Silicon Carbide Membrane in MBRs – Not a New Kid on the Block!

Silicon carbide (SiC) membranes in membrane bioreactors are demonstrated as a durable alternative to conventional polymeric membranes, with operational experience exceeding seven years across 25+ installations in North America. SiC’s inherent hydrophilicity and chemical resistance eliminate typical fouling degradation mechanisms, maintaining consistent performance and enabling aggressive chemical cleaning protocols. Case studies from municipal and industrial applications show TMP values 12 caustic, <2 acid) and cumulative chlorine exposure up to 480,000 ppm·hours, providing operational flexibility for challenging wastewaters with high fouling potential and enabling reduced chemical cleaning frequencies.
