Sludge Dewatering 2009

Final TM Evaluation of Dewatering Alternatives

Sludge conditioning with polymers is required to prevent floc shear and to improve centrate quality and solids capture. Concurrent solid bowl centrifugation has been shown to work better than countercurrent dewatering because the less turbulent inlet conditions reduce floc shear and a larger retention time for the solids is provided.
