Why is RO banned in Some Countries?

The main problem of the water purifiers that have caused the ban of water purifiers in different parts of the world is that during the purification method almost 70 to 80% of the water gets wasted. With the indiscriminate use and increasing popularity of the RO system, a huge amount of water is wasted daily. Also, demineralization is not necessary if your area has a TDS of 500 PPM in each liter of water.

But the problem is that people are installing and using RO water purifiers without knowing this fact and testing the TDS of their area. To fix this problem in India 2024 , National Green Tribunal (NGT) has asked the central government to restrict the RO water purifiers where the water supply contains less than 500 TDS.


Why have Some Countries Banned RO Water Purifiers?

Other reason for Banning RO Water Purifiers

Other than to waste away too much water, the RO system without a TDS controller, also removes the essential salts that are present naturally in the water. Water found in nature contains a large amount of trace and essential minerals.

If you install a water purifier with RO process in an area that has a TDS of less than 400 mg per liter, then after the purification process, the TDS will drop to 45 to 50 mg per liter. This low TDS will cause the water to turn acidic, will taste bad, and will prove to be harmful to your health in the long run.

Thus, it is a better idea to ban these purifiers with areas of less than 500 TDS. For purification of water in those localities, other types of machines with UF and UV purification methods will be the best.


Is it the end of the RO water Purifiers?

No, this is not the end of the RO water purifiers. These devices will still be needed in the places where the source of water for drinking purposes is the sea or salty water. It can also be used where high TDS is present in the water supply or people collect water from the bore well or the ground level. Here this machine is compulsory to implement as the water might contain high industrial pollution, pesticide, or different chemical contaminants.

The final law for banning is still not framed in India 2024 , but still, it can be expected that the users will not be charged any fine or prosecuted for the installation of the RO system. But if anyone complaints about the violation of the law to the environmental industry or the pollution control board of India, then they may levy a fine on the user or even confiscate the machine. You can find here the best RO Water Purifier in India 2024 has the maximum potential to purify water.

However, the new law will be tougher on the manufacturers for the violation or production of the RO machines. The manufacturers also need to make sure that all the devices will not waste more than 40 to 50% of the water during the purification processes. This means that the RO water purifiers with the new technology will be costlier to meet all the new standards of the ministry.


Unwarranted Ban of the RO water purifiers

Sources from the water purifying industry states that any kind of implementation of the RO ban is unwarranted. The main argument for this statement is that even if the water supply of an area contains a TDS of less than 500 mg in each litre, it might contain heavy metal contaminants also like microplastics, and pesticides. This type of water will not be purified by any type of machine other than RO.

They have also said that most of the RO water purifiers have the ability to retain 55 to 60% of the water while some of the commercial RO water purifiers have even more recovery rate of the water. They have concluded by saying that a ban on the use of the RO water purifiers will not only have an adverse effect on the sector but will have an immense effect on the packaged drinking water and pharmaceutical industries as well.
