SEWAGE WATER HEAT RECOVERY: A PROPOSED STUDY AS AN APPLICATION OF ENERGY SAVING IN IRAQ

Abstract

An Innovative technology is used to recover some of the thermal energy of wastewater released by washing section in a restaurant as one of the energy saving applications to reduce electrical energy consumption for heating, as well as saving money. This research suggests using heat exchanger to recover heat from the sewage hot water (about 45 oC) to reheat the dining room for a proposed restaurant, and this will supply up to 8 Tons of heating load and will reduce the electrical energy that used to heat the place up to 44%. This technology within the system routes the passive energy conservation and considers another step on the way of sustainability.
