Abstract

The Electrocoagulation/Electroflotation process is one of the successful methods in dyes wastewater treatment. This process by direct current electrical and metal electrodes can be removal of contaminants. The aim of this study was optimization of affecting parameters in (EC/EFP) by titanium and aluminum electrodes for decolorization of Acid Black 1 (AB1) from aqueous. In this study was used of four titanium and aluminum electrodes. By applying an electric current in 10-30 V range with control of ampere, initial pH in 5- 9 range and initial concentration of dye in 50-500 mg/L range study was done. The results indicate when pH=5, voltage and initial concentration were 30 V and 50 mg/L respectively the high efficiency of decolorization by EC/EFP done. Therefor this process has a good ability in dye removal. Efficiency of process decreased by changing the parameters.
