Heat from the Domestic and Industrial Wastwater

Stojan Gasharov

Abstract

More than 40% of the energy produced in the world is utilized by the building sector mainly for heating of buildings and water. Different methods are used for the reduction of this energy new thermo-isolating materials in the new building process, treating of the already existing buildings with thermo-isolating coverings, new aluminum and PVC frames for the windows, application of different solar equipments. At the same time the energy necessary for the heating of water for domestic usage increases permanently. Besides, the need for hot water is constant - every day, all year. Here the possibilities for saving energy are more limited limitation of the quantities of consumed hot water (but the statistics show just the opposite tendency), or recycling of the remaining heat that is contained in the sewerage hot water, domestic and industrial. This solution is possible and technologically feasible through the usage of thermo-exchanging devices and thermo-pumps, and a process in which only the heat / thermal energy / of the sewerage water is accumulated, and then returned to the equipments for heating water. The heating module could be repaid for a period of 3.5 4 years as a result of the savings of thermal energy, which is economically very advantageous. And last but not least, the process has favorable ecological effect, following the worlds latest tendencies.
