GEA manure management expertise will assist livestock
farmers as they face the challenges of increasing their
profitability while protecting the environment.
Bedding savings and revenue A high percentage of solids recovery eliminates the need of purchasing and hauling bedding material. Excess solids can be sold as bedding to other farmers.
Lower storage management cost More solids removal means less of it ends up in the manure lagoon which represents savings in agitation, hauling and dredging cost. Land application efficiency
Since some phosphate is removed from the liquid manure, you have options in the way nutrients are applied.
GEA manure management and nutrient recovery expertise
Primary separation of coarse particles and fibers has been used for decades. Often the liquid effluent after separation is used back on the farm for alley cleaning or stored in a lagoon to be spread on the field. While primary separation has a minimal investment, the effectiveness of separating nutrients into the liquid fraction is quite low. Over 90% of the nutrient value remains with the liquid effluent.
Additional separation steps partition nutrients into different usable streams. Of the three major nutrients (N, P and K) present in manure, nitrogen and phosporus are often the most difficult to manage and can have the largest environmental impact. A secondary separation separation step with a GEA manure Decanter can segregate the nutrients based on the customers need.

Your manure is a valuable resource
From raw manure, to effective separation and decanter centrifuge systems, we have the process know-how to create value with your progressive manure and nutrient management practices.
Value-added solids The solids resulting from a secondary separation process contains a high level of nutrients which can serve as a valuable fertilizer.
Fertilizer-savings Using both liquid and solid fractions as fertilizer offers substantial savings when compared to commercial fertilizer costs, storage and application.
Water-savings Liquid derived from primary separation equipment can be recycled for alley flush, power flumes and sand separation. Additional solids can be removed from the liquid stream with a GEA manure Decanter.
UK government has released guidance for farmers and landowners that explains the rules they must follow if their land is in a nitrate vulnerable zone (NVZ). NVZs are areas designated as being at risk from agricultural nitrate pollution. They include about 55% of land in England. The Department for Environment, Food and Rural Affairs (Defra) reviews NVZs every 4 years to account for changes in nitrate concentrations. If land was in an NVZ for the first time in 2017, farmers have until 31 July 2019 to comply with some of these rules.
• storing slurry and poultry manure
• spreading manufactured fertilizer
• equipment you can use to spread slurry
• spreading some types of organic manure
• separating slurry
Farmers must be able to store all the slurry they produce and all poultry manure produced in a yard or building, during the storage period, unless you reduce the volume by:
• sending it off farm
• spreading some of it on fields with a low risk of runoff
In addition to storing the slurry produced, farmers must provide storage for any slurry, rainfall, washings or other liquid that enters the store during the storage period.
Why farmers should consider manure separation?
Separating manure by decanter centrifuge makes it possible to manage the solid and liquid fractions individually, with greater flexibility and efficiency.
While primary separation has a minimal investment, the effectiveness of separating nutrients into the liquid fraction is quite low. Over 90% of the nutrient value remains with the liquid. Additional separation steps partition nutrients into different usable streams. Of the three major nutrients (N, P and K) presenting manure, nitrogen and phosporus are often the most difficult to manage and can have the largest environmental impact. A secondary separation step with a manure Decanter we segregate the nutrients based on the customers need.
By removing more solids from the liquid, phosphorous and nitrogen levels are reduced giving greater leeway in the manure spreading schedule to apply the necessary nutrients at the time when the crops need them the most, getting more liquid onto the land in consent with local legislation, while maintaining balanced soil conditions.
The higher capture of solids from the liquid fraction ensures little or no settlement in storage lagoons and tanks, maintaining storage capacities and removing the requirement for regular agitation and digging out. The drier solid fraction, which is more nutrient-richer, is easier to store and cheaper to transport to nutrient deficient fields further away, as a soil conditioner it can be applied in a controlled manner. Use as green bedding is also an option under the right conditions and in compliance with legislation.
What percentage of the liquid fraction it can extract?Over 85% (>30% dm in solids, <3.5% dm in liquid)
How many cubic meters of slurry can it deal with in an hour?Range up to 80m3
What is a decanter?A decanter is a continuously operating centrifuge with a horizontal solid wall bowl, and automatically controlled scroll, developed specifically to dewater liquid manures and digestate.

Liquid manure obtained from animal husbandry is a valuable fertil-izer in modern agriculture. It must, however, be properly integrated into the natural nutrient cycle. GEA has developed a cost-effective processing concept for this demand. The aim is to process the liquid manure, to treat the associated nutrient surpluses and to takespecific advantage of the resultant products.
Separation of Nutrients N and P2O5
PROPERTIES RAW MANURE• Difference in animal species, food, maturity, etc.• N binds partly to solid (Norg) and is partially soluble (Nmin)• P2O₅ binds mostly to solids• K2O is completely soluble• Decanter removes particles down to 40 microns• Major reduction of Chemical Oxygen Demand (COD) level in liquid
