Treatment
Treatment gives efficient volume management, rationalises sand laden handling and controls the impact of phosphorus. It makes spreading as fertilizer easier, lowers transport costs and reduces storage odour.
Conditioning and separation
Manure goes in; solids and liquids come out. A simple principle, yet the benefits are highly significant.
On the one hand you get recycled solid matter in the form of organics and on the other an enhanced concentration of nutrients in the liquid part, which is readily pumped and easy to transport. Liquid occupies a smaller volume, thus increasing existing storage capacity. Solids are easily stackable and remain stable when stored. They can be used for further treatment in composting and bedding recovery.
Separating solids from liquids also gives you less odour, lower nitrogen loss and also lower greenhouse gas emissions.
System approach for sand laden manure
A loose housing barn with sand laden manure could have an alley scraper system with a cross channel scraper leading to a reception pit with a sand liquid pump and a manure separator with the remaining effluent going to a lagoon. Note that all components are specialised in handling sand laden manure and work together to bring about significant advantages.
By separating sand from the organics, it is possible to manage the use of manure as a fertilizer without spreading sand on the fields. This means reduced wear on spreading equipment. It is also possible to reuse the liquid in a flush system.
