effective aeration

  • Aerobic treatment requires sufficient oxygen
  • Aeration achieved using coarse bubble spargers
  • Correct biomedia helps to break up bubbles, slows the bubble rise rate, achieves high oxygen transfer efficiency
  • Aeration controlled using ball valves

Water clarification

  • LBiofilm sloughs off media and is carried to the settler
  • Tube settlers increase surface area while allowing higher rise rates
  • Tube settler installed when higher rise rates are required
