This work studies the electrocoagulation (EC) process for the treatment of colored solutions of two dyes used in the textile industry: direct brown 2 (DB) and BF cibacete blue (CB) using aluminum electrodes in batch mode. Key EC parameters are investigated. The pH effect is found to be more important than the supporting electrolyte on the electrochemical process. The best EC efficiencies are as follows: for DB, 99.89% removal at 40 mg/L (pH 10, U = 12 V, tEC = 60 min); and for CB, 99.74% removal at 40 mg/L (pH 2.5, U = 12 V, tEC = 60 min). The power consumption is 16.56 and 17.04 kWh/m3 for DB and CB, respectively. Copyright © Taylor & Francis Group, LLC.
