Fine / Coarse Bubble Diffusers

Fine Bubble Diffusers

Fine Bubble Diffusers

  • Produce excess amount of tiny bubbles
  • Rise gradually from floor of waste water treatment plant
  • Bubbles diameter between 0 to 3 millimetres
  • Results in effective transfer of oxygen to the water hence energy savings
  • Presence of sewage and oxygen allow bacteria to harvest enzymes used in breaking down of waste
  • Finer bubbles allow greater aeration efficiency

Coarse Bubble Diffusers

Coarse Bubble Diffusers

  • Bubble diameter in between 3 to 50 millimetres
  • Risk of plugging reduced
  • Better mixing performance compared to fine bubble diffusers
  • Surfactants inhibit the transfer of oxygen to the water
  • Coarse bubbles rise too quick
  • Surfactants have not enough time to create the barrier
