Seasonal variations in feed-water chemistry and fouling dynamics of reverse-osmosis systems: A global climate lens
منشور في 2025"…First, climate-specific seasonal fouling regimes are distinct and mechanistically predictable patterns: arid coasts (BWh) experience summer biofouling synergistically amplified by gypsum scaling; temperate systems (Cfa, Dwa) face winter organic fouling from recalcitrant humics despite reduced microbial activity; and tropical intakes (Aw, Am) endure monsoonal pulses that increase both colloidal fouling and dissolved organics by 5–100× relative to dry-season baselines. …"
