Water after PCB batch wash | 28 September, 2023

I've been looking for information on how, if at all, any of you treat water after a pcb batch wash. In particular, we have a Trident LD machine, using Zestron cleaning chemical. We have a carbon tank and two mixed bed media tanks as well as two 5 micron filters we use before discharging to city sewer. Is anyone else using this much filtration, or are we overkill and can cut back? Between the filtering service and DI system, we go through a lot. I've already talked with the city and DNR with water discharge, and since we don't manufacture PCB's, we only assemble, they don't have specific standards for us.
