Hot brines used in traditional membrane distillation systems are highly corrosive, making the heat exchangers and other system elements expensive, and limiting water recovery (a). To improve this, UCR researchers developed a self-heating carbon nanotube-based membrane that only heats brine at the membrane surface (b), where the porous carbon nanotube layer acts as a Joule heater (c).
