WATER PURIFICATION SYSTEM RO-UV-UF

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.
Ultraviolet Purifier:
UV purification or disinfection is the best option (for water with a low TDS) to get rid of microorganisms like bacteria, viruses and cysts without removing essential minerals that are in your drinking water. UV purification is the most eco-friendly way to purify water because it does not add any chemicals to your water and it does not waste any water. For ‘soft’ water which is treated by the authorities and may have been contaminated during distribution, UV treatment is very effective in purifying water at the point of use.
