Dissolved organic matter (DOM) exerts a crucial role in biogeochemical processes and ascertaining water quality reservoirs, where it is vulnerable to the dynamic impacts of surface inflows. However, understanding how DOM quantity biochemical features responds hydrodynamic forces tropical reservoirs remains limited. To enhance our vertical profiles characteristics under varying (strong, moderate, weak regions) Chitian Reservoir (18°43′–18°42′ N, 109°68′–109°70′ E), December 2023, we investigated concentrations column samples using multispectral techniques, parallel factor model, two-dimensional correlation analysis. Our results indicated that (4.34 ± 0.36 mg/L) are highest reservoir center, whereas total nitrogen (0.52 0.04 mg/L), phosphorus (0.02 0.03 nitrate (1.01 0.07 present their values inlet region. As force decreases, microbial activity increases, DOM’s humification degree molecular weight decline. comprises humic-like components, including three terrestrial sources (accounting for 85.38%~87.03%) one source, with dominant allochthonous origin.

In contrast, aromatic C–H demonstrates weakest reactivity. spectral closely linked nutrient form (N P).

Biofiltration, a sustainable water treatment technology relying on microbial processes to remove contaminants, offers promising approach achieving the United Nations Sustainable Goal 6 of universal access clean and sanitation by 2030. However, key barrier optimising biofiltration is incomplete understanding biological mechanisms governing its performance. Despite numerous studies examining how engineering decisions impact biofilter performance associated microbiome, significant influence geographical location communities raises question whether these findings are universally applicable or location-specific. To address this, we conducted meta-analysis 15 microbiomes using 16S rRNA high-throughput sequencing (HTS) data, mainly originating from rapid gravity and/or granular activated carbon (GAC) filters. different types scales, results highlight as major contributor microbiome dissimilarity in samples (Top Bottom) (R2∼ 0.5; p-value<0.001). The same was observed for influent waters (PERMANOVA R2= 0.76; p-value<0.001), indicating location-specific opposed differences driven operating parameters. Irrespective location, higher percentage assembled through deterministic (∼55 %) compared stochastic (∼45 %). Finally, our suggest that depth stratification may be with enrichment taxa capable metabolising more complex organic deeper filter layers (10 enriched pathways Bottom 3 at Top). These insights provide broader offer possible research avenues targeted effective design strategies.
