reverse osmosis deionization
Is there any use for the waste water that comes out of a reverse osmosis deionization water filtration unit?
Well, that would depend greatly upon what sort of water you are deionizing.
If, for example, you were making drinking water from sea water, the waste water could be further dehydrated via evaporation and sold as sea salt for a very good price.
If you were purifying municipal water for some biological purpose, the waste water would not likely be of much use because the municipal treatment plant would likely have taken out almost everything already and add only a bit of chlorine in the form of sodium hypochlorite or calcium hypochlorite or some such. The clorine would likely damage your reverse osmosis membrane, so there would be some sort of pre-treatment with something like sodium thiosulfate to neutralize the chlorine before it reached the reverse osmosis membrane, so your waste water would end up contain a mixture of sodium and/or calcium chlorides and sodium and/or calcium sulfates, which I don’t imagine would be of much use to anyone, but then I don’t know everything . . .
A third example: If you were purifying water from a relatively unpolluted surface water source, say a cleanish lake or river, my guess is that the waste water would make a pretty darned good fertilizer for agricultural use.
