What is reverse osmosis?

However, reverse osmosis process sounds like a complicated process, but actually, it not that difficult to understand. Reverse osmosis is a water purification process in which a semi-permeable membrane is used to remove the molecules, ions, and larger particle from the drinking water.

How RO water purifier works?


An RO water purifier usually consists of sediment filter, pre-filter, RO membrane, and post carbon filter. Before passing through the RO membrane water is made to pass through the sediment filter and carbon filter to remove the dust particles and chlorine from the water. As these impurities can harm the RO membrane and shorten the life of the RO membrane. Therefore to protect the RO membrane, sediment filter and pre-carbon filter are used. Water is then passed through the RO membrane under pressure, water atoms being smaller in size are permitted to go through the ultra-fine pores of the membrane, while the rest of the contaminants are obstructed behind. The purified water is stored in the storage tank and the impure water is rejected by the purifier.

During RO process only pure water can pass through the membrane. Moreover, there are also some essential minerals present in water that cannot pass through the membrane due to their bigger size. But these minerals play a vital role in the proper functioning of the body. Therefore these minerals should not be removed from the drinking water. To retain the essential minerals in water Kent RO system has inbuilt TDS controller in the water purifiers that maintains the natural essential minerals.
