Abstract: Lo\v production of (stabilized) excess sludge.Low nutrient rcqui rcrnents.No energy rcquirclncnts for ucration. Production of methane.'{'he process cun frequently handle high space loads.Anaerobic sludge Ce:ln be preserved.unfed.for many nlonths without any serious deterioration.ValuClblc compounds like ammonia arc conserved.which in specific C<lses nlight represent un important benefit (i.e. if irrigation C~ln be applied).Anaerobic bacteria (particularly the rncthanogcns) are very susceptible to inhibition by a large number (If compounds.The startftup of the process is sill'\' if an .adaptedseed sludge is not nvailahlc.AJl<lcrobic trcatment norn1C.lllydenlands an adequate post-trcalJllcnt for the rcnloval or rcn1c.tiningBOD.anl monin and rnalodorous conlpounds.Little practic'll experience exists us yet 1 although the situation is rapidly changing in this respect.Unlike aerobic processes, the loading rate of the process generally is not limited by the supply of any required reagent/ingredient.The more sludge that can be retained, the higher the loading rates that can be applied, provided that sufficient contact between the sludge and the waste water can be maintained.The high retention of active sludge in the modern high-rate A WWT processes basically depends on;......
