Re-Use Waste from Reverse Osmosis (RO) Filter. Many of us use Reverse Osmosis Filters (RO filters) to purify Drinking Water, in areas with high TDS (Total Dissolved Salts) content in the Water. Around 75% of the Water fed into a RO filter, is wasted. Only 25% gets extracted as drinking Water.
The Difference between purified water and distilled water is that purified water has been filtered to certain specifations depending on whoever or whatever is filtering the water. It may include different minerals that naturally exist in water. Distilled water is what scientist use to do experiments or what you would put into your iron.
