Description

Currently, chlorine is the standard chemical used for the disinfection process in storm and wastewater treatment. Due to environmental complications involved in chlorine usage, peracetic acid (PAA) has been proposed as an alternative. Properties such as a faster decay rate and lack of toxic byproducts allows for the chemical removal step to be eliminated, saving time and resources. The goal of this study is to perform baseline testing to quantify loss of PAA under varying conditions. Different types of sands/soils as well as filtration processes could interfere with the efficacy of PAA and must be considered when calculating proper input rates of the chemical for large scale treatment plants. In the end, water mixtures with higher nutrient demands and organic content led to a higher PAA demands, resulting in less PAA availability for disinfection. By standardizing PAA requirements based on the physical and chemical properties of stormwater influent, this alternative to chlorine could be implemented in combined sewer systems.
