ABSTRACT:
Systems and methods for treating waste water containing biological wastes such as animal waste generated in livestock-raising operations, wherein the waste water is subjected to a series of operations to separate solids from the liquid phase of the waste water and to biologically treat the waste water to break down organic components. The separated solids are stored for further treatment or conversion into useful materials. The treated liquid phase can be put to various uses. In one embodiment, the treated liquid is recycled as flush water for flushing animal waste from an animal barn, whereby little or no liquid phase escapes the system into the surrounding environment.
