Technology feature: Use microorganism to biodegrade pollutants, all reaction steps occur in one tank only and treatment occurs as batch.
Advantages:
– Automatic operation.
– Reduce equipments of sedimentation tank.
– Sludge recirculation is not needed.
Disadvantages:
– This technology requires open tank, so it does not fit with WWTP requires all underground tanks.
– This technology requires high degree of automation, so in case any incident happens, manual operation is difficult.
Application:

– To treat urban & domestic waste water, industrial zone waste water.

– Large scale projects.

– 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.

Moving - bed bioreactor (MBBR)
Moving - bed bioreactor (MBBR)

Use microorganism to biodegrade pollutants, adding moving biofilm carrier to increase microorganism concentration retained in treatment tanks.
