The Bio-QZ in the biogas plant: More stable processes and faster gas formation

ANDRITZ MeWa offers the complete process chain, from supply of the input material, to its disintegration, to feeding it to the fermenter. The individual process stages can be controlled through a common interface or included in the plant's overall electronic control system. In this case, the system is adapted to the individual circumstances for each plant. Existing biogas plants can also be upgraded easily with a Bio-QZ for more efficient use of gas potential.

Here you can see the many different ways off integrating our Bio-QZ into your biogas plant:

Integration of the Bio-QZ 2.0
On stilts
On the fermenter
Between hopper and fermenter
On a platform
Suitable for hopper
Mobile solution
Perfectly integrated
Optimum solution for co-fermenter plants

Process advantages with the Bio-QZ

  • High throughputs
  • Wide range of different materials
  • Much shorter dwell time in the fermenter
  • Higher gas yield due to faster gas formation
  • Packaging removed from organic material, making subsequent separation easier
  • More stable processes, stirring times halved
  • Homogeneous substrate suitable for pumping
  • Scum layers dissolve more quickly
  • Insensitive to pieces of metal and stones
  • Low wear due to operating principle without knives
  • Benefits for co-fermenters and renewable energy plants
  • Use in all proven dry and liquid feed systems
  • Easy to install in existing plants
