  • Determining The Kinetics Of Biotransformation Of Estradiol And Estrone During Transit In Sewage Collection Systems

    Although wastewater treatment does remove a significant amount of estrogens, some estrogens survive wastewater treatment and enter surface water through wastewater treatment plant effluents. Estrogen concentrations in the ng/L range have been well documented in the effluents of sewage treatment plants all over the world. Estrogens are known to cause estrogenic responses in aquatic species, which ...

  • Pollutants in Urban Wastewater and Sewage Sludge

  • Near-infrared spectroscopic assessment of contamination level of sewage

    We examined the use of near infrared (NIR) spectroscopy as a rapid technique for the evaluation of sewage quality. Influent water samples, primary sedimentation tank water samples, and final effluent water samples were collected from sewage treatment facilities in Nagoya, Japan and their NIR spectra obtained. Partial least squares (PLS) models for total phosphate (TP), total nitrogen (TN), ...

  • One Forcemain – Multiple Sewage Pumping Stations

    The sewage collection system for the community of Port Perry Ontario includes several sewage pumping stations conveying wastewater to the existing aerated sewage lagoons for treatment.  Initially the system originally included two sewage pumping stations pumping from the Community directly to the lagoons; the Water Street Pumping Sewage Station and the Cawker’s Creek Sewage Pumping Station. ...

  • Case study - Vestfjorden Sewage Plant (Veas)

    In Norway’s largest sewage plant, Veas in Oslo, Filtralite* has proven extremely durable as both bio substrate and sludge filtering medium. After 25 years of operation with daily back flushing there is no need for replenishing. A river of sewage of maximum 11 m3 second runs in a 42 kilometre underground tunnel, collecting sewage from Oslo centre to Slemmestad in ...

  • Real Time Control of the Sewage System in St Malo

    Saint-Malo is an extremely attractive and popular seaside resort on the north coast of Brittany in France. Covering 1,400 hectares, the local population of 50,000 increases to 120,000 in the tourist season. One of the distinguishing features of this part of the Channel coast is a very high tidal range – 14 meters from low to high, with a potential impact back through the sewer network. Combined ...

  • Estimating the costs of collective treatment of wastewater: the case of Walloon Region (Belgium)

    This paper contributes to a better understanding of costs for collective wastewater treatment in the Walloon Region (Belgium). Based on a large set of data, unit costs to population equivalents are modelled. Considering investment as well as exploitation costs, the model includes not only wastewater treatment plants but also collector and sewage networks in an integrated approach at the technical ...

  • Evaluation of the impact of industrial sewage pollution on marine benthic communities

    A survey was performed to assess organic pollution, water properties and the marine benthic community. The need to assess the environmental status of marine and coastal waters encouraged the design of specific biotic indices to evaluate the response of benthic communities to human-induced changes in water quality. In this study of the benthic community structure in Ghanam Creek surrounding an ...

  • Phyto-dewatering of sewage sludge using Panicum repens L.

    Experiments in the field environment have been conducted to study the growth of Panicum repens L., an aquatic plant, in the sewage sludge matrix. The experiments were also carried out to investigate the ability of this plant to dewater sewage sludge to increase the capacity of conventional drying beds. In addition, the ability of Panicum repens L. to reduce the sludge ...

  • Mass balance analysis of triclosan, diethyltoluamide, crotamiton and carbamazepine in sewage treatment plants

    The behavior of antibacterial triclosan, insect-repellent diethyltoluamide (DEET), anticonvulsant carbamazepine, and antipruritic crotamiton was investigated at two sewage treatment plants (STPs) to clarify their complete mass balance. Twenty-four-hour flow-proportional composite samples were collected from the influent and effluent of primary and final sedimentation tanks, a biofiltration tank ...

  • Treatment of the city of Oudenaarde (Belgium) sewage discharge canal case study

    Executive Summaryc A canal responsible for carrying sewage away from the City of Oudenaarde to the Scheldt River was partially dammed in 1965 leaving an area of open water of approximately 1 hectare (600 meters by 17 meters). As the canal was only partially dammed, water from the canal continued to flow into the Scheldt River. Two large municipal sewage collection discharge pipes ...

  • Using FIMS to determine mercury content in sewage sludge, sediment and soil samples

    Tim Flow Injection Mercury System (FIMS) is a dedicated system that integrates flow injection mercury cold vapor generation with a very sensitive detector. The exceptional system stability and the long path measurement cell provide instrumental detection limits as low as 5 ng/L using a sample volume of 5(H) jxL. The improved sensitivity of the FIMS permits sample dilution, therefore reducing the ...

  • What too much water can do to your collection systems

    In areas with a high water table, or for cities more prone to flooding, your underground infrastructure can become inundated with groundwater and stormwater. And despite stormwater systems being built for this type of collection, there are a number of things that can go wrong for both types of collection systems underground—and above ground—that can lead to contamination or degraded ...
