“…The moisture content of the sewage sludge was decreased by 96 % in the present study. Menendez [15] reported about 92 % reduction in volume of sewage sludge after drying in MW compared to 89 % by conventional drying. Significant reduction in sewage sludge volume might bring economic benefit for its further processing.…”

Abstract-The purpose of this study was to investigate the effect of Microwave (MW) power levels (480 to 1080 W) and sample mass (90 to 150 g) on the drying characteristics of the sewage sludge. The drying tests were carried out using a modified domestic microwave unit with a process control system. The results showed that drying rate was directly proportional to the MW power, but inversely proportional to the sample mass. The desired temperature could be achieved in short period of time at higher power level. MW drying showed a significant increase (from 5.65 MJ/kg to 18.75 MJ/kg) in calorific value of sewage sludge.

“…In fact, a variety of processes involving microwaves have already been investigated. These have focused mainly on the pretreatment, including enhancement of anaerobic digestion Climent et al, 2007), desaturation (Wojciechowska, 2005), cell destruction (Hong et al, 2004) and solubilization of organic solids (Eskicioglu et al, 2006), but also on the vitrification of the solid residue using microwave heating for the purpose of decreasing the leaching of heavy metals (Menéndez et al, 2005). Various patent applications describing procedures or apparatus for carrying out the drying and/or pyrolysis of waste materials, including sewage sludge, have also been presented during the last 20 years (Sullivan III, 1986;Marks & Fluchel, 1991).…”

“…Consequently, the kinetic energy causes friction between these molecules leading to heating with heat transfer direction coming out from the centre of biomass material towards its surface. In addition, microwave heating is easy to control: it can be operated and terminated quickly, and the safety and automation of the heating is high (Haque, 1999;Menéndez et al, 2002;2005;Robinson et al, 2010). One of the most fundamental properties of microwave energy application in the thermal degradation of biomass is being material-selective heating, which results in different microwave energy absorption for different biomass or biomass dielectric properties (Menéndez et al, 2010;Omar et al, 2010).…”
