… intoconsideration the potential for growth of Legionella bacteria in hot water systems.The report's goal is to present a theoretical design of a low temperature secondary network for districtheating located in Lillehammer, Norway. The report is written in collaboration with the …
… the availability of methods and that are used in Sweden for establishing a water balance for a landfill. The identification work showed that the landfill consists mainly of household-, construction- and industrial waste, retted sludge from sewage treatment plants and soil, which …
… importance of irrigation scheduling in dry climate is shown, how it can save water and energy; how this method can improve crop yield by supplying the right amount of water at the right time. It is shown how irrigation scheduling and irri-gation technology together increase the …
… Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam …
… that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small …
