 Voltaea is all about water purification. Water purification is a process in which salt is removed from water, for example from sea water, from tap water or from surface water. Water desalination is widely applied worldwide. It's used to produce water for agriculture, for industry and it involves the use of large quantities of energy and large quantities of chemicals. Voltaea's technology, which is called capacitive deionization, is unique in a sense that it uses very little chemicals and also produces very little waste water. When we started Voltaea in 2006, the technology was at a prototype stage. It was functional in the lab, but it was not yet suitable for commercial application. We focused our R&D mainly on the development of new materials to make them better but also more cost effective. And also on the testing of new applications to see and to prove that capacitive deionization gives a benefit to our customers. Capacitive deionization, or CAPDI in short, is a unique technology. Unlike other water desalination technologies, CAPDI is not a filter. Water actually flows freely through the module and then it passes a carbon electrode that's like this type of material, a very thin layer. And we apply a small voltage over those electrodes and as a result of that the salt that was in the water is absorbed on the electrodes. Desalination processes produce next to a purified stream, also a wastewater stream. For a conventional desalination process, we produce about as much wastewater as we produce desalinated water. One of the key benefits of capacitive deionization is that the amount of wastewater is significantly reduced by a factor of 3. Desalination processes use a lot of energy. One of the big advantages of capacitive deionization is that the amount of energy used to purify the water is very low. For example, one of the modules that we see here uses about the same amount of energy as one light bulb and that is much lower than with conventional processes. Traditional desalination processes have a huge environmental impact because of the large amounts of chemicals that are being used in these processes. On the contrast, CAPDI hardly needs any chemicals, so we don't need it. One of the applications we developed in collaboration with Spinter is the use of this technology for households to remove water harness and to condition the water. Our technology is ideally suitable for this application because we use no chemicals and produce very little waste. One of the focus applications for CAPDI technology is the treatment of water for cooling towers. Cooling towers are widely used, both in industry but also for example in large hospitals on the roof to cool the air conditions. Cooling towers use large amounts of water but also large amounts of chemicals. And by application of CAPDI technology, we can significantly reduce these amounts. We can reduce the wastewater stream of a typical cooling tower by 60% and we can reduce the chemical use by about a factor of 2. This has a huge environmental impact and a huge environmental benefit. We are excited and also very honoured that Voltea has been selected by the World Economic Forum as one of the technology pioneers of 2013. And we are also convinced that this will help us to introduce technology in many new applications and to reduce the environmental impact of water desalination worldwide.
