Moving – bed bioreactor (MBBR)

Moving - bed bioreactor (MBBR)


Technology feature: Use microorganism to biodegrade pollutants, adding moving biofilm carrier to increase microorganism concentration retained in treatment tanks.
Advantages: Smaller occupied area and HRT than conventional AO/ A2O.
Disadvantages: Increase expense on biofilm carrier cost and maintenance cost.
Application:
– Waste water with biodegrable pollutants.
– Average-area WWTP.



Other technology


Biofiltration
Biofiltration

Use microorganism to biodegrade pollutants, microorganisms attached to filtering materials’ surfaces, when water passes through this filtering layer, pollutants are degraded.

Membrane bioreactor (MBR)
Membrane bioreactor (MBR)

Use microorganism to biodegrade pollutants, with physical membrane added.

Sequencing batch reactor (SBR)
Sequencing batch reactor (SBR)

Use microorganism to biodegrade pollutants, all reaction steps occur in one tank only and treatment occurs as batch.
