En beskrivande litteraturstudie
… Average temperatures today in Swedish district heating systems are for supply water 86 ° C and for return water 47 ° C. In the future temperature levels could decrease to current with temperatures down against 55 ° C supply temperature and 25-20 ° C return temperature. The …
This master thesis is developed based on the desire of the water and sewage department in the municipality of Karlskrona. The department, which vouches for the quality of produced drinking water and sewage cleaning, was in need of help dealing with risk analysis. The water and …
Water is vital for all life on earth. But it can also be dangerous, even fatal, if it is polluted water. 60 percent of child mortality can directly be deduced to dirty water. Not only developing countries are affected, even in the western world epidemics are breaking out by …
… is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with …
… company Immerse Global whose vision was to develop a new type of Atmospheric Water Generators, a machine that absorbs the moisture in the air and via a water system transforms it to pure drinking water. The project was partly financed by the Product Innovation Engineering …
En teknisk/ekonomisk utvärdering av reningsmetoder för metallhaltigt avloppsvatten
… methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna. Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been …
… An average house in Sweden uses 15 000 kWh for heating, 5000 kWh for tap water and 5000 kWh for electricity. These figures are based on each household using 14 000 kWh for heating, 5000 kWh for tap water and 8100 kWh for electricity. A wood furnace delivers the heat and the …
Optimering av beredningsparametrar för titandioxidbeläggning på polyestersubstrat ämnad för vattenrening
… effekten.In this bachelor essay work organic contaminants are removed from water using textiles, whose surface is coated with nanoparticles of titanium dioxide. When titanium dioxide is illuminated with UV radiation a photocatalytic reaction occurs, which in turn degrades …
En studie i sköljningsoptimering
… was concentrated on optimal wound irrigation pressures, scattering angle and water hit image in general and also a how to minimize the water scatter which is a negative byproduct in wound irrigation. This was conducted with interviews, literature studies and field studies …
Desinfektion med ånga
… The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam. A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in …
… that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program …
