Over the last several months, we have had difficulty with calibration of our pH sensors, particularly the pH adjustment sensor that controls pH in the range of 9.1– 9.5 for precipitation. Somehow the sensor still works well enough for us to achieve metal precipitation to maintain compliance, although our effluent’s metal concentrations are a little higher than in the past. We feel very uncomfortable continuing this way. Any ideas to help?

We can clean hot-rolled P&O; on that material the slimiest, oiliest stuff cleans just fine, but the seemingly cleaner CRS will not clean up with our alkaline cleaner. We are water break-free after phosphate because of the acidic nature of the stage, but two things are happening: One, we are compromising the effective stage dwell time of our third stage because it has to clean before it can deposit phosphate, and two, we are trashing our third stage with an excess amount of soils.
Read MoreLiquid To Powder
What would it take to convert a small liquid booth for powder application? Would simply replacing the typical fiberglass or poly exhaust filter media with some type of micron filter box/panel be sufficient? How likely is it that we can match our vendor’s powder coat finish/color with our own, taking into account the translucent nature of a gloss red? (We’d be uusing the same powder as the vendor)
