Agricultural biomass
Manure
Liquid manure from the agricultural sector represents a valuable natural fertilizer. However, liquid manure and the excess nutrients that it may contain must be treated prior to application to fields, to protect the environment and water courses in compliance with stringent legal requirements. GEA can supply both evaporator and decanter technology to tackle any liquid manure treatment application.
Reducing phosphate and nitrogen fractions
GEA decanters can be used to reduce phosphate and nitrogen fractions efficiently from liquid manure, by separating off up to 90% of phosphate compounds and up to 35% of nitrogen compounds, together with the solids. This protects both groundwater and surface water. The pourable solids can then be composted and used as fertilizer. The liquid phase is suitable for transportation to a silo for storage, and can be applied as a high-quality, environmentally friendly natural fertilizer as required. Mobile decanters are available for optimum flexibility.
Energy-efficient evaporation technology for concentration
GEA’s evaporator technology is ideally suited to concentrating liquid manure to reduce volume, especially on breeding farms that have very large numbers of animals. Using our evaporators, the liquid manure is concentrated to up to 30% dry solids, and this can then be dried fully in a dryer.
GEA’s evaporator and dryer technologies can both be operated entirely using waste thermal energy.
The benefits to you
- Decanter or evaporator - the right process technology for every customer
- High-quality fertilizer for environmentally-friendly application which meets the most stringent legal regulations
- Protection of both groundwater and surface water, as decanters reliably separate off up to 90% of phosphate compounds and 35% of nitrogen compounds
- Mobile decanter systems for increased flexibility
- Use of waste thermal energy means lower energy costs for evaporator and dryer
GEA further supplies equipment like jet and vacuum pumps for conveying water and manure.

Decanter Centrifuge
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...
Ejector Systems
Ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids in which a gaseous or liquid medium serves as the motive force. They are "pumps without moving parts".
Hygienic valves & components
Hygienic valves from GEA form the core component of matrix-piped process plants. Thanks to a pioneering valve concept that sets standards for its flexibility, as well as the latest control and automation functions, our valves offer manufacturers maximum product safety and process reliability. All GEA hygienic valves are designed to be efficient a...
Jet pumps
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.

All pharmaceutical freeze-drying vials are the same! Aren't they?
Whether it’s a fad or the future, 100% vial traceability is becoming an increasingly important consideration in the pharmaceutical freeze drying industry. Keeping a close eye on developments is GEA. We’re investigating possible solutions and, what’s more, we have the experience, expertise and know-how to implement them.
Alcohol-free beer: They want it all – they want less
There was a time when the phrases ‘non-alcoholic beer’ and ‘tastes good’ were seldom used together in the same sentence, particularly by consumers. But low-proof and alcohol-free beers have come a long way – many of them now refreshing drinks in their own right – thanks in no small part to technology from GEA.
Innovating patient care with aseptic spray drying
At GEA, our commitment to engineering for a better world fuels our pursuit of innovative solutions that enhance patient care and safety. One of our most promising ventures in recent years is aseptic spray drying – a technology that promises to revolutionize pharmaceutical manufacturing.
