Waste pretreatment unit

By using the right shredding and separation technologies, contaminated biogenic waste can be recycled. The resulting liquid goes into wet digestion. In this process, various types of organic waste are prepared for liquid digestion. They can include packaging and contamination. Pre-shredding prepares the material for subsequent dissolution and contrary separation. The resulting liquid has ideal properties for simple digestion and at the same time ensures a long service life of the digesters. In the digester, biogas is produced from the substrate. Depending on the site conditions, it can be converted into electricity or further processed for use in the gas grid. Preparation of digestion liquid is an all-in solution, consisting of machines, electrics, pipelines and all measuring and control equipment. 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 Iow-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 operation, the organics are shredded further and homogenised in the process water. Packaging is emptied and cleansed by the high flow speed. At the same time, heavy material is separated off through a sluice.
