| Research Abstract |
Anaerobic digestion process has been utilized for aerobic sludge reduction and stabilization in wastewater treatment plants in Europe, United States and Japan, for which knowledge on inorganic dissolution/precipitation has not been enough to simulate or control the situations such as the mechanical failure caused by unexpected solid precipitation and the phosphorous adsorption onto solid phase. This research project has developed the inorganic dissolution/precipitation model that predicted the aqueous/solid compositions of anaerobic digestion liquor, and also proposed an inhibitory measure against the unwanted solid precipitation in wastewater treatment plants.
