| Abstract: | Coalbed methane produced water (CBMPW) is characterized by high salinity and a complex mixture of organic contaminants, which severely inhibit microbial activity during treatment and consequently reduce treatment efficiency. To overcome this challenge, three aerogel-based biocarriers-chitosan aerogel (CSA), sodium alginate aerogel (SAA), and chitosan/sodium alginate composite aerogel (CS/SAA) were developed in this study. These aerogels were used as fillers in a biofilm-membrane bioreactor (BF-MBR) system. The results demonstrate that the novel CS/SAA composite aerogel possesses a high specific surface area (89.34 m2 g-1) and a stable three-dimensional mesoporous structure, which markedly enhances microbial attachment and mass transfer efficiency. In the CS/SAA-based BF-MBR system, visible biofilm coverage was observed on the CS/SAA surface within 15 days after sludge inoculation. Following 91 days of continuous operation, the system selectively enriched halotolerant microbial communities dominated by Marinimicrobium and Halomonas, achieving excellent organic matter removal performance, with average removal efficiencies of 75 % for dissolved organic carbon and 85 % for UV (Copyright © 2026 Elsevier Ltd.
