Overview

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 (60 min + 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
• clean water mixing applications
• mixing objectives, design criteria and constraints
• liquid blending design criteria: flow regime; blend time; mixture quality (coefficient of variation); pressure drop; installation size/length
• performance of equipment for blending in pipes, channels and flash mixers
• dosing into ‘empty’ pipes and channels, jet mixing in pipes and channels.
• static mixers in pipes and channels - all common types/manufacturers in use covered eg twisted, structured and vortex generating by Chemineer, Sulzer, Statiflo, Westfal
• orifice plates, baffled channel mixers, weirs and flumes
• stirred tank flash mixers
• effect of additive physical properties (viscosity and density) on blending performance
  comparative mixer efficiency
• energy consumption and time required to achieve specified mixture quality (CoV)
• application and cost saving examples

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.
