At Isofoton, we are pursuing a solution to the issue of water: about 1.2 billion people throughout the world do not have access to protected water supplies. Even though 70% of the Earth's surface is covered in water, only 2.5% is fresh water, while the remaining 97.5% is salt water.
Thanks to reverse osmosis, we exploit salt water using the desalination process in all regions where there is a scarcity of fresh water; the reverse-osmosis method is very simple, efficient, and economically viable, which makes it the most developed technology of recent times. It consists of pumping water at high pressure through semi-permeable polyamide membranes after pretreatment with filtration, without introducing chemicals, thus reducing salinity until drinking water is achieved.
Isofoton has worked with the Instituto Tecnológico de Canarias (ITC - Canary Islands Institute of Technology) and VEOLIA Water Systems to develop a pilot plant powered exclusively by Photovoltaic Solar Power, using nothing more than a small battery so that everything functions correctly.
Three key points are worth highlighting:
