“…Response surface methodology (RSM) is an important subject in the statistical design of the experiments. It was successfully applied in several wastewater treatment systems, such as adsorption [23,24], chlorine disinfection [25] , electrocoagulation [26] , Fenton-related process [27] , and electrochemical oxidation [28]. RSM was widely used as an optimization system in other processes such as biofluid separation [29,30].…”

A rotating tubular packed bed electrochemical reactor was used for the electrochemical removal of cadmium (Cd) from simulated wastewater. Impacts of electrolysis operating parameters: current (0.56–2.8 A), rotation speed (100–500 rpm), initial cadmium concentration (20–100 ppm), and pH (3-9) were investigated. Response surface methodology and Box-Behnken design were used for optimizing the process parameters where cadmium Removal Efficiency (RE %) was selected as a response function. Findings of the present work suggested that currently has a main impact on the removal efficiency of cadmium followed by rotation speed, then concentration and pH. The results of the regression analysis showed that experimental data could be fitted to a second-degree polynomial model with value of the determination coefficient (R2) equal to 91.8 %. Optimal conditions for process parameters based on the RSM model were initial Cd concentration of 32.0 ppm, current of 2.8 A, rotation speed of 371 rpm and pH = 3, where a final cadmium concentration less than 0.3 ppm was obtained after 30 min of electrolysis process (RE= 99.28% ).

“…Response surface methodology (RSM) is a vital subject in the statistical design of experiments. It was used efficiently in different processes for wastewater treatment such as adsorption [28], disinfection of chlorine [29], electrocoagulation [30], Fenton-related process [31], electrochemical oxidation [32], and heavy metals removal [22]. Response surface methodology used a group of statistical and mathematical techniques for modeling and analyzing many problems in which various variables affected the response of the process.…”

Rotating cylinder electrodeWoven screens Copper removalResponse surface methodology A B S T R A C T Copper removal from simulated wastewater was investigated by using a rotating tubular packed bed of woven screens electrode as a cathode in a new design of the electrochemical reactor. The effects of electrolysis operating parameters like current (0.5-2.5 A), rotation speed (150-750 rpm), and initial copper concentration (100-500ppm) were investigated. Optimization of process parameters was carried out by adopting response surface methodology (RSM) combined with Box-Behnken Design (BBD), where copper removal efficiency was selected as a response function. The results indicated that the current has the main effect on the copper removal efficiency followed by rotation speed and concentration. The results of regression analysis revealed that the experimental data could be fitted to a second-order polynomial model with a value of determination coefficient (R 2 ) equal to 0.9894 and Fisher test at a value of 51.57. The optimum conditions of the process parameters based on RSM method were an initial copper concentration of 205 ppm, current of 2.5A, and rotation speed of 750 rpm utilizing cathode composed of screens with mesh no. 30 where a final copper concentration less than 2 ppm was obtained after 30 min.
