RIVERSIDE, Calif. — Engineers at the University of California, Riverside have developed a new way to recover almost 100 percent of the water from highly concentrated salt solutions. The system will alleviate water shortages in arid regions and reduce concerns surrounding high salinity brine disposal, such as hydraulic fracturing waste. The research, which involves the development of a carbon nanotube-based heating element that will vastly improve the recovery of fresh water during membrane distillation processes,
