Nowadays, the problem of water shortage in some areas has become increasingly prominent. In the process of studying water reuse, desalination technology research work is also in full Swing. The traditional membrane distillation system has some drawbacks, but also expensive parts, not suitable for large-scale promotion. Today, the University of California team developed a carbon nanotube heating control that not only improves freshwater recovery in membrane distillation but also saves energy. Desalination technology breakthrough breakthrough Water recovery rate approaching 100% It is reported that hot salt water used in traditional membrane distillation systems is highly corrosive, making the heat exchangers and other system components expensive and limiting the recovery of water. Today, scientists have developed a device that is not only cheap but more efficient than the previous device. One American engineer found a way. This method makes it possible to extract nearly 100% of the water from the brine. This innovation not only relieves the pressure of water scarcity in water-scarce regions, but it also reduces the emissions that contain highly mineral wastewaters, such as those used in fracking. The water crisis in today's world is getting worse. Under such circumstances, seawater desalination has become a good choice and the project has been implemented in Israel for several years. Of course, this process can still be significantly improved. The team from the University of California, Riverside, showed us the technology. The team developed a carbon nanotube heating control that greatly improves the recovery of fresh water from the membrane distillation process. An assistant professor at the team showed that the previous recovery was at a very low value. Ideally, the thermal desalination process will recycle all of the water in the brine, leaving only a small amount of crystalline salt that can either be used or discarded. Unfortunately, existing membrane distillation processes rely on hot brine Of the water flowing through the membrane, during which time the water recovery across the membrane is limited to 6%. " Most desalination equipment uses reverse osmosis, but the greater the salt content, the lower the efficiency. Therefore, when dealing with brine, reverse osmosis efficiency is very low. However, such salts are not naturally produced, they are often produced wastewater and must be disposed of so as not to pollute the environment. Researchers are not sure how they can ensure that all water can be desalinated, but at least reduce the amount of heat required during treatment to save energy. Another interesting result of this study is that hot brine is highly corrosive. To develop this device, they must also ensure that components can withstand concentrated brine and run properly for long periods of time. Thus, they determine the threshold frequency at which electrochemical oxidation of nanotubes can be prevented.
