Research Description

Dr. Call's research focuses on water and wastewater treatment technologies. He has expertise in both biological and electrochemical principles. Examples of current research interests include: 1) removal of emerging drinking water contaminants, including per- and polyfluoroalkyl substances (PFAS), using electrically-driven separation processes, 2) investigating microbial interactions with pyrogenic carbonaceous materials (e.g., activated carbon, biochar) to enable aqueous contaminant transformations (i.e., biological activated carbon) and energy recovery from wastewater (i.e., anaerobic digestion), 3) desalination of brackish water using capacitive deionization (CDI), 4) phosphate recovery from wastewater using nano-based sorbents, and 5) conversion of nitrogen gas into ammonium using microbial electrochemical technologies.
