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 manure Decanters efficiently reduce phosphate and nitrogen levels in liquid manure by separating up to 90% of phosphate and 35% of nitrogen compounds along with solids, protecting both groundwater and surface water. The separated, pourable solids are ideal for composting and can be repurposed as fertilizer. The remaining liquid phase is easy to store in a silo and can be applied as a high-quality, eco-friendly natural fertilizer when needed. For maximum flexibility, mobile decanters are also available.
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...
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.

Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
Closing the loop: key lessons for breweries from OeTTINGER
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
