Vortex Module for Anaerobic Digester

 

vortex 1

 

TERIX-Envirogaz’s process uses a mixing system that creates a movement optimized for anaerobic digestion, thus preventing the formation of crusts and the accumulation of deposits. The system, installed in each digester, creates a vortex that keeps solids from SOFs in an homogeneous suspension and maintains a constant temperature, which optimizes process efficiency and performance.

 

Benefits

  • Jets create a vortex that optimizes the digester’s productivity
  • Mixes SOFs at various levels inside the digester
  • No moving components inside the digester, thus preventing maintenance inside the unit
  • Allows for the mixing of various digesters through one central pumping system
  • Pumping assembly easy to access and protected from adverse weather
  • Platform or in-container plant assembly for ease of installation

 

 
Mixing System Characteristics  
  • Ensures an homogeneous mix in all types of digesters, regardless of the level of SOFs inside, thus providing highly flexible operations

  • All mechanical components are located outside the digesters, thus ensuring ease of maintenance and operator security

  • Injection nozzles are located along the height of the digester, thus creating a vortex from top to bottom                                           

  • Feeders are pre-assembled on a platform or in a container, thus reducing on-site assembly time and ensuring product quality

  • Uses six to ten nozzles, based on digester size, for increased performance

  • Works intermittently, which generates considerable energy savings
