Abstract Effective treatment of livestock and poultry digestate remains challenging due to its high content refractory organic matter. In this study, a coupled anaerobic–oxic (A/O) integrated fixed–film activated sludge (IFAS) system was investigated evaluate capacity for removal molecular transformation. The IFAS outperformed the A/O system, achieving an efficiency 43%, compared 17% in process. Molecular analyses revealed distinct transformation pathways: process tended increase weight structural complexity dissolved matter, whereas promoted oxidative fragmentation, resulting formation smaller, oxygen–rich compounds. These changes were reflected key indices (DBE, NOSC, AI mod ) accumulation carboxyl–rich intermediates. Microbial community analysis associated Bacteroidota with degradation oxygenated compounds via hydrolytic processes, while Actinobacteria Deinococcota linked lignin– derived aromatics. integration advanced characterization microbial profiling highlights system’s enhanced capability both simplification biodegradation complex organics, providing promising strategy high–strength wastewater.

Submerged membrane bioreactors are effective tools for synergistic production of valuable compounds, cell retention in the bioreactor, and separation products from reaction solution. However, fouling is a problem that impairs efficiency processes involving submerged bioreactors. One mechanical methods efficient mitigation backwash. Therefore, this study investigated backwash as method mitigating biofouling ceramic specifically terms Saccharomyces cerevisiae suspension. To identify key factors affecting dynamic flux their interactions, Fractional Factorial Design (FFD) was employed based on operating variables (2 levels, 5 variables). The average model showed dependency flow rate backwash, time between cycles, duration, concentration, process (adjusted R2=0.99). Furthermore, effect recovery assessed comparison to without It found after application up 100% initial could be recovered. In contrast, only around 20% maintained optimized conditions were at 1500 mL min-1, cycles min, duration sec, concentration 20 grams dry weight per liter, 0.5 h. mechanism determined deposition yeast cells surface blocking pores inside by sorbitan monostearate reagent present
