  • Investigating the interactions of decentralized and centralized wastewater heat recovery systems

    In the urban water cycle there are different sources for extracting energy. In addition to potential and chemical energy in the wastewater, thermal energy can also be recovered. Heat can be recovered from the wastewater with heat exchangers that are located decentralized and/or centralized at several locations throughout the system. It can be recovered directly at the source (e.g. in the ...

  • Assessment of organic micropollutants occurrence in treated wastewater using heat shock protein 47 stress responses in Chinese hamster ovary cells and GC/MS-based non-target screening

    Combining bioassays and analytical chemistry screening is a powerful approach to assess organic micropollutants which are the main contributors to toxic potential in complex mixtures of treated wastewater (TWW). The aim of this study was to perform a comprehensive toxicity assessment of treated effluents using stress response bioassays and then to assess the occurrence of the organic ...

  • BLOOM Wastewater Sensor - Case Study

    Water is an integral input and vital strategic resource for the Ontario Food and Beverage Processing Sector. Water plays a variety of diverse and convergent functions. It is used for heating and cooling, blending, washing and rinsing, convey- ing, cleaning and sanitation – as well as being a vital product ingredient. However, the use of water inevitably leads to the generation of wastewater ...


  • 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 ...


  • Heat From Wastewater

    When it comes to using wastewater heat from channels, provision and evaluation of hydraulic and thermal wastewater data is urgently needed prior to planning and implementation of facilities. Knowing the wastewater temperatures as well as the flow rates - particularly as dry weather discharge – is an indispensable component. It is therefore essential to carry out preliminary measurements ...
