Mitigating the Impacts of Combined Sewer Overflow to an Urban River System via Web-based Share-vision Modeling
Storm water overflow from the combined sewer system might result in a sudden devastating impact to the local ecosystem in an urban river environment. In order to assess overflow pollution load during tropical rainfall, a web-based share vision modelling system is organized and designed in this study to investigate the resultant water quality impacts from both spatial and temporal aspects simult...

15 صفحه اولEFFECTS OF COMBINED SEWER OVERFLOWS ON A PERIURBAN STREAM ECOSYSTEM : Methodological approach
Here we develop from a long term field experiment an assessment method of interstitial fauna resilience to combined sewer overflows (CSOs) effect. We address the case of “small water courses” for which the ratio of CSOs to natural flow can be 1 to much more. Biotic material was collected in the benthic and hyporheic layers. Biotic material focussed mainly on oligocheates species whose diversity...
متن کاملEvaluation of Ecotoxicological Risks Related to the Discharge of Combined Sewer Overflows (CSOs) in a Periurban River
Discharges of Combined Sewer Overflows (CSOs) into periurban rivers present risks for the concerned aquatic ecosystems. In this work, a specific ecotoxicological risk assessment methodology has been developed as management tool to municipalities equipped with CSOs. This methodology comprises a detailed description of the spatio-temporal system involved, the choice of ecological targets to be pr...
متن کاملTreatment of combined sewer overflows using ferrate (VI).
This paper presents the results of a study conducted on the treatment of combined sewer overflows using ferrate (VI) [Fe (VI)]. At a Fe (VI) dose of 0.24 mg/L, total chemical oxygen demand (TCOD), soluble chemical oxygen demand (SCOD), total biochemical oxygen demand (TBOD5), soluble biochemical oxygen demand (SBOD5), total suspended solids (TSS), volatile suspended solids (VSS), total phosphor...
