the water hardness and eliminate contaminants like Fluoride, Arsenic, Lead.

What is the full form of RO?

Reverse Osmosis is the full form of RO.

What is the use of TDS in water purifier?

TDS full form is Total dissolved solids. There is no use of it, it is simple a measure of hardness. Water with the 500 mg/l TDS value is considered as very hard.

What is the meaning of RO in Hindi?

RO is acronym for Reverse Osmosis. 'R' from Reverse, 'O' from Osmosis. 'John' is a name in English, and it is same meaning in Hindi also John.

What is RO MF?

MF is full form of Micro filtration purification technology. In MF purification the water is passed through a special pore-sized membrane to separate microorganisms. Both reverse osmosis and nano filtration are fundamentally different since the flow goes against the concentration gradient.

In a recent research found that if MF filtration is used as pre-filtration, before RO purification, the purification results are much effective. Kent released such MF + RO purifiers in the market as well.
