Fluoride removal by a continuous flow electrocoagulation reactor.

Methylene blue removal from aqueous solutions by electrocoagulation in continuous flow reactor: Modeling and optimization of operating parameters

Introduction The application and increasingly produce of colorants, particularly, synthetic dyes, are one of the main environmental and health concerns especially in industrialized countries. If this type of dyes is discharged into the environment without any control, many problems will arise. Therefore, it is necessary to remove the dyes from aqueous solutions using appropriate methods. The p...

Fluoride removal by using a batch electrocoagulation reactor

Electrocoagulation: Promising Technology for Removal of Fluoride from Drinking Water - A Review

Electrocoagulation has a long history as a water treatment technology having been employed to remove a wide range of pollutants. Inspite of its manifold applications the technique has never been accepted as a mainstream water treatment technology due to lack of a systematic approach to electrocoagulation reactor design, operation and the issue related to electrode dissolution over period of tim...

Performance of Continuous Electrocoagulation Process for Turbidity Removal from Sand Filter Backwash Water

The presence of particles such as algae, clay, organic materials and water-soluble substances often create turbidity or color in water. In recent years, electrocoagulation process has attracted an extensive attention due to its advantages. Since sand filters are widely used in water treatment industry and their corresponding backwash water is large in volume, turbidity removal will save water c...

Performance of an Electrocoagulation Process in Treating Direct Dye: Batch and Continuous Upflow Processes

This study presents an investigation of electrochemical variables and an application of the optimal parameters in operating a continuous upflow electrocoagulation reactor in removing dye. Direct red 23, which is azo-based, was used as a representative of direct dyes. First, a batch mode was employed to optimize the design parameters: electrode type, electrode distance, current density and elect...
