industries in developing countries add new production lines producing altogether different waste stream. this newer waste invariably finds its way to existing anaerobic treatment system causing gradual/sudden change in feed substrates affecting its steady performances. this study investigates steady response of anaerobic reactors subjected to sudden change in feed substrate types, assesses its ...

We investigated rice husk as the sole carbon source as well as biofilm carrier in the biological denitrification of wastewater in up-flow laboratory reactors. Fast startup of the reactor and high nitrate removal efficiency was observed. The highest denitrification rate (about 0.096kg/m·d) was achieved when flow rate and nitrate concentration were 41.4L/d and 25.0mg/L, respectively. Flow rate an...

Breed-and-burn Molten Salt Reactors are an interesting option of reactor design that allow high fuel utilization while operating on open cycle. Such reactors usually require specialized codes in order to model its cycle and the flowing unmoderated core. In this work, we propose a perform preliminary analysis homogeneous chloride salt single-fluid design. The is analyzed using EQL0D tool start-u...

Biofouling impedes the performance of anaerobic membrane bioreactors (AnMBR). Two reactors, one as an up-flow attachment-growth AnMBR (UA-AnMBR) configuration, and other, a continuously stirred (CS-AnMBR) were evaluated for differences in fouling rate. TMP increment UA-AnMBR was slower than CS-AnMBR, although both reactors had similar COD removal efficiency (ca. > 96%). Slower rate related to l...

In order for underwater vehicles to fully realize the potential of utilizing oscillating foils as propulsion mechanisms, it is necessary for the control scheme to be aware of the state of the water environment, especially the vorticity in the water. In this paper, we investigate the problem of estimating the hydrodynamic potentials based on pressure measurement on a submerged body. A relationsh...
