In the face of escalating challenge sludge production and disposal in wastewater treatment plants (WWTPs), situ reduction biotechnology (ISRB) has recently emerged as a highly promising strategy. It not only potential to curtail generation at its origin but also ensures sustained efficiency process. Several key strategies have demonstrated exceptional harnessing microbial processes for degradation. They encompass enzymatic hydrolysis, inoculation, protozoan/metazoan predation, bacteriophage lysis, biofilm-based manipulation. Compared traditional methods (e.g., incineration landfilling), these biotechnologies offer significant advantages through lower costs, reduced energy consumption, minimal environmental impacts. The efficacy ISRB is substantially affected by various factors, where pH, shift, nutrient conditions play crucial roles. Despite notable progress made this field, challenges persist when it comes scaling up technologies more extensive widespread applications. This review comprehensively highlights fundamental mechanisms, application strategies, future prospects ISRB, including one first studies introduce bacteriophage-based approaches reduction, offering novel perspective on phage-mediated control. By doing so, aims in-depth insights into role sustainable solution management, paving way further research development area biotechnology.

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.
