Considerations on the design and financial feasibility of full-scale membrane bioreactors for municipal applications.

摘要: Based on the practical experience in design and operation of three full-scale membrane bioreactors (MBR) for municipal wastewater treatment that were commissioned since 1999, an overview different concepts applied to MBR plants is given. The investment costs energy consumption MBRs conventional activated sludge (CAS) (with without tertiary treatment) Erft river region are compared. It found specific lower than those comparable CAS with treatment. A comparison demand WWTPs structure actual operational analysed. can be seen only responsible one quarter third all expenses. a rough empirical cost data, carried out. In this example employs sand filtration disinfection order achieve effluent quality. influence lifetime life cycle assessed.
