Biological treatment of bioethanol producing wastewater

Bioethanol is renewable energy produced from agricultural feedstock and thus bioethanol has been attracting attention as an alternative fuel for gasoline. However, bioethanol produces massive amount of waste/wastewater during the production process. These waste/wastewater are fermentation waste, distillery waste and … Continue reading

Sulfur denitrification using sulfur compounds generated from biological desulfurization of biogas for industrial wastewater treatment

Anaerobic treatment of industrial wastewater produces not only useful methane but also highly toxic hydrogen sulfide gas. Especially for the wastewater containing high concentration sulfate, such as wastewater from molasses, natural rubber, and brewery, high concentration of hydrogen sulfide is … Continue reading

Elucidate an anaerobic sulfur oxidizing reaction in UASB reactor and utilization for sewage treatment system in low temperature condition

Our laboratory has been developing a sewage treatment system with UASB reactor for warm climate (average temperature: 15℃〜20℃). However, the performance of usual UASB such as organic matter removal decreases in winter because the decline of activities of methanogenic archaea … Continue reading
