Abstract
PURPOSE: To improve the dehydration treatment effect of sludge by measuring the viscosity or SEI (volume per SS unit weight when sludge is left standing for a prescribed time after it is controlled to the prescribed concn. of SS) of the sludge at prescribed concns., determining the index of sludge characteristic, and determining the cationic degree, addition rate or rate of treatment per unit time of a cationic org. polymer flocculant.
CONSTITUTION: The viscosity or SEI of the sludge at prescribed concns. is measured, and from this value, the index of sludge characteristic is determined. The index may be the measured value of the viscosity or SEI per se or may be the ratio of the measured value of the viscosity or SEI to the measured value of the concn. of SS. In accordance with this index, the cationic degree suited for sludge dehydration, addition rate or the rate of dehydration treatment per unit time of sludge of a cationic org. polymer flucculant is determined.
