Abstract

When incineration method is utilized as a disposal process of sludge, the treatment generally consists of thickening, dewatering and incineration, implying that sludge dewaterability has a colose relationship with operating condition of a thickener. Dewatering factors should be, therefore investigated for achieving effective sludge treatment. No research on this has been performed in Korea. This study has focused on the evaluation on the effects of thickener operating variables on sludge dewatering, including sludge feed types and retention time. Mixing ratio of the first and the second sludge and operation time were varied in order to observe the change of dewaterability and optimum input of chemical conditioner.
