Micropollution in natural waters such as rivers and groundwater aquifers is a widespread problem that prevents these potentially potable sources from being used as drinking water. At the same time, utilization of biomass-based raw materials (e.g., bacteria, algae, and cellulose) for the production of high value chemicals such as proteins, pharmaceuticals, and biofuels is gaining an increasing interest. Traditional membrane filtration faces major challenges such as polymer aging, membrane fouling, and high costs. Thus, developing sustainable and efficient membrane filtration technologies is not only critical for safe drinking water supply but also important for many chemical processing or refineries such as biomass separation and biofuel production. This project is to develop an innovative and multifunctional reactive electrochemical membrane (REM) that exhibit great antifouling characteristics and strong surface reactivity.  Our research focuses on four aspects: (1) development and testing of a suite of tailored monolithic or nanofibrous REMs in biomass recovery; (2) evaluation of biomass separation efficiency, permeate water treatment, and anti-fouling properties using algae as model organisms; (3) experimental and modeling assessment of membrane fouling and regeneration kinetics and mechanisms; and (4) Ti4O7 reactive electrochemical membrane filtration for recalcitrant pollutants removal and microbial disinfection. The results not only provided fundamental guidelines as to the rational design of REMs with controlled and efficient performance, flexible structure, and durability of operation for algal recovery, but also leads to an avenue for the development of a new generation of reactive membranes that can be applied in other disciplines in addition to algal separation (e.g., food processing, drinking water treatment, and biomolecule purification in pharmaceutical industries).
