In order to manage water resources in countries with water crisis, recycling of water in houses can be a practical strategy. The usage of advanced oxidation processes (AOPs) is an efficient way when a low volume of wastewater is considered. In this work, a real washing machine effluent (WME) was treated by four electrochemical advanced oxidation processes. Electro-Fenton (EF) and photoelectro-Fenton (PEF) processes are combined with peroxymonosulfate (PMS) to treat WME. Heterogeneous iron-based catalyst (Fe3O4, MNPs) was synthesized as catalyst for all processes. The characteristics of MNPs were determined by several techniques. All operating parameters were investigated for EF, PEF, EF/PMS and PEF/PMS. PEF/PMS process removed nearly complete organic compounds (99.5% of chemical oxygen demand and 97.1% of total organic carbon) under the conditions of pH = 5.0, 30 mA/cm(2), MNPs = 100 mg/L, 2 mM PMS and 180 min reaction time. MNPs function was without change after three times usage. The results indicated that PEF/PMS can be a new system for treatment of effluents such as greywater, washing machine etc. for the application in household scale to reduce water consumption. (AU)
