Speciation of copper in the incineration waste heat boiler (HB) and the down stream electrostatic precipitator (EP) fly ashes during the flue gas cooling down (1123-->473 K) has been studied by X-ray absorption near edge structural (XANES) spectroscopy in the present work. Copper species such as Cu(OH)(2) (59-67%), CuCl(2) (5-12%), CuO (24-26%), and a small amount of CuS (3-4%) in fly ashes wer...

This work proposes a scheme for completely treating heavy metal laboratory waste liquid. Ten common heavy metals and various anions were dopted to synthesize the simulated laboratory waste liquid. Experimental results demonstrated that although conventional ferrite process (FP) ould not be used to treat the simulated waste liquid completely, the enhanced FP, i.e., the extended reaction ferrite ...

Municipal solid waste incineration fly ash is generated in a significant amount; it is classified as hazardous waste in Taiwan. In order to reduce the volume of treated fly ash, a sintering technology can be considered. However, a traditional sintering consumes too much energy because of the limit of heat transfer. Hence, a microwave process which can provide quick, uniform, and selective heati...

Eddie Schwalb2 and Llu s Vila3 Abstract. We aim at developing a logic-based representation language which supports an explicit representation of time and temporal constraints such as \the task t takes from 3 to 4 hours", \the resource r is available from 8:00 to 11:00 and from 13:00 to 14:00" and \task ti cannot overlap task tj". In this paper we discuss the issues to address and we propose TCL...

Bricks manufactured from dried sludge collected from an industrial wastewater treatment plant were investigated. Results of tests indicated that the sludge proportion and the firing temperature were the two key factors determining the brick quality. Increasing the sludge content results in a decrease of brick shrinkage, water absorption, and compressive strength. Results also showed that the br...
