A mathematical model to predict the effect of heat recovery on the wastewater temperature in sewers
Water Research, 2014Raw wastewater contains considerable amounts of energy that can be recovered by means of a heat pump and a heat exchanger installed in the sewer. The technique is well established, and there are approximately 50 facilities in Switzerland, many of which have been successfully using this technique for years.

Spatial and temporal considerations in the performance of wastewater heat recovery systems
Journal of Cleaner Production, 2020Abstract In December 2018, wastewater was officially recognized by the European Union as a renewable source of energy, thus wastewater heat recovery can be included in efforts to reduce greenhouse gas emissions. Given the fact that wastewater treatment plants can generate enormous heat surpluses, this decision gives leeway to couple the wastewater ...

Energy and Buildings, 2011
There is a large potential in the heat losses from the wastewater leaving a building. We present a novel concept for recovering this heat. Instead of recovering it in a mixed state, the recovery immediately after use is evaluated. This allows the exploitation of the higher temperatures found at the points of warm water usage. By integrating a heat pump

Energy recovery from wastewater: Heat over organics
Water Research, 2019In dealing with wastewater, chemical energy has traditionally been perceived as the only source of recoverable energy in moving towards the carbon-neutral operation of wastewater treatment plants. Based on an estimation of practically recoverable energy embedded in municipal wastewater, however, the potential for thermal energy (90% recovery from ...

Heat recovery from wastewaters for household space heating
Journal of Environmental Science and Health . Part A: Environmental Science and Engineering, 1977The potential for using heat recovered from household wastewater for space heating is explored. A breakdown of the average household's daily production of 240 gallons of wastewater is analyzed to determine a recoverable heat potential of 50,000 Btu per day.

HEAT RECOVERY FROM MUNICIPAL WASTEWATER: EVALUATION AND PROPOSALS
Environmental Engineering and Management Journal, 2014Municipal wastewater, characterized by temperatures of 14-22°C in the inflow of Wastewater Treatment Plants and above 35-40°C in domestic outflows, represents a relevant thermal energy source. A feasibility study of the implementation of heat recovery from a specific sewer system should take into account several aspects: potential heat capacity ...

SWEET HEAT Modelling Wastewater Temperatures for Efficient Wastewater Heat Recovery
A measurement campaign of wastewater temperatures was carried out in a section of the Berlin wastewater network. These results were used to carry out a temperature simulation using the EPA SWMM-Fork SWMM-HEAT. It was shown that a good agreement between measurements and simulations is possible for predominantly residential areas, even if the network wasKoslowski, Johannes +5 more
