FEASIBILITY STUDY OF HEAT RECOVERY FORM TREATED WASTEWATER IN WASTEWATER TREATMENT PLANT AND USE IT IN NEARBY OBJECT

Nowadays, the supply of energy from renewable energy sources is important in the energy sector of every country, so it is necessary to pay attention to alternative sources with thermal potential. The aim of this article is to perform an analysis of the possibilities of using heat from the wastewater treated at the Vilnius wastewater treatment plant. The work determines the temperature and flow fluctuations of the wastewater treated in the treatment plant, the theoretical heat potential. The heat demand of a commercial building is calculated. Based on these data, the parameters of a heat pump using treated wastewater are determined and a system model is created in a energy simulation software and the heat supply of the building is estimated.
