  • Future-oriented further developments: wastewater heat utilization plants with a return on investment (ROI) of 2 - 6 years

    Sewage is dirty and stinks. Out of sniffing distance – out of mind. Up until the 1980s sewage was taboo and not given the attention it deserves. One cold winter morning in 1988, 23 years ago, Urs Studer stopped beside a steaming manhole cover and wondered how such a source of heat could go untapped. Ever since he has been dedicating himself intensively to the recycling of sewage heat. At ...

  • Turbo Blowers made by AERZEN for Base Load, Delta Hybrids for Peak Load - Step by Step Towards the Ideal Sewage Plant

    Thanks to the reduced sewage duty resulting from basic changes to the aeration basins in 2008, modification costs of € 1.3 million were amortised after only three years. Replacement of the two existing turbo compressors with two new Aerzen rotary lobe compressors of series Delta Hybrid, led to an additional energy saving of approximately 13 % of process air generation. Since then, the entire ...

  • Joint German-Polish sewage plant satisfied with Allweiler pumps after 12 years

    An example of successful German-Polish collaboration In May 2010 the Gubin sewage plant celebrated its twelf-year anniversary. This plant processes wastewater from the cities Guben and Gubin, located on opposite sides of the Neisse River. It is the only German-Polish project of this type to operate successfully for the long term. Major elements of the plant include 17 progressing cavity ...

  • Saline sewage treatment and source separation of urine for more sustainable urban water management

    While energy consumption and its associated carbon emission should be minimized in wastewater treatment, it has a much lower priority than human and environmental health, which are both closely related to efficient water quality management. So conservation of surface water quality and quantity are more important for sustainable development than green house gas (GHG) emissions per se. In this ...

  • Florida Waste-To-Energy Plant Has Composting Officials Fired Up

    Plans for a renewable energy facility in central Florida which will burn horse stall bedding as well as other wastes is raising concerns among officials from composting companies in the region, who are questioning everything from the cost-effectiveness of the multimillion dollar plant to whether it will actually help alleviate groundwater pollution problems. “The proposed gasification plant is a ...

  • AERZEN provides energy efficient process air generation in the Kötz wastewater treatment plant

    The Kötz wastewater treatment plant, located a few kilometres south of Günzburg, was designed for a population equivalent of 45,000. About 20,000 inhabitants are connected at present. Due to the additional discharge of industrial wastewater, the average daily load corresponds to a population equivalent of about 35,000. The wastewater treatment plant works according to the ...

  • Global implementation of two shared socioeconomic pathways for future sanitation and wastewater flows

    Households are an important source of nutrient loading to surface water. Sewage systems without or with only primary wastewater treatment are major polluters of surface water. Future emission levels will depend on population growth, urbanisation, increases in income and investments in sanitation, sewage systems and wastewater treatment plants. This study presents the results for two possible ...

  • Efficiency of Process Measurement Technology for Determining Nutrient Parameters – Yesterday, Today and Tomorrow

    Abstract The costs and benefits of process measurement instruments in sewage treatment plants were the subject of intensive debate in the 1990s. Cost-benefit studies, comparing the potential savings in energy, consumables and personnel with the additional costs of using the instruments, resulted in recommendations specifying the minimum sewage treatment plant size at which the use of such ...


  • 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 ...

  • Drinking rainwater and reusing wastewater

    Decentralized systems for drinking water processing could make a significant  contribution to the Millennium Development Goals. With the water concept in “self”, Eawag has demonstrated that membrane technology offers the chance to do just that. Lack of drinking water hygiene is one of the main sources of disease transmission worldwide, and in many situations centralized plants ...

  • Transportation of digested sludges over extreme distances

    Sludge is a residual product of sewage treatment that, as a rule, is digested and concentrated. In larger processing plants, it is dehydrated, partially dried and subsequently utilised in other processes. This usually takes the form of incineration and subsequent use as an additive to building materials by the cement industry. In the sewage treatment plant (STP) of the local authorities ...

  • High quality bathing water protects human health

    The sewage treatment plant of Biarritz, France faced severe issues with inflowing water during heavy rain fall, resulting in untreated wastewater being diverted directly into the sea, alongside public beaches. A fast and reliable disinfection of the flow was needed. Kemira installed DesinFix disinfection technology which is designed for water reuse, and to handle such problematic flows ...

  • Benefits Realized Through Asset Management Practices at Eastern Municipal Water District

    In late 1999, Eastern Municipal Water District’s (EMWD) Board of Directors and Senior Managers recognized the importance of asset management in providing service to its customers and directed staff to implement a comprehensive asset management program based on best practices. The District recognized early on that total organization commitment was necessary to achieve success in asset management ...

  • Upgrading effluent quality with a plastic media based process
