Treatment of Effluents from the Wool Washing Process in a Textile Industry Through Electrocoagulation

EasyChair Preprint no. 5798

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 32 factorial 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.
