SURFACE CONFIGURATION AND MOISTURE TRANSFERENCE DURING SEWAGE SLUDGE DRYING
The drying mechanism is important to the drying technology of sewage sludge.Using dynamic electronic balance and image acquisition technique, the paper studies the change of surface configuration and characteristics of moisture transference for three kinds of sewage sludge during drying.In the meantime,the paper also analyses the influence of sludge shape on moisture transference and the change of sludge apparent volume and porosity in the course of drying.
