Biological solubilization and mineralization process was proposed for food wastes. In the process food wastes are mixed with rice hull as biological support medium under wet condition and are solubilized or mineralized. The purposes of the study are to operate the biological solubilization and mineralization process without accumulation of food wastes and to increase mineralization rate for the reduction of organic loading to the sewerage system. Biological solubilization and mineralization process was operated without the accumulation of food waste by aeration in the circulation tank. The process can reduce organic loading to the sewage system to half by aeration in the circulation tank and 80 % by installing biofilm into the circulation tank. The process combined with biofilter would not require further treatment of effluent.
