Microwave Drying Kinetics of Chromium-Rich Electroplating Sludge
نویسندگان
چکیده
Chromium-rich electroplating sludge (CRES) is a hazardous solid waste with high content of moisture requiring efficient drying before subsequent treatment. In this study, the microwave kinetics CRES were examined. The results showed that had good absorptivity, contributing to much shorter time and better performance compared conventional drying. comparison at 105 °C, 600 W for total removal was reduced by 98.5%. Compared load mass particle size, power played more important role in Based on analysis, process could be divided into three successive stages, which rates limited external diffusion (before 110 s), both chemical reaction (between s 160 (after respectively. Danish model found have best fit CRES.

Extraction and recovery of chromium from electroplating sludge.
This work reports a study of the extraction and recovery of chromium from the wastes (class I dangerous) generated by a galvanic manufacturer. Commercial HCl at room temperature was employed, and the conditions of the extraction process were optimized according to a sequential experimental design, which also included the acid concentration and contact time as variables. The best extraction cond...
متن کاملA pilot-scale microwave technology for sludge sanitization and drying
Large volumes of sludge are produced from onsite sanitation systems in densely populated areas (e.g. slums and emergency settlements) and wastewater treatment facilities that contain high amounts of pathogens. There is a need for technological options which can effectively treat the rapidly accumulating sludge under these conditions. This study explored a pilot-scale microwave (MW) based reacto...
متن کاملComparison of Drying Characteristic and Biodegradability of Dairy Sludge Using Microwave and Infrared Drying
In our work we focused on the investigation of two intensive drying methods, i.e. infrared (IR) and microwave (MW) drying, for dairy sludge. During the experiments the effects of IR and MW drying with different power intensities on drying characteristic and biodegradability were examined. Our results has revealed that MW drying was more advantageous for dairy sludge, because the drying time nee...
