    Are you using RO based water purifiers in your home?

    National Green Tribunal (NGT) has prohibited the use of reverse osmosis (RO) water purifiers in places where total dissolved solids (TDS) in supplied water are below 500 mg/litre.

    Water quality association of India, the makers of water purifiers had moved Supreme Court for a stay of NGT order.

    The SC declined to intervene and NGT is directing the Environment Ministry to ban the installation of membrane-based water purifiers all over India. The reason for this ban is that if you are getting tap water with TDS between 500mg/littre to 1200 mg/littre as per the bureau of India standards (BIS), why you need water purifier. You are removing the dissolved solids required by your body, from water with these machines. Moreover, if you take water from these purifiers, approximately three times water will be wasted.I am collecting this high TDS water and using separately.

    The draft resolution is ready to ban these water purifiers by the Environment Ministry. They are seeking public opinion till 30 days.

    You can air your view. Later it will become a law.

    This is fun news. When we are getting the pure and safe tap water for drinking, then what is the need for RO purifier says the argument? But who will ensure the safety of tap water which is supplied through underground pipeline going through the manholes of solid waste and other contaminated place and who is checking the validity of pure water being supplied? And during the rainy season, we see the drinking water turning to a red colour as the soil sediments of stormwater also mingling with the pure water. So to avoid this people are using the RO purifier which can clean the bore water to drinkable water.

    I am for it. RO is required only for the waters having fluoride more than its limit in water. You can't remove fluoride by any other way than RO. But if the TDS is within in the range and if there is no fluoride above the standard limit, RO is not a requirement. In fact, there are many negative points about it. RO water is without any minerals and that will not give you any energy. That is why some people add minerals again to RO water. Water wastage is very high in this process. Instead of using RO plant we can have just ordinary filters where suspended solids and undissolved solids will get removed and all the minerals will be there in the water. But if the total dissolved solids are more we can use ordinary water softners where you will not get any wastewater and the dissolved solids will be there to some extent. As a matter of fact, RO plants were given more importance for the promotion of the product keeping the interest of the manufacturers. It is good if the government is banning them and promoting water softners.

    Why RO purifiers were alowed all these years? Why the authorities did not do reserach all these years?
    The fact is that , every political or administrative decision is taken subject to some kind of pressure from some lobby. Now the lobby opposite to or rival to the RO lobby has suceeded in pressurising. That is it. This also can be changed later if some other lobby becomes dominant and comanding.

    It is a fact that if the municipal tap water is clean, filtered amnd suppied with the permitted parameters,then no water purifier is required. But the pipes carying water may become contaminated by various reasons. Hence some kind of puifier/filter is needed as per the quality of water available. But how a normal person can be sure of the water quality? So he does not take any chance. He falls for the advertisements and uses a RO purifier.
    Moreover, in many cities, tanker water is the main source or a supplementary source as the municipal water supplyis absent or inadequate. So a water prurifier is needed. The better is an RO purifier.
    If people suffer from mineral(salt) deficiency then supplements are available cheaper.(Definitely not as costly as an unnecessarily flouride fortified edible salt)

    Everything is commercial. Whom to trust we do not know. Paid and doctored research results are being publicised. They arethen given support by biased/paid media . Then it is promoted as 'scientific data'. Anyway we ordinary people are always at someone's command directly or indirectly.

    Note: Yes, I am using RO water purifier for since a decade at least.

    PS: Salt with flouride is also not a necessity in most parts of the country, and in some places it is more dangeous also. But then why govt is not banning that? The support lobby is still powerful and the oppposite lobby is not at all there or weak.

    Rider question: How 'mineral' waer or packaged water is made and allowed? What is its TDS? What is the water loos i that during puriication?

    Water purifiers remove some of the wanted minerals but at the same time they remove the disease causing impurities also. So there are pros and cons of the situation. An ordinary water purifier might also serve the purpose in place of the RO and that can be seen by the user. Banning of the RO is a big step taken by the concerned agencies but we have to provide an equivalent safety net for the drinking water otherwise simply removing RO will nor serve the purpose. Earlier some people were using boiled water to remove the harmful things from it. At that time that was considered the best option.
    Knowledge is power.

    No we are using the normal version and that is more than satisfactory. RO type of plant may give more safety but at the same time it is told that it removes even the good minerals from the water. So this point is to be understood clearly before going for RO.
    Thoughts exchanged is knowledge gained.

    One important thing we have to note here is that BIS norms are voluntary for public agencies such as water boards of different states and mandatory for private agencies those who make bottled water. Mumbai is the only city in India getting good quality BIS standard water. Delhi is the least. NITI Ayog says 70% of supplied water in India is contaminated.
    I think it is everybody's responsibility to persuade the Authorities to upgrade and supply BIS standard water to everybody. Let us hope the Jal Shakti mission, which got substantial fund allocation in this budget will be able to do it.

    Actually it is usually not very healthy for a human body to consume water that is purified with Reverse Osmosis (RO) water purifiers. We know that there exists various required and as well as essential nutrients dissolved in water. Those are surely required by the human body. Using water purifiers, it minimize the content of those important nutrients dissolved and ultimately the quality of water decreases. Thus now a days Human body is getting deprived of those nutrients.
    For the places where water comming out is really pure, like in hilly areas, one can use the candle purifiers for better use of the natural water. With this all the essential nutrients remains dissolved in water and one can consume a nutrients rich water.

    While considering the total dissolved solids present in the wate, such contents such as Calcium, Magnesium, Iron etc provide essential nutrients to our body. Hence the depletion of those essential materials in the process of RO would have detrimental effects on our body system. If there is proper water treatment of the water being supplied to the consumers and no contamination occurs during the transmission of such supplied water, we can use the same safely. But then we have to ensure that arsenic, fluorides and other toxic elements have been removed effectively for the safe water consumption.
