Wastewater is used on one hand as a source of energy for heating and, on the other, for cooling. The use of wastewater energy can further be subdivided into three categories depending on where the energy is extracted: In-house energy recuperation, energy recovery from raw wastewater (sewers), energy recovery from cleansed wastewater by the sewage treatment plant.
This paper describes a decentralized wastewater treatment system in rural households using heat extracted from wastewater using heat pumps.
Mathematical model of heat pumps and AB reactor plant are made in software package MathCAD. Moreover, conceptual solution and a 3D model of this plant are made in the software package CATIA V5R20. In the end, techno-economic analysis of such a solution is done.
