NRCS developed a new technical document entitled “Solid-Liquid Separation Alternatives for Manure Handling and Treatment.” This document brings together both the theory behind solid-liquid separation and the practical application of many different separation technologies. Several farm-scale demonstration projects are also summarized in the report. Solid-liquid separation can serve to achieve many livestock operational objectives such as nutrient partitioning, improved pumping characteristics, solids removal from storage facilities, and reduced organic loadings. The use of separation technologies is essential for many operations and has become an integral part of the efficient performance of these livestock facilities. Some of the purposes and uses of this document include assisting in solid-liquid separation technology selection, evaluating separation performance, and quantifying the impact of solid-liquid separation on manure management. The document also includes information on the uses and benefits of coagulants and flocculants and separation methods associated with sand-laden manure.
