industrial development and extensive use of heavy metals have led to the problem of environmental pollution. nickel compounds are toxic to plants and have detrimental effects on their growth. valerian is a plant used in herbal medicine. considering the hazards of nickel, various methods have been developed to remove this contaminant from herbs irrigation wastewater, including the common chemica...

In this study, successive electrocoagulation (EC) and electro-oxidation (EO) processes were used to minimize some of the major pollutants in real wastewater, such as organics (detected by chemical oxygen demand (COD)), turbidity. The wastewater utilized present study was collected from Midland Refinery Company Baghdad-Iraq. performance batch EC-EO studied utilizing Graphite Aluminum (Al) monopo...

The aim of this paper is to investigate whether simulated Jordan refinery wastewater can be treated through electrocoagulation (EC) conform the most stringent Jordanian norms for reusing irrigation cut flowers and perform cost analysis a treatment plant whose core are EC reactors. method used estimating fixed (capital) costs taken from literature based on study estimate (factored estimate) that...

Effluents from Baker's yeast production plant contain a high percentage of color and a large amount of organic load. In the present study, Baker's yeast wastewater (BYW) is treated with the electrocoagulation (EC) process using Al electrodes. Operating parameters (pH, current density, color intensity and operating time) are optimized by response surface methodology (RSM). Quadratic models are d...

The removal of Reactive Black 5 dye in an aqueous solution by electrocoagulation (EC) as well as addition of flocculant was investigated. The effect of operational parameters, i.e. current density, treatment time, solution conductivity and polymer dosage, was investigated. Two models, namely the artificial neural network (ANN) and the response surface method (RSM), were used to model the effect...

The aim of this study was to determine the effects of main factors and interactions on the color removal performance from dye solutions using the electrocoagulation process enhanced by adsorption on Granular Activated Carbon (GAC). In this study, a mathematical approach was conducted using a two-level fractional factorial design (FFD) for a given dye solution. Three textile dyes: Acid Blue 74, ...

The applicability of iron (steel) electrodes in a continuous electrocoagulation (EC) process to treat coal seam gas (CSG) associated water comprising high level turbidity (421 NTU) was studied. Key objectives were understand the influence upon quality when hydraulic retention time (HRT) and polarity reversal (PRT) tested using bench top EC unit. Extension HRT promoted removal dissolved alkaline...

Sanitary landfill leachate (LL) composition varies according to climate variables variation, solid waste characteristics and composition, age. Leachate treatment is essentially carried out trough biological physicochemical processes, which have showed variability in efficiency appear a costly solution for the management authorities. Electrocoagulation (EC) seems suitable taking into account of ...

The aim of this study was to investigate the feasibility of two decontaminating processes, ozonation and electrocoagulation, to decolorize wastewater generated by humid finishing leather production. With the objective to determine if one or both process could remove color, benchscale experiments were conducted with three different colorants, representative of the main dye groups: di-azo (CI Dir...
