Abstract
Vacuum filtration is the most common method used for sludge dewatering. Filtering or dewatering was operated to reduce the moisture content of the sludge after anaerobic digestion treatment.
The main purpose of this study is to determine the effect of the operating conditions of anaerobic digestion system on specific resistance in sludge filtration. The anaerobic sludges used for the present study were produced from the conventional single stage system and the multiple-stage system. From the experimental results, presently obtained that it is possible to compare the advantage and disadvantage of the two different digestion systems.
In addition, the effectiveness of chemical conditioner on sludge filtration was also investigated. It is evident that the multiple-stage digested sludge is required less amount of conditioner dosage in mininizing its specific resistance.
