On Demand Treatment of Wastewater Using 3D-Printed Membrane
This project will demonstrate on-demand separation of multicomponent and multiphase water-oil mixtures using 3D-printed membranes. It is focused on wastewater treatment that is critical to the chemical industry. Application and adoption of intensified process design and 3D-printed membranes offers the prospect of revolutionizing the multicomponent and multiphase water-oil separation. While conventional membranes have been utilized in oil-water separation for some time, demonstration of 3D-printed membranes with well-controlled local structure, which renders the membrane to have multi-selectivity, is still lacking to-date. Moreover, wastewater treatment often involves many steps and a more intensified process, which is enabled by a single multi-selectivity membrane, is highly desirable. The driving force for the proposed membrane is surface selectivity and topology rather than pressure and has been demonstrated in the laboratory. The present project aims to be a first-of-its-kind demonstration of the validity of the above-mentioned concept for the chemical industry.
