The reuse of industrial wastewater is becoming increasingly common because of water shortages, environmental necessities, economic incentives, government mandates, and societal desires. PRO-TEC Coating Company, located in Leipsic, Ohio, is the world’s largest hot-dip galvanizing and galvannealing facility producing quality-critical corrosion resistant steel for the automotive, appliance, and construction industries. PRO-TEC successfully implemented recycling of their oily and metal containing wastewater to meet quantitative discharge limits imposed upon them by the EPA.
