Priority pollutants in wastewater and combined sewer overflow
Science of The Total Environment, 2008Implementation of the European Water Framework Directive and its affiliated directives requires Member States to improve their understanding of priority pollutants (PPs) in urban areas and obviously within wastewater systems. As a direct consequence, this study is intended to furnish data on both PP occurrence and the significance of concentrations in ...

Strategies to Control Combined Sewer Overflows
Journal of Environmental Engineering, 1988This study compares five strategies for controlling combined sewer overflows. All these strategies could be used in real time. The criterion for the ranking of relative effectivenesses of these strategies is their ability in protecting the receiving stream water quality, with impacts of overflows being measured by variations of a water quality index ...

Identification of In-Sewer Sources of Organic Solids Contributing to Combined Sewer Overflows
Environmental Technology, 2002Previous research has shown that combined sewer systems are the main source of particle and organic pollution during rainfall events contributing to combined sewer overflow. The aim of this article is to identify in an urban catchment area called "Le Marais", in the center of Paris, the types of sediments that are eroded and contribute to the pollution

UV Disinfection of Wastewater and Combined Sewer Overflows
2017Municipal wastewater contains bacteria, viruses, and other pathogens that adversely affect the environment, human health, and economic activity. One way to mitigate these effects is a final disinfection step using ultraviolet light (UVL). The advantages of UVL disinfection, when compared to the more traditional chlorine, include no chlorinated by ...

Detention Storage Volume for Combined Sewer Overflow into a River
Environmental Technology, 2002This article discusses the storage volume needed in a combined sewer system tank in order to preserve the water quality. There are a lot of design criteria which do not take into account the conditions of the receiving water, and as a result are inappropriate.

Comprehensive assessment of combined sewer overflows in Slovakia
Urban Water, 2002Combined sewer systems in Slovakia were evaluated during a three-year joint research project of the Water Research Institute and the Department of Sanitary Engineering of the Slovak University of Technology. First results of the comprehensive assessment are presented in the paper.

Evolutionary Optimization of Combined Sewer Overflow Control
World Environmental and Water Resources Congress 2009, 2009Model predictive control (MPC) is coupled with a real-coded Genetic Algorithm to predict a decision sequence that minimizes combined sewer overflow (CSO) volume for a 3-hour rainfall event over a hypothetical sewer system. Rainfall is transformed to overland runoff through the cell model which depicts each sewershed (draining to an overflow dropshaft ...

High-Rate Disinfection of Combined Sewer Overflow
Global Solutions for Urban Drainage, 2002Wet-weather flow (WWF), including combined-sewer overflow (CSO), sanitary-sewer overflow, and stormwater (SW), is a significant contributor of microbial contamination to surface water and ground water. By using effective wastewater or SW disinfection, introduction of pathogen contamination into receiving waters can be greatly minimized.
