Of course the best would be to run a nearly neutral rinse tank, but this requires some acid removal (or neutralisation).

Pollution Prevention in Rinsing

Countercurrent rinsing uses sequential rinse tanks in which the water flows in the opposite direction of the work flow (dirtiest to cleanest). Fresh water is added only to the final rinse station and is conveyed, normally by gravity overflow, to the previous rinse tank. Wastewater exits the system from the first rinse tank.D.I.
