Membrane Bioreactor (MBR)

MBR is a new waste water treatment process which integrates the advanced membrane separation technology with the conventional biological treatment process. It utilizes the micro porous structure of the membrane to retain the aerobic and anaerobic bacteria in the reactor, and increases the degradation efficiency of COD, BOD via increasing the biomass concentration, extending the solid retention time (SRT). Meanwhile, MBR systems result in an excellent effluent quality and minimal footprint.

There are two main models for MBR: Hollow Fiber and Flat Sheet. Based on the outstanding R&D strength of the group and its German subsidiary R&D capability in the field of MBR, Suntar has developed a novel model of MBR: Sheet MBR. This module combines the advantages of both Hollow Fiber and Flat Sheet modules meanwhile overcomes their shortcomings, finally it features as:

  • Improved performance
  • Optimized energy consumption
  • Ecological- friendly membrane cleaning process
