For the efficient processing of fermentation residues, our high-performance GEA decanters reliably separate solid particles, dewater them into a pourable dry consistency, and guarantee a high content of up to 30% dry substance in the solids. Compared with other technologies, there is no risk of blockage with centrifugal technology and the separation of solids is more efficient. Our customers benefit from lower transport and spreading costs, as the high separation efficiency of our decanters ensures a high proportion of organic content in the solids that are spread. Moreover, for lower fresh water consumption, the clear centrate water can be fed back into the fermentation process.
GEA decanters are also designed for processing raw slurry and offer users a range of advantages. They can be used to reduce phosphate and nitrogen content efficiently, for example from liquid pig slurry, by separating up to 75% of the phosphate compounds and up to 35% of the nitrogen compounds with the solids. The pourable solids can be composted and used as high-grade fertilizers. The liquid phase is transported to a silo for storage or spread on agricultural land.
Concentrating slurry in an evaporation plant has also been proven as effective to counter the surplus of slurry, particularly in cattle-strong rearing farms. In this process, the slurry is concentrated up to 30% dry substance in an evaporation plant then completely dried in a dryer. Both the evaporation plant and the dryer can be operated here entirely with the aid of waste heat, which is often available.
Advantages:
GEA further supplies equipment like jet and vacuum pumps for conveying liquids such as biological sludge or manure and solids such as sand and gravel.
地球温暖化の影響は世界中でますます明らかになっています。あらゆる地域の町や都市が同じ課題に直面しています。それは、信頼性が高く、手頃な価格で、持続可能な供給源からの熱を地域社会に供給することです。GEAは、この分野の専門家であるGEA Heating & Refrigeration TechnologiesのヒートポンプマネージャーであるKenneth Hoffmannに、地球温暖化への迅速な対応について話を聞きました。
