| Outline of Final Research Achievements |
A biological filtration (BF) system developed by our group for simultaneous removal of Fe and As in a potable water treatment system for groundwater in Hanam Province. In order to remove residual ammonium in the BF-treated water, one-stage partial nitritation - anammox reactor was used at the Hanam site. Ammonium, nitrite and nitrate concentrations in the final effluent satisfied the Vietnamese standard for domestic water. Analysis of 16S rRNA genes revealed that tndigenous anammox bacteria proliferated on the biological filter for removal of Fe and As, could have worked as a seed for the anammox reactor, and helped stabilize its nitrogen removal.
