The performance of electrocoagulation using iron electrodes for the removal of hexavalent chromium from synthetic aqueous solutions and actual industrial electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, applied current density, initial metal ion concentration, COD and time of electroprocessing were investigated. The optimum pH was f...

Background: Car wash wastewater contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. In this study, the application of electrocoagulation (EC) to treat car wash wastewater has been studied, and the operating parameters optimized. The electro-Fenton (EF) for further contaminant removal was also investigated. ...

Agitation was a significant factor in achieving the high performance of electrocoagulation (EC) system. Three EC systems with four parellal monopolar Al electrodes were established to clarify influence agitation methods on pollutants removal efficiency; magnetic stirring, continuous aeration, and combination stirring aeration. The aim this work maximize industrial wastewater treatment short det...

Saline waters treatment has become increasingly important for drinking water supply in a greater part of the world. However, some serious limitations had recently been discovered during water treatment, among them the boron problem seems to have a critical meaning. According to the WHO regulations (2011), the boron concentration should be reduced to less than 2.4 mg/L for drinking water. The pu...

This study investigated the effects of four operational and environmental variables on the removal of trace metal contaminants from drinking water by electrocoagulation (EC). Removal efficiencies for five metals (arsenic, cadmium, chromium, lead and nickel) were compared under varying combinations of electrode material, post-treatment, water composition and pH. Iron electrodes out-performed alu...

Restaurant wastewater contains a high concentration of O&G, up to 3434 mg/L. This study aims (a) assess the efficiency EC combined with US methods for O&G removal in restaurant wastewater, (b) identify optimum condition COD degradation using treatment via response surface methodology (RSM), and (c) determine morphological aluminium (Al) electrode before after treatment. The samples were...

The high concentration of sulphates is detrimental to the infrastructure wastewater treatment plants. Hence in this study, we present application electrocoagulation sludge as an adsorbent remove from industrial effluents before they are released back environment. contains iron and aluminium cations cationic complexes that precipitate water. Corrugated sheet was used a sacrificial electrode duri...

A variable order kinetic (VOK) model derived from the Langmuir equation was applied to specify the kinetics of the fluoride removal reaction for electrocoagulation (EC). Synthetic solutions were employed to elucidate the effects of the initial fluoride concentration, the applied current and the initial acidity on the simulation results of the model. The proposed model successfully describes the...

Electrocoagulation (EC) is one of the emerging technologies in groundwater and wastewater treatment as it combines benefits coagulation, sedimentation, flotation, electrochemical oxidation processes. Extensive research efforts implementing EC technology have been executed over last decade to treat chemical oxygen demand (COD)-rich industrial wastewaters with aim protect freshwater streams (e.g....
