Does a reverse osmosis system have to produce waste water in order to be effective?
Or can it purify water without producing any waste water and if so where do the impurities go?
Reverse osmosis does not have to produce waste water at all, but in that case the filtering system gets clogged in minutes. So, the waste water is produced not in process of reverse osmosis, but in processes of cleaning the filters. All the impurities are held in filter system, until washing, when they go to the washing water, which gets polluted.

The sluged water is expelled via separate tubing to the waste drain of the house.
