Efficient processing of liquid manure

The mobile container system for liquid manure separation

From waste product to recyclable material: Liquid manure can be processed efficiently and cost-effectively with the MoRoPlant20 mobile container solution. The heart of the plant is the decanter from Flottweg. This enables farmers to achieve particularly high separation efficiencies for phosphate and nitrogen.

Livestock farmers, agricultural consortia and farm outfitters are looking for new economical and environmentally friendly ways to process pig and cattle manure. Above all, the high phosphate and nitrogen content in liquid manure is critical for its storage, transport and further processing.

The MoRoPlant separation system offers a simple and efficient solution: It separates liquid manure into solids and process water even before storage. The dry solids extracted can even be sold as garden or spreading fertilizer.

Users who are interested in the separation system also benefit from Flottweg's comprehensive advice and service. For example, it is possible to obtain an individually tailored test system to determine specific separation efficiencies and to test the functionality of MoRoPlant in your own facilities.

Liquid manure processing

The MoRoPlant compact plant for an efficient dewatering of liquid manure. From liquid manure to natural fertilizer and process water.

How MoRoPlant works

The energy-saving compact plant is located in a container and can be used in different locations. Before the separation process, a special flocculant consisting of bentonite and starch is added to the liquid manure. The separation takes place in a Z-series modular high-performance decanter from Flottweg. Through the combination of flocculant and high-performance decanter, the separation system achieves a dry solids content of over 30 percent.

A special feature is the highly efficient separation of phosphate: up to 99 percent phosphate is bound in the solids. For nitrogen, the liquid manure separation rates are over 60 percent (dairy cattle) and over 40 percent (pig) respectively. The German Agricultural Society has awarded the "DLG recognized" test seal in gold affirming the high degree of selectivity.

Liquid manure separation in detail

Due to its high centrifugal acceleration (approx. 2,500-5,000 rpm), the decanter efficiently separates the solids in the liquid manure from the liquid phase.

Because the suspended particles have a higher density, they collect on the bowl wall. The scroll conveyor transports the solids continuously to the discharge. The liquid phase flows off as process water along the scroll.

The excellent separation results of MoRoPlant20 have been confirmed by the German Agricultural Society in an extensive field trial. For these results, the separation system received the ""DLG recognized"" test seal in gold.

The measurements took place on a pig farm in Bavaria. The trials were carried out with liquid manure from pig herds and dairy cattle herds, from six separate operations. The separation efficiency for dry solids was more than 80 percent. Nitrogen separation was respectively more than 40 percent (pig liquid manure) or 60 percent (dairy cattle liquid manure). Extremely high phosphate separation rates of over 90 percent were achieved.

The features of our decanter centrifuge

decanter-bowl

Decanter bowl

The decanter centrifuge bowl has a cylindrical-conical shape and rotates at a high speed. Its geometry is precisely matched to the liquid manure/additive mixture.

To the decanter bowl
decanter-scroll

Decanter scroll

The scroll rotates at a low differential speed relative to the bowl and conveys the settled solids in the direction of the conically narrowed bowl end. The differential speed determines the residence time of the solids in the bowl. Among other things, this residence time is decisive for a high dry solids content after separation.

About the decanter scroll
decanter-overflow-weir

Overflow weir

The clarified process water flows to the cylindrical end of the bowl and is discharged through openings in the bowl cover. These openings contain precisely adjustable weir plates with which the depth of the pond in the bowl can be adjusted.

About overflow weir
decanter-materials

Adjustable impeller

As an alternative to the overflow weir, the process water can also be discharged from the bowl under pressure via an impeller in a closed system. This saves an otherwise necessary feed pump.
