Hybrid Surfaces to Enhance Oil-Water Separation

Membrane-based separation technologies are increasingly finding broad industrial applications such as remediating natural water sources and industrial or municipal wastewater, and desalination. Compared to hitherto separation processes, they are relatively energy-efficient and cost-effective. However, dissolved and suspended solids in the feed stream can foul membranes which remains a major challenge and hinders industrial adoption. In this research, a hybrid membrane surface will be developed with alternating hydrophobic and hydrophilic zones that can be utilized to separate and desalinate an oil and saline water mixture. Cerium oxide, which can be rendered either hydrophilic or hydrophobic by tuning surface chemistry will be used to manipulate membrane wettability. The expected outcomes of this project are a robust and functional membrane with anti-fouling properties that can selectively and efficiently separate water and oil. Given the robust chemistry of the cerium oxide ceramic, the membrane is also expected to maintain integrity under temperatures exceeding 90°C.
