The Natural Resources Conservation Service (NRCS) has 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 have 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.
On Oct. 18, 2019, a webinar provided an overview of the document including methods of solid-liquid separation, influence of manure characteristics and handling methods, fundamentals of solid-liquid separation, performance of various solid-liquid separation technologies, unique separation technologies and applications and design considerations. Those that missed the webinar can watch the archived broadcast online here.
