Abstract
This work evaluates filtration followed by consolidation characteristics of sodium chloride containing activated sludge. Experimental results indicate that contact time and salinity level affect the dewatering efficiency. Considering the consolidation stage, a critical salinity level (around 1-2% (w/w)) is observed at which the contribution of secondary consolidation stage reaches its minimum. Meanwhile the creeping among constituent aggregates becomes much easier than in the original sludge. In addition, double-layer compression/hydrophobic interactions and ion exchange partially account for the experimental results.
