RO + UV + UF Purifiers these are considered to be the best water purifier to purify water from all kind impurities like bacteria, germs, dissolved impurities and heavy metals. Some companies also use UF filters to make sure water is pure. These water purifiers can be used with any kind of water supply without worrying about the quality of output water.

Membrane Filtration using MF and UF excels other conventional filtration methods on both quality of effluent, requirement of energy and space, ease of operation and maintenance. In the membrane filtration, liquid is pressurized while passing tangentially through a semi-permeable membrane, the liquid selectively pass through the membrane, leaving desired particle sized suspended solids behind ultimately giving you the purest form of water.

Reverse osmosis is the key principle behind RO water purifiers. Water from higher TDS (total dissolved solids) level – that is, very hard water – is transferred to the lower TDS level through a filtering membrane. RO technology uses high pressure to push water through an extremely fine filter or membrane. The holes in this membrane are as small as .0001 microns. They remove dissolved salts along with pollutants and other physical contaminants including virus, and harmful metals, minerals, bacteria and microorganisms. Most of the RO purifiers also comprise of TDS controllers (to adjust the TDS level). The filter is kept clean by flushing the separated contaminants so they drain away.

In the quest to live healthier lives, many people have turned to water filters. Some water filters fit into pitchers to provide clean drinking water. Some filters attach to faucets and filter water as it flows out of the tap, and still others filter water as it enters a house so that all of the water in the home is filtered.

Kent Supreme

Kent Supreme Wall Mounted RO Water Purifier

The RO purification process is essential to remove dissolved impurities like arsenic, fluorides, heavy metals, etc. as they are harmful for health. Conventional RO purification technology, while purifying, rejects a very high percentage of water (around 80%) and only 20% purified water is recovered. Balance water is wasted and goes down the drain. KENT has developed an innovative and patented technology which offers 0% water wastage in RO purifiers. The heart of this technology is a computer controlled process wherein the membrane is washed automatically and more than 50% of water intake is recovered as purified water. The balance rejected water is stored in a separate ‘Reject Water Tank’, which can be utilized by consumers for household purposes. The net result is 0% water wastage.

What you need to know before buying a water purifier

Water being the most vital element of our life, its purity should be accorded the highest priority by each of us. Water is our Life Line. Many diseases in the third world are either water-borne or due to contaminated water. Unlike the western countries where tap water is safe for drinking, the water that comes through taps in the developing world...
