Abstract:
1. A method of feeding a digester manure from a flush dairy in a partially closed loop water system for circulating water downstream of the dairy for reuse of a portion of the flush water, the method comprising: flushing a dairy with flush water and delivering the contaminated flush water from the dairy to a first separator which separates the contaminated flush water into a thick fraction and a thin fraction, removing the thin fraction from the first separator to a first storage container, the first storage container comprising a sufficient diameter such that any vertical flow in the first storage container does not exceed the mean settling rate of the settleable solids contained therein, removing a thin fraction from the first storage container to be used as return flush water, removing a thick fraction from the first storage container to a downstream separator, removing a thick fraction from the downstream separator and combining this thick fraction with the thick fraction from the first separator to feed the digester, passing a thin fraction from the downstream separator to a second location.
