The separation of manure solids from the liquid emulsion matrix is a necessary step in any advanced treatment of manure from confined animal feeding operations. The separation of solids can reduce storage requirements, provide a usable co-product for sale such as compost or bedding, and significantly reduce odor potential. Primary separation has become an accepted practice on large animal facilities however, the addition of secondary separation, specifically mechanical methods, is not common for achieving nutrient management goals. Secondary separation focuses on the residual solids in the particle sizes ranging between those separated during primary separation and suspended solids. Finally, maximizing mechanical separation will reduce the costs of any further treatment method specifically through chemical coagulation or oxidation for the capture of phosphorus. In this system, separation is achieved by first removing the manure solids which can be retained on screens and then focusing on particles which may be too small to be retained on screens but have weight. The described system is in-place and operational since November of 2004 on a 650 head dairy in New York State. This new system represents an advancement in technology from the system which was in-place and operational for the four previous years. The new system includes press screw separation and a centrifuge. Additional data on the chemical capture of phosphorus will be included as testing is completed.
