Mixer Replacement

Reason for activity

The customer was experiencing issues with insufficient mixing on their plant, resulting in poor and fluctuating gas production, and unpredictable performance.

How we helped

Birch Solutions were able to rapidly identify the issues and develop a resolution plant which involved the replacement of the two paddle mixers on the 3,500m digester using parts held in stock by Birch Solutions.

Elements of the work included:

  • Partial removal of the double membrane bio-dome and eco net
  • Recovery of grounded submersible mixers
  • Installation of replacement of submersible mixers
  • Inspection of eco-net and all visible panels and instrumentation
  • Re-installation of double membrane bio-dome and eco net
  • Start up and re-commissioning support
