you can boil RO water.
You can freeze RO water.
You can use it the way you like.
Why boil to sterilize when RO has done the same already?
No need to boil the RO water & it’s a simple wastage of energy. We are carrying out the RO process to mainly reduce the TDS & completely eliminate the bacterial contamination. Remember the RO membrane will not allow the bacteria & virus to pass through. So drinking RO purified water directly without boiling is safe. One should ensure that the RO membrane is not ruptured, & some quantity of water is passing through it without membrane separation. To ensure the same, it is better to conduct a bacteriological analysis of the RO water once in 3 months to understand faecal contamination’s. If E-coli population is higher, change the RO membrane.
Is it harmful to boil RO water before drinking?
Not harmful but pointless.
Idea of boiling is to remove salts and bacteria. RO followed by UV/O3 does the same hence there is no use boiling again
Can we boil RO water and use it for cooking?
Sure, but you don’t normally use RO water for cooking because it is more expensive than tap water, and doesn’t taste as good as tap water.
Is it safe to boil RO filtered water?
Yes, it is safe to boil RO filter water. If one boils the water after doing the reverse osmosis these microbes would be killed and can be removed from the water. Another thing is RO takes care of 90-95% of the chemical contaminants in water. Some of the remaining can be removed by boiling the water. So, yes it is safe to boil RO filtered water.
