| Περίληψη: | This study demonstrates the feasibility and performance of a pilot-scale hybrid membrane-aerated biofilm reactor (MABR) equipped with an innovative gear-structured polyethylene membrane. Over 210 days of continuous operation, the integrated system-comprising an anaerobic tank, a hybrid MABR tank, containing 2-16 cassettes within a membrane module, and an aerobic tank-achieved removal efficiencies of 88 ± 12% for BOD, 40 ± 14% for total nitrogen, and 90 ± 14% for ammonia. The total sludge yield was 0.20 kg-TSS/kg-COD (Copyright © 2026 Elsevier Ltd. All rights reserved.) |
