Abstract
The drying of wastewater sludge with or without an artificial crack was monitored using an electronic balance and an X-ray micro-computerized tomography scanner (micro-CT). The drying rates for sludge cake without a crack was 50-60% of pure water test. With an artificial crack of triangular cross section whose orientation was parallel to (P-type) or normal to (N-type) the air flow, their peak drying rates would be higher than that of cake without a crack. Also, the drying rate of sludge cake with P-type crack was higher than that with N-type crack, being attributable to the additional surface yielded by artificial crack. Using the total surface area as a basis, the effective drying fluxes from sludge cake were noted to close to the water drying test. Copyright © 2005 Taylor & Francis, Inc.
