Everyone knows there’s a need for technologies to make fresh water safe for drinking. But Oasys Water has found the strongest demand for its technology comes from treating some of the nastiest water around, particularly wastewater associated with fossil fuels. On Tuesday, the Boston-based company said its forward-osmosis water purification system will be used at a coal power plant in China to remove the sulfur from polluted water. It’s the first of what could be hundreds of similar deals for Oasys in the coming years in China, where coal plant operators face regulations to treat water used to remove sulfur from coal plant gases, says Oasys CEO Jim Matheson.
