Self-Forming Dynamic Membrane Applied in Anaerobic Bioreactors Operating at High Fluxes for Domestic High-Strength Wastewaters Treatment André L. M. Brito, Ana C. S. Muniz, André L. F. de Brito, Evelyne M. F. Costa, Wilton S. Lopes Water and Environment Journal, 2026 Discharge of untreated wastewater is one of the main causes of environmental pollution, demanding the development of effective and affordable treatment technologies. Dynamic membrane (DM) systems emerge as a sustainable alternative due to their simplicity, adaptability and potential for high treatment efficiency. This study investigated the performance of Anaerobic Dynamic Membrane Bioreactors (AnDMBRs) treating high‐strength domestic wastewater, focusing on DM formation, dissociation and stability. Two configurations, submerged and external modules (89 μm), were operated for around 100 days under high‐flux conditions. Results demonstrated clear DM formation cycles, with COD removal efficiencies of 70.5% and 67.5% and turbidity reductions of about 78%. Permeate particle size remained below 10 μm, showing performance comparable to microfiltration. Sludge properties and zeta potential strongly influenced DM structuring, with rapid recovery after backwash. The findings underline the global strategic importance of DM technologies, offering insights to advance energy‐efficient, low‐cost, and sustainable wastewater management.
