A novel dual chemical coagulation–electrocoagulation method for enhanced NOM removal
Original language description
Natural organic matter (NOM) in drinking water sources can deteriorate the organoleptic properties of water, impair the efficiency of the drinking water treatment processes, and pose a risk of harmful disinfection by-product formation. Therefore, an efficient and economic NOM removal is crucial for the sustainable production of high-quality drinking water. The study investigates the removal of NOM from natural surface water by chemical coagulation (CC), electrocoagulation (EC), and by their combination in a single treatment step – dual coagulation (DC), using chemical Al-based or Fe-based coagulants for CC and Al and Fe electrodes for EC. It is demonstrated that the dual coagulation method with relatively low EC metal dosage surpasses the NOM removal efficiency of CC and approaches the performance of EC, which, however, may have economic or technical limitations. Furthermore, ferric coagulants in both CC and EC show superior efficacy to Al coagulants. Consequently, the combination of CC by ferric coagulant with EC using Fe electrode provides the highest NOM removal (65 %) by DC compared to 57 % removal by CC (Fe coagulant) and 69 % removal by EC (Fe electrode). The cost analysis of individual coagulation methods shows that with DC, the enhancement of NOM removal efficiency may be achieved at the lowest operating costs, compared to CC and EC.
