News: The Union Environment Ministry has published a draft notification that effectively prohibits users from installing membrane-based water purification, mainly reverse osmosis, systems in their homes if the water has been sourced from a supply that meets the Bureau of Indian Standards’ drinking water norms.
Why?
The Ministry has issued this order to comply with an order of the National Green Tribunal (NGT), which has prohibited the use of reverse osmosis (RO) purifiers in places where total dissolved solids (TDS) in the supplied water are below 500 mg per litre.
Background
Why did NGT ordered a ban on RO filters?
The NGT had ordered a ban on RO filters on the grounds that they wasted water and that, in the process of removing salts, they often deprived drinking water of essential salts. RO while useful in reducing salts does not tackle bacterial agents or trace chemicals and manufacturers often claim that additional filtration is required to deliver potable water.
What are BIS regulations on drinking water?
How Does Reverse Osmosis Work?
Reverse Osmosis water purification process is accomplished by water pressure pushing tap water through a semi-permeable membrane to remove impurities from water. This is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water).
