What is RO UV and UF Water Purifier?

Published on : July 4, 2019

Clean drinking water methods like RO, UV, and UF in water purifiers are a must in today’s day and age. ‘Dirty water’ harms beyond just water-borne diseases. The real slow killers are contaminants like arsenic, lead, and other poisonous particles that may prove fatal in the long run. For such times, it is best to invest in a trusted water purifier that will remove every harmful particle and solvent and ensure you stay healthy.

There has been a longstanding debate about RO vs. UV vs. UF water purification systems. You can choose either of those or a combination like RO UV Water Purifier. There is a difference between RO UV and UF technology and how they contribute to making water safe for consumption. To be able to make a decision, let us give you a brief about them all.

Here is the difference between RO UV and UF water purifiers for your clarity:

What is RO UV UF?

What is RO Water Purifier?

Term ‘Reverse Osmosis’, an RO water purifier, is considered the best in the market. This water purifier applies a force along the area of concentrated water. This water flows through a semi-permeable membrane, resulting in Pure RO Water. The process doesn’t simply eliminate harmful particles but also gets rid of dissolved solids. This procedure converts hard water into soft water, making it fit for consumption. It comes enabled with a pre-filter, a sediment filter, a carbon filter, and a Side Stream RO membrane. Thus, natural minerals and nutrients are retained for a healthy lifestyle while eliminating only harmful elements. With Advance Recovery Technology, maximum water is retained, resulting in minimal wastage.

RO water purifier is an appropriate method to reduce TDS in water.

What is UV Water Purifier?

The most basic form of water filtration can be done using a UV water purifier, which utilizes UV radiation to kill germs. The water is forced through a tube and exposed to radiation. On the positive side, UV technology is chemical-free and easy to maintain. Unfortunately, it cannot eliminate TDS or eradicate the bacteria that the radiations manage to kill. The dead organisms continue to be present in the water you eventually consume.

What is UF Water Purifier?

The difference between UV and UF is that UF technology works without any electricity. It eradicates suspended solids, larger particles, and molecules from water through a hollow membrane. UF water purifiers can kill and eliminate bacteria and microorganisms but cannot get rid of dissolved solids. Unlike the RO water purifier, it cannot convert hard water to soft water. It is wise to use an RO UV Water Purifier, coupled with UF water filtration, for the best drinking experience, especially when you are not certain of the TDS Levels in the water.

RO UV UF Water Purifiers for Hard Water & TDS

To answer the question, what is TDS? And whether RO UV UF water purifier has a TDS controller to soften hard water?

TDS is an amalgamation of toxic substances in water generated by industries and pesticides. Reducing this is essential, making it wise to invest in an RO UV Water Purifier for clean drinking water.
