  • Modelling the viability of heat recovery from combined sewers

    Modelling of wastewater temperatures along a sewer pipe using energy balance equations and assuming steady-state conditions was achieved. Modelling error was calculated, by comparing the predicted temperature drop to measured ones in three combined sewers, and was found to have an overall root mean squared error of 0.37 K. Downstream measured wastewater temperature was plotted against modelled ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • The potential for thermal energy recovery from wastewater treatment works in southern England

    This paper asks how much heat could be recovered from wastewater treatment plants under UK climatic conditions, and can this heat be used effectively to reduce their carbon footprint? Four wastewater treatment sites in southern England have been investigated and the available heat quantified. Issues relating to the environmental, economic and practical constraints on how this energy can be ...

  • 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 ...
