Water Purification System RO-UV-UF
Drinking clean water is imperative to good health. Given the widespread pollution of water bodies, and ageing distribution pipelines in most cities, tap water is no longer a reliable source of water.
The main purification technologies available today revolve around UV (Ultra Violet light), and RO (Reverse Osmosis membrane). A lot of people are under the impression that reverse osmosis (RO)-based water purifiers are, in general, a better choice of water purifiers as compared to UV(ultraviolet) based ones. This is a serious misconception. Now, before we delve deeper into which water purifier is right for you, let us first understand the basics of water purification technology.
Reverse Osmosis Purifier
RO purifiers filter out or separate 90% of dissolved pollutants through its semi permeable membrane. Reverse osmosis membranes remove upto 90% of whatever is dissolved in your water including essential minerals if any. So, if the TDS (Total Dissolved Solids) levels are say 900 ppm, (parts per million – a measure of TDS) , post RO it will be in the range of 90 ppm. If the TDS is say 300, then post RO the TDS will drop to 30, which is lower than ideal. So, it is safe to say TDS levels of over 500 ppm, warrant a RO system. Using a RO purifier for water with a low TDS to begin with often strips away minerals like calcium and magnesium, leaving water with extremely low TDS levels, which may not be best either from the taste or health point of view.
It is also good to remember that RO purifiers are not very efficient and waste up to 80% of the water being treated, which simply goes down the drain. This puts a strain on our already scarce water resources.
