"Optimization of the average R/O water purification system."
-Joanna Shruti Sundharam
The normal RO systems produce 4 times the waste, of the water it purifies. For 1 litre of pure water, 4 litres are wasted. In RO systems, water pressure is used to force water molecules through a very fine membrane leaving the contaminants behind. Purified water is collected from the "clean" or “permeate” side of the membrane, and water containing the concentrated contaminants is flushed down the drain from the "contaminated" or “concentrate” side.
Implementation details: Zero waste RO units are available, however problematic, as they can re-inject the concentrate waste water back into the water feeding the RO thus forcing the RO to work harder and shortening its service life. The contaminated water can be treated in such a way that it would be suitable for other purposes like 'dish-washing' etc.
