Arresting Indoor Air Quality Criminals in Metal Finishing and Chemical Tanks
These so-called ‘criminals’—indoor air quality criminals, that is—can escape from open surface tanks causing irritation or harm to operators.
Engineering, architecture and consulting firm, Burns and McDonnels' Angela Vawter has an interesting take on ways to improve air quality in metal finishing operations, and also for any shop which has chemical tanks:
"When you think of criminals, the first thing that comes to mind probably isn’t humidity or hazardous mists and vapors. But these so-called ‘criminals’—indoor air quality criminals, that is—can escape from open surface tanks causing irritation or harm to operators, as well as corroding the surrounding building structure and supporting utility systems. Properly ventilating exhaust and supply air of open surface tanks is key to thwarting these fugitives before they can inflict damage—and can ultimately save a company a whole lot of trouble."

EPA Readying Fall Nationwide PFAS Survey of Metal Finishing Industry to Inform New Water Discharge Rule
NASF continues discussions with US EPA on the agency’s plans for a nationwide survey of the metal finishing industry on its use of PFAS. NASF plans to review the draft survey and provide feedback to the agency prior to its distribution. Surveys will likely go to a wide range of job shop and captive operations and are scheduled to be sent out in the fall.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 5th Quarterly Report
This paper covers a research grant at the University of Georgia - Griffin on developing electrochemical approaches to remove PFASs present in plating wastewaters, under the direction of Professor Qingguo (Jack) Huang. This fifth quarter report assessed eight PFAAs most commonly found in wastewaters, by electro-oxidation with a Ti4O7 anode across a range of anodic potentials in solutions of different compositions and at varying operating conditions.
