Cost Estimation of Pilot-scale Membrane Bioreactor

摘要

Membrane bioreactor is generally a term used to define wastewater treatment techniques where a perm-selective membrane for example microfiltration or ultrafiltration, it is integrated with a biological process specifically a suspended growth bioreactor. Membrane Bio Reactors (MBRs) differ from ‘polishing’ techniques where the membrane is employed as a discrete tertiary therapy step with no return of the active biomass to the biological process. Membrane Bio Reactors (MBRs) consist of a biological reactor with suspended biomass and solids removal through ultrafiltration and microfiltration membranes. These can be used for industrial wastewaters. The primary disadvantage of Membrane Bio Reactors (MBRs) systems is the generally higher capital and operating costs than conventional systems for the same through put.
