A Theoretical  and experimental investigation was conducted to study recovery of vanadium from spent catalyst via leaching process using sodium hydroxide to investigate the effect of process variables on vanadium recovery and study kinetic of recovered  was investigated by determining the controlling step.The effect of process variables (temperature, particle size,molarity of sodium hydroxide and leaching time) on the percentages of vanadium recovery were investigated and it was found that the percentage of vanadium recovery increased with:

The present study is to analyze and model concentration polarization in spiral wound brackish water membrane elements. The aim of the present work is to study the effect of different operating parameters on the reverse osmosis system which are feed flow rate, feed concentration, and feed temperature on permeate concentration and mass transfer coefficient for the brackish water system.

     In this study, a theoretical analysis of optimum bed thickness for realizing a high efficiency and reaction conversion of an electrochemical reactor has been made based on flow-through porous electrode (FTPE) configuration. Another configuration of porous electrode (flow-by) has been reviewed beside the considered one. The method that has been used is to find out a mathematical model to represent the optimum bed thickness by taking a look into previous works concerned and collecting all related information, data, and models.
