Electrocoagulation Treatment of Oily Wastewater in the Oil Industry

Electrocoagulation as a Wastewater Treatment

Coagulation and flocculation are traditional methods for the treatment of polluted water. Electrocoagulation presents a robust novel and innovative alternative in which a sacrificial metal anode doses water electrochemically. This has the major advantage of providing active cations required for coagulation, without increasing the salinity of the water. Electrocoagulation is a complex process wi...

Treatment of wastewater by electrocoagulation: a review.

The electrocoagulation (EC) process is an electrochemical means of introducing coagulants and removing suspended solids, colloidal material, and metals, as well as other dissolved solids from water and wastewaters. The EC process has been successfully employed in removing pollutants, pesticides, and radionuclides. This process also removes harmful microorganisms. More often during EC operation,...

Removal of Crude Oil from Oily Artificial Wastewater by Using Pulse Electrochemical Treatment

In this study electrocoagulation (EC) process with sacrificial aluminum anode was used to separate crude oil from synthetic oily wastewater emulsion. A preliminary experimental study was performed to evaluate the most accurate operating parameters, which are then used for the determination of crude oil removal efficiency. The experimental results indicated that electrocoagulation was very e...

Ozone and Electrocoagulation Processes for Treatment of Dye in Leather Industry Wastewater: A Comparative Study

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...
