Outline of Final Research Achievements

Anammox coupling with nitrate reduction was studied under inorganic electron donors and under organic solid electron donors, using sludge acclimatized to have anammox and denitrification activities.
Hydrogen, in inorganic electron donors, was shown to be advantageous. Rice husk, in organic solid electron donors, was effective than rice straw or sawdust. However, wastewater treatment using sequencing batch reactor for anammox coupling with nitrate reduction added rice husk could not remove nitrogen effectively.
