Abstract: A three-dimensional Navier-Stokes code with pseudo-compressibility, an implicit formulation of finite difference, and a k – ε two-equation turbulence model has been developed for the Francis ...

Abstract: Five biofilm airlift suspension (BAS) reactors filled with ceramic materials as biocarriers were used to investigate the hydrodynamics, liquid mixing, and biofilm detachment kinetics in the BAS reactor. A mathematical model ...

Abstract: In this study, we describe the fractional convection operator for the first time and present its discrete form with second-order convergence. A numerical scheme for the fractional-convection–diffusion equation is also ...

Abstract: In this paper, accelerated tests are conducted on the bond performance of steel fiber–reinforced polymer composite bars (SFCBs) with sea sand concrete and the flexural performance of SFCB-reinforced sea sand concrete beams ...

Abstract: This paper presents a theoretical investigation on excess sludge production in membrane bioreactors for municipal wastewater treatment. Based on mass balances of sludge and substrate, a formula to predict the excess sludge ...

Abstract: Anaerobic and aerobic treatment of high-strength pharmaceutical wastewater was evaluated in this study. A batch test was performed to study the biodegradability of the wastewater, and the result indicated that a combination ...

Abstract: Coke plant wastewater produces severe pollution throughout China because coal is the main energy resource. The anoxic-oxic (A

Abstract: The anaerobic-anoxic-nitrification (A
