Abstract
Waste water discharged from a reverse osmosis unit served by a water feed line and producing potable water is returned to the water feed line for water conservation purposes. After periodic flushing of the reverse osmosis unit, the flush water may be returned to the water feed line or channelled to a drain. After each cycle of operation, any pressure differential between the water inflowing to and water outflowing from the reverse osmosis unit is relieved.
