Membrane Bioreactor Technology - An Overview
- 6. Two main process configurations of biomass rejection MBRs are as follows: (i) Submerged or Immersed MBR (iMBR) In the submerged MBR (SMBR) process, the membrane is submerged directly in the aeration tank. By applying low vacuum or by using the static head of the mixed liquor, effluent is driven through the membrane leaving the solids behind. (ii) External / Sidestream MBR (EMBR) In the external MBR (EMBR), the mixed liquor is pumped from the aeration tank to the membrane at flow rates that are 20–30 times the product water flow to provide adequate shear for controlling solids accumulation at the membrane surface. The high cost of pumping makes EMBR system impractical for full-scale municipal wastewater treatment plants
