The quality of drinking water is deteriorating day by day. It is no longer as pure as it was during our forefather’s time. Primary reasons why tapwater may no longer be safe for human consumption are:-
changes, draughts, rampant and uncontrolled industrialization has led to alarming levels of wastebeing disposed into our water sources such as rivers, water reservoirs and ground well water.
Aging pipeline network and poor maintenance results in municipal water getting contaminated by the time it reaches our homes.
Due to ever increasing pollution levels, the water sources are under dire stress and are getting contaminated with dissolved impurities, bacteria, viruses and cyst.Since the demand for municipal water is greater than the supply and due to the onset of multi-storied buildings, the practice of storing water in overhead tanks has become more common. These storage tanks are not airtight and become breeding grounds for unwarranted harmful micro-organisms like bacteria and viruses.With increased reliance on pesticides and insecticides in our agricultural industry, these harmful chemicals, when used excessively, percolate into the ground well water as well as get washed away into the rivers.Rivers are no longer sufficient to meet society’s ever increasing demand of drinking water and hence there is an increased reliance on ground well water, which contains excessive levels of dissolved impurities making the water hard (khaara).
The impurities present in drinking water can be classified into:-
Impurities:- These are the physical impurities which remain suspended in water such as dust, sand, dead insects and harmful micro-organisms like bacteria, viruses and cyst. They lead to discoloration of water and may also cause diseases.
Dissolved Impurities:- These are the chemical impurities which get dissolved and mixed with water. They cannot be removed by simple filtration techniques and require advance technology for removal. These impuritiesinclude chemicals, rust, pesticides, insecticides and salts of metals like arsenic, fluoride, iron, calcium etc.
Hence, with the constant deterioration in the quality of water and rise in impurities, it is now imperative to have a water purifier in our kitchen
The Mercy RO technology is based on double purification system.In this system water complete the RO process first then initiates the second process called ultra violates radiation process. In the first process we remove the solids by maintaining dissolved minerals. Then in the next process water is passed from ultra-violate rays in order to kill bacteria and virus. Between the 2 process TDS of water is maintained so as to maintain taste and minerals.
Ultra Violet (UV)Disinfection has been in the market for many years now.Some people also refer to this technology as electronic boiling.This technology successfully deactivates harmful micro-organisms like bacteria and viruses but fails to properly deactivate the more harmful ones – cysts. Also, if the water purified through this technology is stored for a long time, then there are chances that the deactivated micro-organisms may reactivate again. When used in combination with other filters (sediment and carbon),this technology is quite effective in removing all suspended impurities as well as some of the dissolved gases in water.But similar to Boiling, this technology has no effect on dissolved impurities such as rust,arsenic, fluoride, etc.
Reverse Osmosis (RO) Filtration
Reverse Osmosis (RO) technology is probably the best known purification technology to the mankind. It effectively removes all harmful micro-organisms such as bacteria, viruses and cyst. When it is used in combination with other filters (sediment and carbon), it successfully removes all other suspended impurities from water including dissolved gases and organic impurities. The biggest advantage of this technology is that it is able to remove more than 99% of dissolved impurities such as chemicals, rusts, salts of heavy metals, pesticides and insecticides present in water. Infact , RO is the only affordable technology to be able to remove dissolved impurities from water. Keeping in mind the disadvantages of RO technology, MERCY has invented a new technology called the MERCY Mineral ROTM Technology. This patented technology has all the benefits of the RO technology, while eliminating its limitations. MERCY patented MERCY Mineral ROTM Technology uses an innovative TDS (total dissolved solids) control valve which allows the user to control the amount of essential natural minerals present in drinking water. It ensures that the RO purified water does not have a bitter taste and the pH is maintained around 7. It also enables the user to adjust the amount of TDS in purified water according to ones taste. This technology is based on double purification wherein water after passing through RO, is also passed through Ultra Violet (UV) radiation and Ultra Filtration (UF). Secondary purification by UV/UF ensures that when the pores of RO membrane open up and allow harmful micro-organisms to pass through, they get deactivated/filtered out by UV/UF.
