- Abstract
- In this paper. we quantify the effect of heating pretreatment on the degree of solubilization of waste activated sludge. The pretreatment process was carried Out using a lab-scale industrial microwave unit (2450 MHz frequency). Response surface analysis was applied to determine the combination of output power (400-1600 W), target temperature (60-120 degrees C), and total solid concentration (1-3% total solid (TS)). The power, temperature, and TS concentration significantly affected the solubilization degree of sludge. Within the design boundaries, the conditions predicted to maximize the solubilization degree of 17.9% were determined to be 400 W, 102 degrees C, and 2.3% TS. (C) 2009 Elsevier Ltd.
