Review of Upflow Anaerobic Sludge Blanket Reactor ...
Upflow anaerobic sludge blanket (UASB) reactor is a widely used anaerobic treatment of wastewater that has numerous benefits over its alternatives, including aerobic wastewater treatments (Lettinga et al. 1980; Christensen et al. 1984; Khan et al. 2011) and other anaerobic treatments (Hamdi 1996; Rajeshwari et al. 2000; Rajakumar et al. 2011; Ayaz et al. 2012). Since the amendment of the Renewable Energy Sources Act in Germany (Erneuerbare Energien Gesetz) the utilization of energy crops for biogas production has become more cost‐effective. The treatment of animal waste slurry and energy crops in co‐digestion is a proven technology and recently interest has grown in the potential of using anaerobic processes [ 1 , 2 ].
