Biofiltration

Biofiltration


Technology feature: Use microorganism to biodegrade pollutants, microorganisms attached to filtering materials’ surfaces, when water passes through this filtering layer, pollutants are degraded.
Advantages:
– Low investment.
– Less energy required, comparing to activated sludge technologies.
Disadvantages:
– Subject to clogging.
– Small capacity.
– Susceptible to odor generation.
– Sensitive to temperature.
Application:
– Factories, hospitals.
– Small to medium capacity.

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.

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.
