Using electrocoagulation–electroflotation technology to treat

synthetic solution and textile wastewater, two case studies

Authors Belkacem Merzouk, Khodir Madani, Abdelkrim Sekki Publication date2010/1/15 Journal Desalination Volume250 Issue2 Pages573-577 Publisher Elsevier Description

The purpose of this study was to investigate the effects of the operating parameters, such as pH, initial concentration (Ci), duration of treatment (t), current density (j), interelectrode

distance (d) and conductivity (κ) on the treatment of a synthetic wastewater in the batch electrocoagulation (EC)–electroflotation (EF) process. The optimal operating conditions were determined and applied to a textile wastewater. Initially a batch-type EC–EF reactor was operated at various current densities ranging from 11.55 to 91.5 mA/cm2 and various

electrode gaps (1, 2 and 3 cm). For solutions with 300 mg/L of silica gel, good turbidity removal (89.6%) was obtained without any coagulant when the current density was 11.55 mA/cm2, and with initial pH at 7.6, conductivity at 2.1 mS/cm: the treatment time was

hold for 10 min and the electrode gap was 1 cm. Application of the optimal operating parameters on a textile wastewater showed …
