Wastewater-borne virus pose significant risks to both environmental ecosystems and public health. Removal of from wastewater requires a rigorous treatment regime. Membrane bioreactor (MBR) systems are at the forefront contemporary technologies, offering robust barrier against viruses. This review outlines dual functionality MBR systems, which combine membrane filtration with biological processes efficiently target removal. It highlights role biofilm (cake gel layers) formed on surface, along critical influence pore size. further explores various operational parameters that maximize removal in MBRs, particularly highlighting aging cleaning. The impact varies as chemical due harsh cleaning agents tends reduce efficiency by enlarging pores, whereas natural can enhance capture development irreversible fouling. limited research effects flux, pH aeration condition has resulted varying inconclusive findings. systematically investigates correlation between such turbidity, mixed liquor suspended solids, transmembrane pressure, solids retention time, temperature, hydraulic time their efficacy. Turbidity pressure identified potential indicators for indirectly monitoring By integrating these insights, this paper contributes an depth understanding efficacy ongoing refinement strategies ensure water safety sustainability.
