The dynamic adsorption of Pb(II) ions from aqueous solutions using a granulated activated carbon and an activated carbon cloth has been studied using fixed bed adsorption column. The breakthrough curves at different hydraulic loading rates (HLR), bed depth and feed concentration (Co) have been examined. The breakthrough time at any given concentration of the effluent decreases with increasing h...
the experimental studies of methane conversion to higher hydrocarbons and methanol using a dielectric barrier discharge (dbd) reactor are presented in this article. the process is carried out at ambient atmospheric pressure and temperature. the dbd reactor is stimulated by an alternative voltage of 50 hz and amplitude of max.23kv. the examination of the effect of voltage and flow rates on metha...

Biological nitrogen removal in an activated sludge process is obtained by two biological processes: nitrification and denitrification. Denitrifying bacteria need sufficient amounts of readily metabolized carbon. The objective of this paper is to develop an automatic control strategy for adjusting the external carbon flow rate so that the nitrate concentration in the last anoxic compartment is k...
modeling of stream flow–suspended sediment relationship is one of the most studied topics in hydrology due to itsessential application to water resources management. recently, artificial intelligence has gained much popularity owing toits application in calibrating the nonlinear relationships inherent in the stream flow–suspended sediment relationship. thisstudy made us of adaptive neuro-fuzzy ...
In this study, the modeling of hydrogen production process in microreactors by methanol-steam reforming reaction is investigated. The catalytic reaction of methanol-steam reforming producing hydrogen is simulated considering a 3D geometry for the microreactor. To calculate diffusion among species, mixture average correlations are compared to Stephan-Maxwell equations. The reactions occurring in...
Model-based control and monitoring such as feed-forward/feedback control, fault detection and isolation (FDI), and fault-tolerant control (FTC) techniques that utilize Lyapunov-based control laws are implemented on a high recovery reverse osmosis desalination plant model. A detailed mathematical model of a high recovery reverse osmosis plant is developed. This model incorporates the large spati...
A propeller-wash bead filter (PWBF) and a fluidized sand filter (FSF) on a 28 m recirculating system stocked with tilapia maintained favorablewater quality at five different feed rates, ranging from 0.9 to 4.5 kg feed per day. TAN removal rates ranged up to about 200 g TAN/m of media per day for each of the units. Peak rates of 244 g TAN/m of media per day were observed when the recirculating f...
