SOLID-LIQUID SEPARATION OF ANIMAL MANURE FOR ODOR CONTROL AND NUTRIENT MANAGEMENT

Abstract

Solid-liquid separation can be an effective manure treatment method for producing nutrient-rich organicsolids for multiple uses and potentially reducing the odor generation rate and nutrient contents in liquid manure storageand treatment units. This article discusses the characteristics of animal manure relevant to solid-liquid separation forodor control and nutrient management, reviews the basic concepts used in different separation processes, and presents thedesign and operational principles and performance data of several major types of separation equipment as compiled froman extensive literature review. Such information is very useful for agricultural and sanitary engineers and animalproducers to select solid-liquid separation equipment for animal enterprises. The needs for further research anddevelopment in the area of solid-liquid separation are identified.
