  • Profile

    My research efforts for the last fifteen years have been in the area of treatment of municipal wastewater to remove nitrogen typically present in the form of ammonia and organic-nitrogen. Nitrogen has been identified as the limiting nutrient in the Long Island Sound and the Upper East River. Our involvement has been to assist the NYC Department of Environmental Protection, (DEP), to identify, develop, and demonstrate technologies that can be implemented in the existing water pollution control plants, (WPCPs), to comply with the more stringent nitrogen discharge limits imposed by the NYS Department of Environmental Conservation. Our research encompasses bench scale studies conducted at City College, full-scale demonstrations of treatment processes at several WPCPs, computational fluid dynamic modeling of the final settling tanks, and assessment of microbial population dynamics in the biological wastewater treatment processes. Our research team includes research associates, graduate and undergraduate students.
