Modelling heat transfer in sewer systems - towards a city-wide model for heat recovery from wastewater
Majority of the energy consumed for urban water services is used to heat tap water. In order to allow for a system-wide evaluation of heat recovery possibilities from wastewater, this paper presents a one-dimensional model that can describe temperature and flow rate variations in a sewer pipe. The model is applied to successfully predict downstream wastewater temperature for sewer stretches in two Swedish cities (Linköping, Malmö). The model can be used to study various heat recovery possibilities from wastewater. It can be easily integrated with models developed to generate flow rate and temperature profiles from households as well as standard activated sludge models for modelling wastewater treatment plants so that a system-wide heat recovery study can be made possible.
