  • World Water Magazine: Tackling Wastewater Treatment Odors and Hydrogen Sulfide Emissions in the Middle East

    With round-the-year hot temperatures, wastewater treatment facilities in the Middle East have to deal with a wide-range of odor challenges. In addition, high-levels of hydrogen sulfide emissions can be problematic due to excessive heat, and potentially be dangerous to plant employees and neighboring residences. With summertime temperatures often above 100 degrees Fahrenheit, sewage also ...

  • Nutrient transfer by runoff from sewage sludge amended soil under simulated rainfall

    Wastewater sludges are used in agriculture as soil amendment and fertilizer, with regard to their organic matter and nutrient content. However, availability of nitrogen and phosphorus from sludge-amended soils and their transfer in runoff may lead to eutrophication of downstream surface water. The aim of this study is to establish and compare the effect of two different sludges on these ...

  • 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 ...

  • Sewage Treatment Plant reports success with HACH LANGE LDO

    Between 60 and 70% of the energy consumed by sewage treatment plants is used to aerate the activated sludge. Strategies aimed at reducing energy consumption are therefore usually focused on optimising the oxygen transfer into the aeration tank. All control systems are based on exact and precise measurement of the oxygen concentration. For process engineers, therefore, the issue is not whether but ...


  • Deep and Dirty - Derby Sewage Treament Works Inlet tank

    Derby STW had a significant problem with float switches 'ragging-up' in this very large inlet works. Other ultrasonic equipment failed and the customer did not believe an ultrasonic solution could work.....until Pulsar became involved. Pulsar Process Measurement supplied non-contacting ultrasonic level measurement equipment into the main transfer pumping station at Severn Trent Derby STW, in an ...

  • Quebec recovers heat energy from sewage in Baied`Urfe

    Energy recovery from municipal sewage and greywater offers cities a new reliable resource.  Erwin Schwartz of DDI Heat Exchangers Inc. reports on a novel application of rectangular, wide-gap heat exchangers that has worldwide potential. The Canadian company DDI Heat Exchangers Inc. installed, with the support of the Quebec provincial government and municipal sewage authority, the first ...

  • Paraben resistance in bacteria from sewage treatment plant effluents in India

    Parabens, the antimicrobial preservatives used in cosmetics, food and pharmaceuticals, are often detected in the aquatic environment. Generally, sewage treatment plants (STPs) receive community sewage containing parabens, which are ultimately released into streams/rivers. In this study, bacteria in STP effluents were evaluated for their resistance to parabens. The susceptibility was in the order ...

  • Concentration of facultative pathogenic bacteria and antibiotic resistance genes during sewage treatment and in receiving rivers

    Whereas the hygienic condition of drinking and bathing water by law must be monitored by culture-based methods, for quantification of microbes and antibiotic resistance in soil or the aquatic environment, often molecular genetic assays are used. For comparison of both methods, knowledge of their correlation is necessary. Therefore the population of total bacteria, Escherichia coli, ...

  • Practice report - Process analysis aeration control NH4D SC ISE ammonium probe

    The idyllic scene in the photo above is deceptive, as the tranquil oxidation ditch of the Rommerskirchen-Villau sewage treatment plant (PE 5,000) could be more sparing with its oxygen transfer. The plant operator, the Erftverband(a wastewater disposer with its headquarters in Bergheim), has therefore decided to improve its operating efficiency. Many other small and medium-sized plants are in a ...


  • Mono is the key to york house problems

    The site, York House Holiday Park in the heart of the tiny hamlet of Balk near Thirsk, was experiencing problemswith the submersible pumps that are installed to handle the sewage and waste water from the caravan site.
