Christopher Bellona

Associate Professor, Civil and Environmental Engineering
Christopher BellonaMy teaching and research interests primarily revolve around technologies for water and wastewater treatment, water reuse, and remediation. Particularly, I strive to use fundamental concepts to understand the behavior of large treatment systems. A large percentage of my research has been focused on potable wastewater reuse and the removal of organic contaminants from water and wastewater using advanced treatment processes. Past research projects include modeling the removal of contaminants by high-pressure membrane systems, evaluating nanofiltration as a replacement for reverse osmosis in potable reuse systems, and elucidating the cause and effects of fouling in membrane systems. I have been involved in the fabrication and evaluation of various membrane systems including ceramic and polymeric microfiltration, nanofiltration, and reverse osmosis membranes. Current research interests include advanced oxidation processes, anaerobic membrane bioreactor systems for the treatment of mixed wastes and the recovery of valuable constituents from various waste streams.

My teaching interests mirror my research activities and courses taught include aquatic chemistry, chemodynamics, hazardous waste management, physico-chemical treatment processes, and senior design.  Due to my strong interest in process engineering, my overarching goal is to provide students with the knowledge required to effectively design and operate treatment systems.
