All the impurities are collected in the filter membranes themselves and stored until exhausted and then replaced.

if the waste water is returned to the supply tank or source that water will keep collecting reject material and get increasingly dirty and the efficiency of the membranes will suffer.

I think you need to read my post again. Rejected/waste RO water has not been though the system. There's no "dirt" added - it never made it into the filter.
i am assuming that the reject water is not dumped on the ground nor do you allow it to fill up your grey water tank but reintroduce it to the supply tank. that is the one problem with RO, an excessive amount of water is rejected and if not reclaimed, wasted.
