Dairy farmer produces green bedding from cow manure - Trident Bedding Recovery System

This footage is a few years old and doesn't show the most recent equipment generation, but it's still a helpful step-by-step walkthrough of Trident's bedding recovery process for dairy farms. After the dairy manure is collected (scrape manure or flush manure) it undergoes a conditioning and separation treatment in the Trident Rotary Screen Conditioner. Rinsing the manure helps clean the fibrous material. This conditioning step is critical for the quality of the final bedding product. Next, the treatment focuses on capturing specifically the large fiber. This is ensured with adequate screen opening sizes that help classify the material and only allow the large fiber to be separated from the manure. In the next step the concentrated fiber is fed into a screw press for a dewatering step. The dry and clean fiber (approximately 35% dry matter) is then conveyed to storage and available for reuse as quality bedding material in the barn, without requiring additional treatment.

More basic manure separation practices squeeze the manure or separate only a small portion of the water (e.g. roller press or slope screens), with the result that most of the original manure characteristics remain. In fact, if this material is put back in the stalls and gets wet, it very much behaves like manure again, with consequences for cow comfort and health. Trident's treatment process returns a truly manufactured bedding product. Its performance in terms of draining ability, micro climate regulation, resting surface or the reduced risk of particles adhering to a cow's skin or utter, is second to none.

What about other bedding materials like sand or saw dust? Well, the choice often depends on personal preference, the original barn design and local supply options. It's no secrete that sand causes challenges for the manure system downstream. And as the supply of other bedding materials may become difficult to manage, the Trident Bedding Recovery system is a proven and affordable choice that helps dairy farmers reduce their operating costs and maintain a high level of cow comfort.

The recent generation of Trident bedding systems are installed with stainless steel components, platform and automation system. The system is fully scalable for all dairy sizes and can be run 24/7. The bedding system also integrates seamlessly with Trident's secondary treatment options that process the remaining effluent (e.g. phosphorus recovery, water reclamation).
