Effect of rainfall characteristics on the sewer sediment, hydrograph, and pollutant discharge of combined sewer overflow.

Journal of Environmental Management, 2021
Significant management needs raised in urban sewer system to facilitate urban resilience to rainstorm. The work investigated the effects of temporal evolution of rainfall on hydrograph and pollutant discharge of CSO over an intensive observation period ...

Identification of new eligible indicator organisms for combined sewer overflow via 16S rRNA gene amplicon sequencing in Kanda River, Tokyo.

Journal of Environmental Management, 2021
Fecal indicator bacteria (FIB) are commonly used to evaluate the pollution impact of combined sewer overflows (CSOs) in urban rivers. Although water quality assessment with FIB has a long tradition, recent studies demonstrated that FIB have a low ...

Priority pollutants in wastewater and combined sewer overflow

Science of The Total Environment, 2008
Implementation 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 ...

Elimination of micropollutants in four test-scale constructed wetlands treating combined sewer overflow: Influence of filtration layer height and feeding regime.

Water Research, 2020
Municipal wastewater can contain large amounts of organic micropollutants. Some of these substances are harmful to the environment, even at low concentrations, e.g.

Enhanced combined sewer overflow treatment by rapid magnetic flocculation–magnetic sedimentation: Efficiency and mechanism

Environmental Science
Magnetic flocculation is gaining interest as a potential method for treating combined sewer overflows (CSOs) because of its short settling time, small footprint, and dense sludge.

Unraveling the synergistic mechanisms of coagulation combined with oxidation for the treatment of sewer overflow: The interaction between iron species and NaClO.

Journal of Hazardous Materials
During wet weather, sewer overflow pollution can pose a serious threat to surface water. In order to reduce the impact of overflow discharge on receiving waters, ferric chloride (Fe(Ⅲ))/potassium ferrate (Fe(Ⅵ))/polyacrylamide (PAM) coagulation (Fe(Ⅲ)/Fe(

Reduction of micropollutants and bacteria in a constructed wetland for combined sewer overflow treatment after 7 and 10 years of operation.

Science of the Total Environment, 2019
Repeated investigations on constructed wetlands for the treatment of combined sewer overflows, also named bioretention filters or retention soil filters, are necessary to provide information on their long-term performance.

Strategies to Control Combined Sewer Overflows

Journal of Environmental Engineering, 1988
This 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 ...
