These high pressures can result in ruptured seals, leading to manure spills. Agitation time reduced - With separated liquid, very little agitation is needed prior to removal from storage. There is some settling of suspended solids, but these par-ticles are very small and are usually easy to stir up. Other uses for solids - Especially with the mechanical separators, the solids are relatively easy to store and can be handled with conventional solid manure equipment. Sometimes, these solids have other uses.
Some farmers recycle the solids as bedding material.
Others re-feed some of the solids to livestock, while others compost and sell the solids. Gutters may be flushed regularly using this liquid. It has a greater ability to remove solids than does unseparated manure. Odor control - Farmers with separators are finding that the total level of odor from the solid and liquid manure storages is less than the level of odor would have been with no separation. To some farmers, this would be one of the most expensive parts of the manure system and it may be hard to justify the purchase.
