June saw annual meetings and conferences for two of the largest trade groups in surface finishing, as the National Association of Surface Finishers and the Chemical Coaters Association International held gatherings in Grand Rapids and Sarasota, respectfully. The Powder Coating Institute held its annual meeting in late May in Austin Texas.
We have an old wastewater pretreatment system for our metal finishing operation. The system contains two large air diaphragm pumps that transfer the wastewater from a holding tank to the flocculation tank before the clarifier. Since we are renovating the pretreatment system to extend its life, our team is arguing over whether to replace or keep these pumps.
A primer on this inexpensive and highly efficient process.
