This study evaluated the filtration performance and energy consumption of three different reverse osmosis (RO) membranes (ESPA2-LD, RE4040-BE, TMG10D) for treating semiconductor wastewater. A ceramic membrane combined with ozone RO pre-treatment influence injection on efficiency were investigated. flat-sheet comprising Al2O3/SiO2-ZrO2 was used to treat real synthetic wastewater as feed water. The deionized water (DI) permeabilities 144.6, 94.22, 156.6 LMH/bar, respectively. microfiltration process that reduced permeability all processes, total organic carbon (TOC) removal rate decreased when applied. application power inconclusive, its effect unclear indicating an increase 3.37%, 4.48%, 11.6% filtrated ozone, TMG10D showed highest followed by ESPA2-LD both, wastewaters. However, salt TOC rejection RE4040-BE TMG10D. exhibited lowest per ton filtered RE4040-BE. determined be most suitable in terms quality stability
