Usama Zaher brings experience in wastewater engineering, bioprocess modeling and environmental sustainability assessment gained from working with research and engineering teams on diverse projects in the U.S., Europe, and the Middle East. His expertise in process modeling optimizes water quality solutions to meet environmental regulations and sustainability measures of waste and wastewater treatment services in the domestic, industrial and farming sectors. Usama is an expert in anaerobic digestion (AD) modeling, monitoring and control. His AD expertise involves contributing to the optimization of biogas plants and pre-treatment of industrial wastewater and farming wastes to recover resources and biogas for energy generation and to improve biodegradation of toxic organics. In the area of environmental sustainability, he implements multiscale and life cycle assessment mathematical and statistical modeling tools to simulate integrated environments, to analyze uncertainty, and to estimate ecological impacts and risks to support environmental technology selection and remedial decisions. He currently supports a team of modelers working on the environmental restoration efforts at the U.S. Department of Energy’s Hanford Site, where his responsibilities include modeling the site-wide inventory for composite risk analysis and evaluation of waste isolation and ground water remedial actions.
