Membrane Bioreactor System

OUTFLOW MEMBRANE BIOREACTORUntitled-221

OMBR is utilized as a conventional biological treatment process, but microorganisms are separated from the exit water with UF or MF membranes. Wastewater is pumped to the bioreactor and the biomass working together with the oxygen fed by the diffusers in the bioreactor completes the biological decomposition. Later, biomass which is constantly decomposed with UF membranes, is fed back to the bioreactor.

SUBMERSION TYPE MEMBRANE BIOREACTOR

Untitled-23-300x288STMBR is utilized as a conventional biological treatment process, but microorganisms are separated from the exit water with UF membranes. UF membranes are inside the biomass in this system, and periodically continue the backwash process with air and water. Wastewater is pumped to the bioreactor, and the biomass working together with the oxygen fed by the diffusers in the bioreactor completes the biological decomposition. . Later, biomass which is constantly decomposed with UF membranes, is fed back to the bioreactor. UF membranes could be situated inside the bioreactor or in a separate tank.

ANAEROBIC MEMBRANE BIOREACTOR

Anaerobic membrane bioreactors have performed greatly in the studies conducted in recent years. High quality exit water, high treatment performance, and high biogas production are the outcomes of this system. The difficulty to operate with conventional anaerobic reactors makes it hard to obtain constant high quality exit water. It was observed that the performance of the biomass is affected negatively from the fast transition. This system provides stable high quality exit water, high treatment productivity rate, and the sludge is not affected.

  • No need for granular sludge which is hard to grow.
  • No need for three phase separation work.
  • It is possible to operate it even with high rates of salt.
  • Oil presence is less harmful.

By means of this system, it is possible to upgrade the existing anaerobic systems.
