Wafer static mixers are designed to sandwich between pipe flanges.  The simple, short lay length design can provide a mixing solution when there is not room or budget to install a more sophisticated static mixer.


When to use a Wafer Static Mixer

Wafer static mixers are a good choice for applications that require the mixing of aqueous or near water-like chemicals.  They are best used for water treatment applications including:

  • Chlorination
  • Coagulation
  • Ammonia addition
  • Methanol addition
  • Hydrogen peroxide
  • Antiscalants
  • Corrosion inhibitors
  • Diluted polymers
  • Dilute acids
  • Caustics
  • Iron solutions


 When not to use a wafer static mixer

 Wafer mixers will generally not supply enough mixing energy for viscous chemicals such as:

  • Concentrated sulfuric acid
  • Neat (undiluted) polymer solutions

The key to a successful wafer mixer solution:

  • Ensure the size of the mixer is high enough to create fluid velocities in the pipeline in the range of 1.5 to 10 ft/sec.   This velocity is converted to mixing energy that be used to mix your chemical solution.
  • Make sure that the minimum/maximum flow rates under all conditions do not vary over about a 4:1 ratio.  If your peak maximum velocity is about 9 ft/sec, the minimum velocity cannot be lower than about 2.3 ft/sec.
