Treatment of landfill leachate mixed with municipal wastewater having a complex chemical composition with high COD,TSS, NH3, NO3, and PO4 had been studied by several researchers using various conventional techniques (Mojiriet al. 2021).For instance, Chakraborty et al. (2020) tried a combination of sequencing batch reactor (SBR) and EC for co-treatment of landfill leachate and municipal wastewater with EC followed by SBR treatment.
