This work studied the reduction of humic acids (HA) by continuous electromagnetic (EM) treatment followed by electrocoagulation (EC) in batch of synthetic HA solution using two aluminium electrodes at neutral pH. After continuous EM treatment until the filling of the electrocoagulator, the solution is electrocoagulated. The pH of the HA solutions is adjusted to 12 prior to UV absorbance (300 rim) measurement to enhance HA absorbance since the best dissolution of HA is obtained in neutral or acidic pH. The laboratory tests show that EC process in batch (30 min) is highly efficient for HA removal at pH 7 (96%) and 3 (90%) and less efficient at pH 11 (51%). On the other hand, EM treatment in batch (25 min) increases the induced effect by pH adjusting of HA solution [i.e. UV absorbance decreases at pH 3 (13%) and increases at pH 7 (9%) and 11 (8%)]. However, when EM treatment is in continuous mode and taken alone, it does not have a significant effect on HA removal. When EM treatment is followed by EC in batch, it has an important contribution to increase UV absorbance removal by EC near 100% at pH 7. EM treatment seems to increase the reactivity of HA macromolecules before their removal by charge neutralisation-adsorption in the EC process.
