Abstract

An improved nutrient separator for separating various solid components from liquid manure includes two coaxial containers that communicate at the bottom and provide for separate extraction of the solid manure components and liquids. The phase separator includes an outer container having a partially open frusto-conical bottom and an open top and an inner container being concentric with and contained within the outer container and having an open bottom communicating with the outer container's bottom. A space is formed between the outer container's inner side walls and the inner container's outer side walls. The separator also includes means for continuously transferring liquid manure into the inner container, means for adding a flocculant material into the inner container, means for stirring the flocculant material in the liquid manure contained in the inner container, means for conditioning the liquid manure to enhance phase separation of liquids and solid manure components from the liquid manure, settling of the separated solid manure components through the inner container's bottom into the outer container's bottom and accumulating of the separated liquids in the space, means for extracting the settled solid manure components from the outer container's bottom and means for extracting the separated liquids from the space's top.
