Abstract
The feasibility of employment of capillary suction time (CST) for characterizing the dewaterability of excess activated sludges was examined. The CST was shown as a good index for sludge filterability, if only the product of solid concentration and average specific resistance is of interest. On the other hand, the bound water content cannot be directly evaluated from the CST data.The feasibility of employment of capillary suction time (CST) for characterizing the dewaterability of excess activated sludges was examined.
