Abstract

Wastewater from the textile industry is very dangerous for the environment and human health. The removal of oxidizable matter from residual water from wool washing of a textile industry was investigated by discontinuous electrocoagulation (ECD), to comply with the established standards. The wastewater was characterized physicochemically before and after the treatment. The ECD was carried out in a 28 L capacity tempered glass cell, with 20 iron electrodes, where the appropriate treatment time was determined and the effect of the operating variables electric potential (4, 5 and 6 V) and distance between electrodes (2, 4 and 6 cm.) on% Chemical Oxygen Demand eliminated (COD); applying a 32factorial design. The results indicated that the studied variables had a significant effect on COD and revealed greater removal of oxidizable matter (91.43%) at 5 V conditions, 2 cm of separation between electrodes and 30 minutes of residence time. The mathematical model that relates the variables under study was determined (R2 = 99.77% and R2adjusted = 99.38%). It is concluded that the electrocoagulation process constitutes an efficient alternative for the treatment of wastewater from the textile industry.
