There are several kinds of purifiers in the market. Most popular types are RO (reverse osmosis), and UV (ultraviolet) based. Besides these, there are simple candle filter purifiers, softener plants, and distill water plants (used for commercial purposes alone).
UV based water purifier systems used to be sold more than RO purifier systems till recently, but things have begun to change. According to Frost and Sullivan, roughly 41 percent of all purifiers sold in India are now RO based. This is quite high considering the world average of only 11 percent.
Not all purifiers should be sold everywhere, but the bias towards RO purifiers seem so imminent. RO purifiers should be used at only those places where total dissolved solid (TSD) count in water is more than 100 ppm (parts per million). Below this, UV purifiers are recommended, but RO purifiers seem to be a clear favorite among people.
RO purifiers are preferable for ground water usage, or where water is hard or salty. “In water supplied by Delhi Jal Board, TDS count is between 90-150 ppm. RO is still advised in Delhi because corporation water often contains excess fluoride, calcium, magnesium, and even nitrate, ammonia and pesticides.”
RO leaves only 10 percent ppm of TDS after purification. However, TDS count below 50 ppm is good for human health. RO may, therefore, actually deprive water of beneficial minerals also. Perhaps this explains why Kent has come up with a new solution. It has attached a TDS mixture with membrane, a vital component in purification of water in RO purifiers. TDS mixture allows some water to go straight to storage tank and mix with the purified water. This helps in maintaining the optimum TDS count, saving water from being deprived of necessary minerals.
