Abstract: A kinetic model (incorporating intrinsic Haldane kinetics) and an empirical model (incorporating apparent Haldane kinetics) for phenol degradation in upflow anaerobic sludge bed (UASB) reactors were used. UASB-reactor ...

Abstract: From the performance data of the upflow sludge bed (USB) reactors (with sufficient carbon), the rate-limiting step in denitrification is nitrate reduction. Biological denitrification in the USB reactors (superficial ...

Abstract: The resonator is stimulated by piezoelectric ceramics to produce oscillations with frequencies in the ultrasonic region for the ultrasonic motor application. The steady-state temperature rise due ...

Abstract: This study presents the optimal design for the resonator beam profile of a bimodal ultrasonic motor via finite element modeling and Taguchi experimental design method. General design goals of ...

Abstract: Laboratory-scale temperature-controlled reactors were used to generate experimental data of thermophilic composting of vegetable waste. By fitting in experimental data of thermophilic composting, the obtained empirical ...

Abstract: The performance of the conventional activated-sludge reactor (CASR) treating high-salinity, fish market wastewater (212–345 mg biochemical oxygen demand/L) can be enhanced by the addition of phototrophic bacteria (PTB). ...

Abstract: The unique architectural style of Western Hunan traditional dwellings must be protected, and their poor indoor thermal environment should also be improved. This investigation sought to determine the optimal passive ...

Abstract: Driven by both climate change and urbanization, extreme rainfall events are becoming more frequent and having an increasing impact on urban commuting. Using hourly rainfall data and “metro” origin–destination (OD) flow ...

Abstract: A mathematical model describing the transient hydraulic head distribution induced by constant-head pumping/injection at a partially penetrating well in a radial two-zone confined aquifer is a mixed-type boundary value ...
