Separator & Screening FAQs
Separator & Screening FAQs
Slurry separating provides several benefits to farms and agricultural processes:
- Increased storage - separating slurry into solid and liquid contents allows for more compact storage, meaning less space and facilities are needed on site.
- Organic farming - separated solids and liquids from slurry can be utilised for a range of other applications, such as an organic fertiliser.
- Environmental safety - separating and storing slurry solids and liquids separately vastly reduces the risk of volatisation occurring, which can lead to leaks of harmful gases and damage to the surrounding environment.
- Green bedding - High dry matter-separated solids can be used as a source of green bedding for cattle.

A slurry separator works by pressing/squeezing the raw slurry to remove the liquid fraction. T-T's screw press separators use a double-threaded Archimedean screw and wedge wire screen for this process.
Separators can be suppled with screen sizes of 0.25mm, 0.50mm, 0.75mm and 1mm. Smaller mesh sizes allow for finer solids particles to be separated from slurry, whereas larger sizes will separate larger solids.
No - The HBC Biocell forms part of a complete system, it is designed to pasteurise the solid fraction that is discharged from a separator.
RMS (Recycled Manure Solids) can be used as a green bedding option for cattle if it conforms to DEFRA Regulations, one of which is that the slurry separator unit being used needs to produce solids of at least 34% dry matter (DM).
A standard slurry separator will achieve a max dry matter of approximately 25-30%, whereas a high dry matter version can achieve up to 30% DM plus - T-T's Dewatering Separator Range can achieve up to 38% DM solids.
Our HBC Biocell adds an additional pasteurisation step to the process that guarantees hygienic and sanitised bedding to protect your cattle from diseases.
Volatisation is the process of nitrogen decomposition within unseparated slurry whereby ammonia is released and converted into a gas or vapour. This can occur during slurry spreading (fertilisation) or storage, and if released can have negative effects on air quality and the surrounding environment.

Yes, T-T treats each application individually, providing a separator tailored to suit the needs of your site with one of four scren sizes we have available.
A standard slurry separator will achieve a maximum dry matter of approximately 25-30%, whereas a high dry matter version (green bedding version) can achieve up to 36% dm.
