Session 6: Responses to PFAS/PFOA
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.
