Around here that opens you up to some financial liability if ANY lead is found in the sewage, if they can't pinpoint the source. Every user over X lbs./month (dunno the specifics, just got this from our hazmat guy) is on the bubble for anyone else's

Our company uses a conveyorised aqueous cleaner to wash printed circuits after water soluble solder paste is reflowed. The system is closed loop with carbon and resin filters. The water eventually will get dirty. Can it be dumped? Treated? How do y

I am getting ready to purchase a spray fluxing system for a no-clean process. I have narrowed it down to the Nordson or Dover system. Does anyone have any experience with either. If so can you relate with me. I am a little leary of the Nordson be
