Abstract
Anaerobic digestion (AD) is a biochemical process in which organic matter is converted into biogas in a series of biochemical reactions. The development of high-rate anaerobic reactors (HRAR) led to the breakthrough of full-scale applications of AD for the treatment of industrial wastewater. HRARs, such as the upflow anaerobic sludge blanket (UASB) or the expanded granular sludge bed (EGSB) reactors are characterized by long solids retention times obtained by the gravitational separation of the solids from the liquid. Enhanced biomass retention is facilitated by the formation and growth of granular methanogenic biomass in EGSB and, most commonly also, in UASB reactors treating industrial wastewaters....
