“…These processes include two-phase bioreactors, moving-bed biofilm reactors (MBBRs), and immobilized cell biofilm reactors [128]. The enhancement techniques involve bioaugmentation, introducing specialized microbial cultures [129,130]; bioacclimation, adapting microorganisms to degrade novel or toxic compounds [131,132]; and biostimulation, optimizing environmental conditions to increase microbial activities [133,134].…”

“…Factors such as the specificity of microbial consortia, bioreactor design, and operational conditions affect the efficacy of advanced biological treatments. While these methods offer the advantage of targeting persistent micropollutants more effectively than conventional biological treatments, they also face challenges, including increased operational costs, system complexity, and maintenance demands [129,[134][135][136].…”

The global concern regarding the release of micropollutants (MPs) into the environment has grown significantly. Considerable amounts of persistent micropollutants are present in industrial discharges. Depending solely on a singular treatment approach is inadequate for the effective removal of MPs from wastewater due to their complex composition. The performance of different treatment methods to meet the discharge standards has been widely studied. These efforts are classified as hybrid and sequential processes. Despite their adequate performance, the optimization and industrial application of these methods could be challenging and costly. This review focuses on integrated (sequential) and hybrid processes for MP removal from actual wastewater. Furthermore, to provide a thorough grasp of the treatment approaches, the operational conditions, the source of wastewater containing MPs, and its characteristics are detailed. It is concluded that the optimal sequence to achieve the removal of MPs involves biological treatment followed by an advanced oxidation process (AOP) with a final passage through an activated carbon column. To refine this process further, a membrane unit could be added based on the desired effluent quality. Nevertheless, considering practical feasibility, this study identifies specific areas requiring additional research to implement this integrated treatment strategy effectively.
