Application of upflow anaerobic sludge blanket (UASB) reactor for food waste and pome treatment with biogas production

The need for clean water is rising and anaerobic wastewater treatment can be used as a cost effective way out for biodegradation and energy production of organically polluted industrial waste streams. Indeed, the anaerobic digestion process can be applied to conduct various types of wastewaters in a...
