Case Study - Desulphurisation Net Replacement

Plant Type
Agri Biogas Plant
Autumn 2019
Reason for activity:

Eco net sagging into digester surface and concerns over snagging on paddle mixer causing a major issue and retrieve and replace three mixers.

How we helped:

Utilising our previous experience of similar issues, Birch Solutions was able to rapidly identify the issues and develop a resolution plant that involved the replacement of the Eco-net and mixers on the 5,600m3 digester.

Elements of the work included:
  • Development of project plan and associated project and safety documentation
  • Safe de-commissioning for the digester prior to starting work
  • Removal of the bio-dome and eco net
  • Retrieval and replacement of three submersible mixers
  • Replacement of Econet and support straps
  • Re-installation of double membrane bio-dome
  • Development and implementation of re-commissioning plan
  • Start up and re-commissioning support
Continued support provided:
  • Service and maintenance support
  • Supply of parts
