Effect of recirculation rate on anaerobic treatment of fleshing using UASB reactor with recovery of energy
This study presents performance of upflow anaerobic sludge blanket (UASB) reactor in treating liquefied fleshings (LFs) with tannery wastewater (TWW) using liquefaction reactor (LR). With increase in recirculation rate, methane production increased in LR than in UASB reactor due to methanogenic bacteria in LR. UASB reactor with continuous feeding of LFs and TWW resulted with cumulative methane in UASB reactor (128 1) and LR (145 1).
This paper deals with the broad-band modeling of a realistic power converter shield used in an electric vehicle. To validate such a model, comparisons between computation and measurements are required. As it is not practical to characterize experimentally the true radiation of a power converter through its enclosure, a reciprocal approach has been defined in which the enclosure is illuminated by a plane wave (receiving configuration). The associated experimental setup has been carefully defined and tested. At low frequency, the model is based on radiation through apertures in a simple cavity. At higher frequency, the Aseris-BE code, which is based on the boundary integral equations technique, has been used for computation. An optimal and realistic mesh of the enclosure suitable for the Aseris-BE code has been built by making numerous comparisons between computation and measurements, which have shown how to improve the mesh.
