Mixing in Sludge Treatment

Mixing in Sludge Treatment
  • Date From 13th February 2020
  • Date To 13th February 2020
  • Price Free of charge
  • Location Online

Mick Dawson of BHR gave a wonderful presentation on Mixing for Chemical Assisted Sedimentation & P Removal at our Mixing in the Water Industry event.

Unfortunately the webinar broke down and the recording was unusable. He has kindly offered to deliver an extended (60min + 30 min questions) repeat of this, along with a second webinar on potable water mixing and a third on sludge mixing.

Mick’s presentation will cover:

  • Background
  • Mixing Operations
  • Sludge Rheology
  • Sludge Mixing Applications
  • Mixing Objectives, Design Criteria and Constraints
  • Liquid Blending design criteria: flow regime; blend time; mixture quality (Coefficient of Variation)
  • Solids Suspension/Draw down design criteria: bulk flow velocity [m/s], critical shear stress [Pa], installation size/length
  • Solids Distribution design criteria: bulk flow velocity [m/s], solids concentration variation [-].
  • Circulation & Flow-pattern design criteria: Active volume [%], Residence Time Distribution (RTD); Back-mixed v Plug Flow; number of stirred tanks in series, degree of short circuiting
  • Inline Chemical Conditioning of Sludge
  • Mixer types: Simple T mixers, Jet Mixers, Orifice Plates, Valves, Pumps, Static Mixers, Dynamic Inline Mixers
  • Anaerobic Digester Mixing & Sludge Tank Mixing
  • Mixer types: Top mounted impellers, Submersible mixers, Jet mixers, Gas mixers, Draft Tube Mixers

This webinar will benefit anyone involved in potable treatment, and by the end, you'll know how to at least specify mixing for potable treatment.
