Application of asymmetric current for electrocoagulation treatment of oil-containing waste water

Abstract

The goal of the work was to study the electrocoagulation of oily wastewater using an asymmetric current and to determine the composition of the resulting sludge for disposal. The planning of the experiment according to Box-Hunter method was given and mathematical models - regression equations of the electrocoagulation process of oily wastewater using an asymmetric current were obtained. Optimization was performed by the dissociative-step method due to the regression equations. The structure and composition of sludge obtained under optimal electrocoagulation conditions using asymmetric current for the disposal of sludge in the arbolite mixtures production were studied. The results of experimental studies can be used to develop low-waste efficient, energy-saving technologies for wastewater treatment and waste management.
