A Novel Membrane Process for Autotrophic Denitrification

Nitrate is one of the most common groundwater contaminants in the United States and elsewhere. This project investigated the feasibility of a new process for the biological denitrification of wastewater. Current biological denitrification processes use heterotrophic bacteria. However, these processes are expensive and result in production of more sludge. This study examined the possibility of a new form of autotrophic denitrification that uses a hollow fiber membrane to supply hydrogen gas to autotrophic bacteria. Using this process could make autotrophic denitrification more cost-effective than the currently used heterotrophic denitrification. Published by WERF. 76 pages. Soft cover.
