This wastewater treatment plant is located on the Ohio River in heavily industrialized northern Kentucky. The plant’s primary function is to disinfect municipal and industrial wastewater before introducing the water back into the Ohio River.

The plant had been using a UV system to disinfect its effluent, and although it was in good working order, issues arose due to the industrial loading. The UV system was unable to reliably meet mandated disinfection requirements. 

This case study details the successful switch to peracetic acid.
