The study investigated the reusability of greywater through an electrocoagulation process enhanced by UVA using aluminum and iron electrodes. Optimal conditions were found for pH, current density, and salt concentration, leading to significant removal of contaminants such as Escherichia coli, COD, turbidity, TSS, TN, TP, and BOD(5).
In this study, greywater reusability was investigated with UVA enhanced electrocoagulation process using aluminum and iron electrodes in a hybrid reactor. Optimum operating conditions were found as pH 7.4 and 3 mA/cm(2)for both electrode types with 1 g Na2SO4/L and in 40 min final time.Escherichia coli(E. coli), COD, turbidity, TSS, TN, TP and BOD(5)removals were found as 100, 88, 97, 62, 44, 98 and 88% with Al electrodes and 100, 79, 99, 80, 8.5, 98 and 78% with Fe electrodes, respectively. On the other hand, BOD(5)removal was efficiently enhanced using UVA irradiation for reclamation purposes of greywater.
