The bacterial population in an H 2 -dependent denitrification system was studied. The laboratory set-up was designed for the treatment of potable water and consisted of an electrochemical cell, where the water to be treated was enriched with H 2 prior to entering a bioreactor. Bioreactors (columns packed with granulated active carbon) were inoculated with denitrifying bacterial strains...
An autotrophic biological process was developed for the treatment of nitrate-contaminated drinking water. The system comprised of two steps: the water to be treated was first enriched with hydrogen (energy source) in the cathodic chamber of an electrochemical cell, and then denitrified in the bioreactor. The bioreactor was a packed bed of granulated activated carbon, and the water flow was directed...
