Substrate dissolution technology for biogas plants
Efficient preparation and application of complex substrates in a single system
Not all substrates can be metered evenly or fed directly into the fermenter. Disruptions in the material flow are particularly common with fibrous, heterogeneous, or structurally complex materials. This is precisely where our disintegration technology comes into play: it specifically prepares the substrate, homogenizes its structure, and then ensures reliable and controlled feeding into the fermenter.

FAQ
Frequently Asked Questions About Digestion Technology in Biogas Plants.
When do I need a digestion process in a biogas plant?
A disintegration technique is always used when substrates cannot be conveyed evenly or when disruptions in the material flow occur regularly.
Typical signs:
– blockages in the feed system
– uneven substrate structure
– fluctuating plant operation
– increased wear
In these cases, processing the substrate ensures more stable and reliable operation.
Which substrates require dissolution before application?
Disintegration is particularly useful for substrates with a complex structure and high heterogeneity. These include: solid manure, grass, whole-plant silage (GPS), organic waste, and mixed substrates. The more uneven the structure, the more important it is to process the material thoroughly before application.
Can the resolution technology be integrated into existing systems?
Generally speaking, yes. Whether integration into your system is possible must be assessed on a case-by-case basis. Please feel free to send us an inquiry.
This is particularly true for:
– retrofit projects
– frequent malfunctions
– increasing performance requirements
where the feed-in technology can be specifically optimized—often with relatively little structural work.
How does substrate preparation affect wear and maintenance?
The disintegration and homogenization of the substrate significantly reduces the mechanical stress on the feeding system.
This results in:
– longer component service life
– less wear on augers and conveyor systems
– reduced maintenance requirements
This is a decisive advantage, particularly when handling abrasive or fibrous materials.
