Abstract
The main objective was to develop a wastewater treatment system by means of the electrocoagulation method according to the parameters of Chemical Oxygen Demand (COD) and Total Suspended Solids (SST). The results obtained were that at a pH of 6 and 7 with a contact time of 30 minutes, the highest percentage of removal of SST (98%) and COD (90%) was obtained. Once the conductor was selected, tests were carried out at different pH (6, 7 and 8) with contact times of 15, 30 and 45 minutes each, at 12 V and 0.4 A. A Multifactorial ANOVA statistical test was performed to determine if there were significant differences between the treatments. Once the results were evaluated, a prototype of approximately 38 L was designed with parallel plates with results of removal of SST of 93% and COD of 66%. The approximate cost of treatment per cubic meter is $ 35
