Aqua America water treatment plant in Tiffin, Ohio, was built in the 1920s and is situated on the Sandusky River. The plant processes 3.4 million gallons per day and was facing challenges of producing high-quality drinking water. A full measure of seasonal variety, combined with the runoff from a thriving agricultural environment, caused the small-town water facility to constantly encounter adverse conditions. In an effort to remain compliant, Aqua America enhanced coagulation, but this increased sedimentation rates and exacerbated sludge blanket depths.

Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.
A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.
The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
