Wastewater Heat Articles

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 ...

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 ...

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 ...

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 ...
