- - - - Depth Filtration(membrane filtration)
      - Cake Filtration or Surface Filtration
    - - const. Pressure
      - const. rate
      - Variable Pressure&Rate
    - - Pressure
      - Vacuum
- - - - Autotrophic Bacteria
        
        use CO2 as carbon sources
        
        electron acceptor = O2
      - Heterotrophic Bacteria
        
        use organic material as carbon sources
        
        electron acceptor= Nitrate,Sulphate, CO2
  - - - growth around 6.5 and 7.5
      - can't tolerate in pH>9 or <1
    - - growth around 5.6
