AquaFresco – Reinventing laundry

AquaFresco provides the state-of-the-art filtration technology which regenerates 95% of laundry wastewater. Three MIT grad students have invented a washing-machine filter that cleans wastewater and reuses it over and over again. “Washing machines are one of the major sources of detergent pollution in rivers,” Huang says. “Current laundry technology is not sustainable. A regular washer discards the water right into the drain after one usage, but less than 1 percent is the actual waste component.”...

New, inexpensive way to clean water from oil sands production

Researchers have developed a process to remove contaminants from oil sands wastewater using only sunlight and nanoparticles that is more effective and inexpensive than conventional treatment methods. Frank Gu, a professor in the Faculty of Engineering at the University of Waterloo and Canada Research Chair in Nanotechnology Engineering, is the senior researcher on the team that was the first to find that photocatalysis , a chemical reaction that involves the absorption of light by nanoparticles ...
