Large-scale anaerobic/aerobic treatment of complex industrial wastewater using immobilized biomass in fluidized bed and air-lift suspension reactors

Results are presented on pilot and full-scale pretreatment of industrial wastewater in an anaerobic 2-stage fluidized bed reactor for CH 4 -production and laboratory and pilot scale post-treatment of the anaerobic effluent, which contains NH 4 + and HS − in an aerobic air-lift suspension reactor for the production of NO 3 − and SO 4 2−
