The application of biological processes for the treatment of water, wastewater, and hazardous waste.
Raymond Hozalski's research has a strong focus on biological processes for the treatment of water, wastewater, and hazardous waste. He is especially interested in biological processes involving bacteria immobilized on a solid surface in what are called biofilms. The main goals of Hozalski's biofilms research program are to enhance understanding of the structure and function of biofilms, to develop or improve treatment processes that utilize biofilms, and to develop strategies for controlling biofilm growth on surfaces when biofilms are not desired.
Current biofilms-related research projects being conducted by Hozalski include the characterization of haloacetic acid-degrading bacterial isolates obtained from drinking water distribution systems and investigation of the mechanical properties (e.g., strength, elastic modulus) of biofilms. Hozalski also recently collaborated with fellow BTI researchers Daniel Bond and Tim LaPara on a project concerning the use of microbial fuel cells for wastewater treatment.
