Case History: Optimization of a Wastewater Treatment Membrane System Designed for a Heat Treating Metal Finishing Facility

摘要

An integrated manufacturing facility involved in heat treating and metal finishing operations was experiencing poor waste treatment membrane filtration. By optimizing the chemical pretreatment of the wastewater, the following benefits were realized: improved flux rates, reduced regeneration cycles, decreased membrane operating pressures, and improved sludge dewatering of the reject water.
