Clean Water Production Congress

Questions to ask are abundant in number. What is the cost? What about the problem of the brine. Which method: direct heating or reverse osmosis with the sun as power provider, or the Memstill technology?

Where this was too expensive with the traditional methods, there is now a solution with the help of a little bit of sun. Concentrated solar power can be the answer. A lot of problems need to be solved, a lot of questions are still unanswered, but there are possibilities.

This is what this symposium is about: looking at the realistic, concrete possibilities of fresh water production for the arid areas at an economical acceptable prize.

Prompted by the water crisis, the alternative solutions in providing clean and fresh water for human utilization and others purposes must be concerned. Since sustainability of the ground water supply as a primary source of clean water is decreasing day to day, for the reason that consumption of fresh water has raises and the water scarcity in the past decades. Desalination process is the one solution in order to increase the stock of clean water, and in optimizing the sea function for human life combined with the solar energy, which is powerful to gain the electricity power as well. However, a large –scale desalination process commonly uses giant amount of energy consumption and need enormous expenses, especially in infrastructures, compared to the use of the fresh water directly from river or groundwater or another surface water sources (lake, pond,etc). Another alternative, which is not requiring a huge cost and eco-friendly, should be considered. Some studies/ research has been conducted, that by combining the solar power and plants, would be an option to a low cost desalination process (phytotechnology for desalination, Where the solar power works for evaporation and Phytopower (plants) works for evapotranspiration process. (Sarwoko Mangkoedihardjo). Thus, especially is the most powerful for the tropical area, whereas the sun power is stands out for almost 12 hours a day in a whole year. For countries those have no large forest region, a wetland constructive area must be provided as a solution. Kadek Ayu Susiani Dewi-Indonesia - 09/10/2009 - 07:47
