Thanks, Dave. As a start-up, we're trying to make it as cost effective as possible. That said, we also want to do it right. We don't want the possibility of the City/State/EPA coming down on us anytime in the future for contaminants being discharg

There are a few companies that sell the pressure senors and software to data-log and map the coverage and pressure of fluid spraying systems.However they tend to be expensive. If you would like the link please send me an email and I would be happy to

Why not toss a handful of the component that you're concerned about into your cleaner, clean them according to your board spec and the evaluate what happened?

Thanks everyone for the input. I think in our case Dave was correct in saying the temperature was the most evident casue to our foaming problem. I found out today from our maint. techs that temp. control has been an issue recently and now we know wha

Is the prewash water going to drain or being re-circulated? If you are re-circulating don't send all or a portion to drain (or your treatment system) even sending a small portion to drain and adding fresh will reduce foaming. You will pull more water

We've just acquired a batch washer at an auction, and want to install it as a closed loop system. The only problem is I have no idea where to turn or what to look for for a drain filtering system that will allow us to make it a closed loop system.
