Abstract

EFFECT OF ELECTROCOAGULATION ON ZETA POTENTIAL DURING TREATMENT OF ACIDIC TEXTILE WASTEWATER

Zaina Zaroual*, Eric Chainet, Sanae El Ghachtouli and Mohammed Azzi

ABSTRACT

The study focused on determining the optimal conditions for better treatment by electrocoagulation in "batch" mode using an iron anode to treat acidic dye discharges. Particular attention is paid to the effect of electrocoagulation on the behavior of flocs through the measurement of their zeta potential. The results obtained made it possible to advance hypotheses on the mechanism governing the purification of acidic textile wastewater by electrocoagulation.The influence of various parameters on the quality of treatment and on the value of the zeta
potential such as the initial pH of the solution, the electrolysis time and the electrolysis current density, were studied.Indeed, for a pH = 7, the elimination of the color reaches 100% while the chemical oxygen demand (COD) only reaches 43% for an electrolysis time of 5 minutes and a current density of 24 mA/cm².
