Analysis of waste heat recovery in a water treatment plant and the use of this heat in a commercial building

Abstract

Effective energy use plays a crucial role in the conservation of energy sources. The recovery of waste energy is one of the available energy saving potentials and can be the possibility of ensuring the energy needs of commercial buildings. To date, research on heat recovery from wastewater treatment has focused mainly on the heat potential of wastewater evaluation and technologies to apply this energy. This work examines the possibilities of wastewater heat recovery in the Vilnius wastewater treatment plant and assesses whether the thermal energy demand of the commercial building can be ensured by using the heat of the treated wastewater in a heat pump.
