Produktion av dricksvatten och förnybar el i Bläsinge fiskehamn
The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well. This work includes inquiries of two solutions for extracting freshwater from the Baltic Sea, the ClearCrystals? technology and reverse osmosis.The analysis of the electric energy use shows that the fishing harbor has a need for electricity, which is 32900 kWh, using the chosen water purifying technology, which is reverse osmosis. The need for electric energy will be concentrated to the warm months; the most electricity intense processes are the refrigeration and the ice-making.To meet the wish of the fishing association, to reduce their cost for electric energy and at the same time get an environmentally friendly interface, the possibilities for alternative electric energy production has been investigated. The most relevant solution for the association has been small scale wind power, but the possibilities for solar cells are also an interesting solution. A wind turbine that will be able to produce the yearly amount of electric energy that the port needs, should have a rated power at around 20 kW and a tower height of at least 18 m.
