The Transition Stage in the Start-up of an Anaerobic Sludge Digester
The start up 
 dynamics of a one-million and two-hundred-thousand liter anaerobic digester of municipal waste treatment sludge was studied. In the digester, mixing was accomplished by circulation of the produced biogas at a rate of 0.13 m3 per hour of the digester volume per hour. During the nine-month study, no serious phenomena of foaming, getting sour, temperature fall, etc. were observe...

متن کاملCFD simulation of anaerobic digester with variable sewage sludge rheology.
A computational fluid dynamics (CFD) model that evaluates mechanical mixing in a full-scale anaerobic digester was developed to investigate the influence of sewage sludge rheology on the steady-state digester performance. Mechanical mixing is provided through an impeller located in a draft tube. Use is made of the Multiple Reference Frame model to incorporate the rotating impeller. The non-Newt...
متن کاملSludge transfer point of a UASB-digester system: key to efficient low temperature anaerobic sewage treatment
The up flow anaerobic sludge bed (UASB)-digester system is one promising low temperature anaerobic process for sewage treatment. In this study, the effects of height of UASB sludge transfer (HUST) on performance of a UASB-digester system treating sewage at 15°C were studied. The studied HUSTs were 27, 47 and 67 cm in the UASB sludge bed of 70 cm, from which sludge was transferred to the digeste...
