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.

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.

The decanter’s hour has come as soon as the solids content in the suspension to be processed is particularly high. These machines provide the benefits of high clarifying efficiency and maximum dewatering as well as the separation of liquids with the simultaneous removal of solids. The main requirements in this respect include a high bowl speed, a...
Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids and for the production of vacuum in which a gaseous or liquid medium serves as the motive force.

The impact of global warming is increasingly apparent all over the world. Towns and cities everywhere face the same challenge: providing their communities with reliable, affordable, sustainably sourced heat. GEA spoke with an expert in the field, Kenneth Hoffmann, Manager, Heat Pumps at GEA Heating & Refrigeration Technologies, about tackling global warming faster.
Something caught Farmer Tom's eye. Instead of another product demo, GEA showcased innovations via AR. That's only the start of GEA's interactive digital farm.
GEA scientists are working with researchers at the Graz University of Technology to configure a homogenization process and technology that turns eucalyptus pulp into 3D-printed, organic structures mimicking human veins, arteries and other tissues.
