Session 6: Responses to PFAS/PFOA

Abstract Number:


Audience members will learn simple solutions to achieve water and ‎waste reduction that are readily ‎implementable, plus learn creative ‎ways to reuse waste from case studies. Implementation of ‎‎strategies can reduce risks for a regulatory nonconformance (and ‎associated financial implications), ‎plus save on costs down to the ‎process level.‎


Managing Water Usage/Waste Management Minimization ‎

Improper wastewater management can lead to significant ‎consequences for surface finishers. Excessive costs for off-site ‎shipment, liability from regulatory requirements, and impacts to ‎production can quickly burn a hole in a plater’s pocket. However, ‎when waste minimization and wastewater management are ‎coupled, regulatory risks are reduced and financial benefits are ‎reaped.‎

This presentation will first cover typical water management ‎strategies easily implementable for surface finishers, including ‎simple opportunities to add instrumentation or controls at ‎wastewater-generating processes. Recommendations will be ‎provided on how to trend data to predict complications before they ‎occur, plus the benefits of identifying abnormal conditions ‎proactively. Lastly, creative marriages of waste minimization and ‎water management will be presented. One facility transformed an ‎aging wastewater treatment system to reuse waste etching solution ‎as treatment chemistry, adapting to keep up with production ‎demand plus eliminating an additive cost. Another facility ‎eliminated regulatory risk and continues to save 1.9 million gallons ‎of water per year after implementing a zero liquid discharge ‎wastewater treatment system.‎
