What is a slurry separator?

The principle of separating slurry is briefly explained: a slurry separator separates the solid and liquid substances from the medium to be separated. The result is separated slurry solids and thin slurry. Raw slurry usually has a dry matter content (DM content) of between 6 and 10%. Separation with a Paulmichl slurry separator can increase the DM content of the separated slurry solids to up to 32%. Our separators are also used in biogas plants to separate the solid and liquid components of the substrate.

Why separate slurry?

Separating slurry involves separating the slurry into liquid and solid substances, both of which can be utilised effectively on the farm:

The thin slurry that remains after separation is rich in fast-acting nitrogen. These nutrients are extremely valuable for fertilisation. By separating the slurry, the thin phase is absorbed more quickly into the soil and leaves less feed contamination on the field.

The solids that are separated during the separation process can either be finely spread on the field, delivered to biogas plants or used as bedding.

Mobile slurry separator from Paulmichl separates the solid and liquid substances from the medium to be separated

The versatile application possibilities of slurry separators bring many advantages to farmers, arable farmers and biogas plant operators.

Improvement of the nutrient balance and more efficient fertilisation
Slurry as a substitute for mineral fertiliser
Less feed contamination and burns due to more free-flowing thin slurry
Reduction in storage volume, application rates and transport costs
Reduction in mixing costs

Finding the right separator when it comes to separating.

When selecting a slurry separator, there are various factors to consider to ensure that the slurry separator meets the requirements of your operation. We offer various slurry separators that can be customised depending on the location, dry matter content and required throughput capacity. Our separators are suitable for agricultural plants, contract operations, biogas plants, the food industry and waste recycling plants.

The throughput capacity of the slurry separator should be matched to the slurry requirements of your farm. Depending on the medium (pig slurry, cattle slurry, biogas substrate), we use different screen baskets to achieve the optimum dry substrate content. Depending on the operational conditions, your slurry separator can be installed on mobile and stationary structures. We offer mobile slurry separators with a high throughput capacity for contract farms and inter-company applications. Our service team is always available for maintenance or problems.

Advantages Advantages

Less forage contamination and more efficient fertilisation

After slurry separation, the liquid manure is better suited for fertilisation. Due to its good flowability, it is quickly absorbed into the soil, contaminates the forage or crop less, causes fewer burns and the time window for application is larger. The liquid manure contains a high proportion of readily available ammonium nitrogen (NH4-N). The increased NH4 content accelerates the nitrogen effect. As a result, yields increase and the need for reseeding and herbicides is reduced.

Improving the nutrient balance

If the balance shows a nutrient surplus, the nutrients can be released to the outside through separation, e.g. to arable farms and biogas plants.

Optimum utilisation of solids

Due to the high proportion of organically bound nitrogen, the solid fraction can be used as a long-term fertiliser, thus returning carbon to the carbon cycle. The solid phase contains around 20% of the total N, around a third of the phosphorus and around 15% of the potash.

Reduced spreading and transport costs

Separation makes the slurry more transportable and the nutrient content per tonne is higher.

Slurry as a substitute for mineral fertiliser

After slurry separation, a higher proportion of the nitrogen in the liquid manure is in a readily available ammonium form. As a result, the nutrients penetrate the soil more quickly. This reduces ammonia losses.

Less storage capacity

Separation can reduce the storage volume by up to 20%.

Efficient and environmentally friendly spreading

The liquid manure spread develops fewer odours as it can be spread close to the ground or slit directly into the soil. In addition, the liquid manure is more homogeneous and easier to spread, which saves time and labour.

Reduction in energy costs for mixing

If the slurry is very thick, it makes the work of the agitators more difficult. An increase in electricity costs with a constant or even decreasing gas yield of a biogas plant could indicate problems with the agitators in the fermenter. In biogas plants, this can be counteracted by separating and pressing the solids out of the fermenter. The remaining liquid phase can be fed back into the tank and thus the agitators can work optimally again.

Reduction of the storage volume in the tank

By separating solids and liquids, the storage volume in the tank can be reduced considerably (depending on the source material)

Costs and subsidies

Slurry separators can be an investment, but the benefits mentioned above can pay for themselves in the long term. In some federal states, there are also subsidy programmes for the purchase of slurry separators or for biogas plants.
