Impacts of water re-use on drinking water treatment plant practices

Abstract

As populations increase, discharges of treated wastewater into streams and lakes make minimal time lag raw water monitoring more important in maintaining drinking water integrity. Of a more acute nature, discharges of partially-treated or untreated wastewater have profound impacts on treatment schemes practiced by drinking water treatment facilities. Introduction of anthropogenic contaminants, such as increased total organic carbon (TOC), microbial components, non-specific increases in chlorine demand, ammonia are some of the factors which negatively impact the treatment scheme. This presentation will address both of these scenarios as well as actual effects on a treatment plant in metropolitan Atlanta and the responses of the drinking water treatment plants to the disruptions.
