Experimental data for CAPEX/OPEX calculations was obtained in an AnMBR system featuring industrial-scale hollow-fiber (HF) membranes. Results showed that operating at J(20) slightly higher than the critical flux results in minimum CAPEX/OPEX. The minimum filtration process cost ranged from Euro0.03 to Euro0.12 per m(3), mainly depending on SGD(m) (from 0.05 to 0.3 m(3<bold>)m(</bold>-2<bold>)h(</bold>-1)) and MLSS (from 5 to 25 g<bold>L</bold>-1). The optimal SGD(m) resulted in approx. 0.1 m(3<bold>)m(</bold>-2<bold>)h(</bold>-1).Reserva de todos los derechosSubmerged anaerobic MBR (AnMBR)CAPEX,OPEXIndustrial-scale hollow-fiber membranesUrban wastewater (UWW)TECNOLOGIA DEL MEDIO AMBIENTEINGENIERIA HIDRAULICAArtículo10.1080/01496395.2015.1094092Abierto
