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.
