Organic waste
Pre-treatment
for digestion
By using the right shredding and separation technologies, contaminated biogenic waste can be recycled. The resulting liquid goes into wet digestion.
Shredding with
low speed
The process starts with the Crambo dual-shaft shredder. Its teeth and screen basket are configured for the materials. If the input contains a large amount of plastic, a combination of Terminator and screen drum can be used. Either way, the job of these low-speed shredders is to shred and open up the packaging of the organic content.
Dissolve
it
The key component of the treatment stage is the transfer of the organics into the liquid phase. The pulper used performs several tasks.In batch operations, the organics are shredded further and homogenised in the proces water. Packaging is emptied and cleansed by the high flow speed. At the same time, heavy material is seperated off through a sluice.
Separation
by screening
Raw substrate exits the pulper onto a Multistar star screen, connected downstream. The liquid with the supended organic material flows throught the star screen and is collected in a tray from where it is pumped, via sand seperation and hygenisation, into the collection tank. Oversized particles are discharged via the star screens and water is removed in a press.
Transfer to
fermenter
From the settling tank, the cleaned digestion liquid passes through a tube macerator. It then goes to an eccentric screw pump, which serves as the interface to the anaerobic digestion process.
