Aerobic granulation formed stable granules within 42 cycles, reducing sludge volume index. Increased cell hydrophobicity appears crucial for aerobic granule formation and stability.

Area of Science:

  • Environmental microbiology
  • Biotechnology
  • Wastewater treatment

Background:

  • Aerobic granulation is a key process in wastewater treatment, forming dense microbial aggregates.
  • Understanding the factors influencing aerobic granulation is essential for optimizing reactor performance.

Purpose of the Study:

  • To investigate the formation and characteristics of aerobic granules in a sequential sludge blanket reactor.
  • To explore the role of cell hydrophobicity in the granulation process.

Main Methods:

  • Operation of a column-type sequential sludge blanket reactor with acetate as substrate.
  • Monitoring of sludge volume index (SVI) and granule size.
  • Microstructural analysis using scanning electron microscopy (SEM).
  • Measurement of cell hydrophobicity.

Main Results:

  • Aerobic granules with a mean diameter of 0.35 mm formed by cycle 42.
  • Sludge volume index decreased to an average of 50 mL/g during stable granulation.
  • Rod bacteria were dominant in granules, which exhibited cavities.
  • Cell hydrophobicity increased by approximately 50% after granulation.

Conclusions:

  • Aerobic granulation can be effectively achieved in a sequential sludge blanket reactor.
  • Increased cell hydrophobicity is strongly correlated with aerobic granule formation, likely by promoting cell attachment and interaction.
