  • What is psychrophilic anaerobic treatment?
  • Psychrophilic anaerobic treatment is an attractive option for wastewaters that are discharged at moderate to low temperature. The expanded granular sludge bed (EGSB) reactor has been shown to be a feasible system for anaerobic treatment of mainly soluble and pre-acidified wastewater at temperatures of 5–10°C.
  • Can psychrophilic anwt be used in industrial wastewater?
  • Especially when using staged EGSB-reactors, psychrophilic AnWT is feasible and is now open for full scale applications to low strength, mainly or partially acidified wastewater, including various types of industrial wastewater and pre-settled domestic sewage. Also temperatures below 10°C can probably be applied.
  • Can psychrophilic conditions affect non-acidified wastewater?
  • When imposing non-acidified wastewater to the treatment using a methanogenic reactor under psychrophilic conditions, a serious problem is the formation of a layer of acidifying sludge around the granules present in the EGSB or UASB reactors.
  • What is anaerobic sewage treatment?
  • Anaerobic sewage treatment is a real challenge in moderate climates because sewage belongs to the ‘complex’ wastewater category and contains a high fraction of particulate COD.
