Simplified model for hydrogenotrophic denitrification in an unsaturated-flow pressurized reactor

摘要

A novel unsaturated-flow pressurized reactor (UFPR) for hydrogenotrophic denitrification was recently developed. The reactor is characterized by safe and economic operation since gas purging intrinsic to conventional H-2-based systems is not required and H-2 loss is limited only to the dissolved H-2 in the effluent. Additionally, high denitrification rates are achieved by high water recirculation over plastic carriers with high surface area.
