Abstract:

Bench-scale tests and a pilot-scale experimental system were used to study the performance of a vacuum deaeration treatment method. The objective of this study was to improve the sedimentation and thickening of the transported sewage sludge that is extremely difficult to sediment. The raw sludge used in the tests was that collected from various sewage treatment plants in Nagoya City Japan. Results of continuous pilot plant tests carried out during each of the four seasons indicated that treating intensely putrefied anaerobic sludge by vacuum deaeration was effective for increasing the thickening of sludge, improving SS recovery, significantly decreasing the generation of odor elements in the sludge, as well as improving sludge dewaterability.
