Research of the problems of heat recovery of sewerage flows in residential buildings

Abstract

Household activities of people and industrial technological processes generate a colossal amount of energy, which is often dumped into water bodies, sometimes without a proper cleaning and cooling process. Subsequently, pollution of various kinds of substances and suspended particles occurs, in parallel with uncontrolled thermal emissions, which leads to a serious disruption of the ecosystem of natural objects. Using the thermal potential of wastewater is, to some extent, a rational solution, both for improving the ecological situation and for some economic benefit. Since industrial effluents should be considered in relation to each, separately taken, particular case, due to the variability of the chemical composition, thermal potential and the possible degree of utilization, the issue of utilizing the heat of domestic wastewater deserves special attention. The plant variants offered on the market provide specialized equipment with already completed components, and the wide variety of assortments makes it somewhat difficult to find the most efficient scheme. In order to find a balanced solution between cost and performance, it becomes necessary to research each individual work component. Thanks to this, it is possible to find out which designs are most acceptable for specific initial parameters of the primary coolant, in particular, domestic wastewater.
