Abstract

Microwave (MW) technique is a promising process for sludge conditioning, numerous papers has verified the beneficial effects on the microbial degradation and anaerobic digestion of municipal sewage sludge, but cannot be found study specialized on the investigation of MW process with different intensities for sewage sludge generated in food industry wastewater purification technologies. Our research was focused on obtaining optimum parameters of MW pre-ireatment for meal processing sewage sludge (MPSS) using solubility index (SLI) and the 5 days biodegradability index (BDIs) as control parameters. For the modeling and optimization response surface methodology (RSM) and multiple linear regressions (MLR) were applied, respectively. The investigated factors were the irradiated MW energy (IMWE) and the specific MW power level (MWPL). The results shown, that since the large-scale biodegradability enhancement, the MW pre-treatment is suitable for MPSS conditioning. The MW pre-treatmcnts could be advantageous in numerous process based on biological transformation, such as activated sludge recycling processes, composting and anaerobic digestion.
