201857Water quality impairment through P inputs from agricultural sources is forcing promulgation of Pbased nutrient management regulations. As a result land resources existing near animal production farms will be seriously stressed. Alternate management strategies are urgently required and chemical treatment of animal manure appears capable of providing increased options.
A solids separator is a treatment component of a manure handling system that divides an influent waste stream into low solids liquor and high solids cake. Separation efficiency . Manufacturers often state the efficiency of their equipment using the difference between influent and liquor solids concentration.
2017725The Manure Treatment Technologies Expert Panel convened in December 2014 and over subsequent months worked to evaluate the nutrient reduction benefits associated with the various categories of manure treatment technologies described in this report specifically 1. Thermochemical Conversion 2. Composting 3. Anaerobic Digestion 4. Settling 5.
Solids separation creates two manure streams a solids rich fraction that can be composted or anaerobically digested and a liquid rich fraction that is easier to pump and handle. Solids separation reduces the amount of organic material remaining in the liquid fraction thus reducing odor potential.

Manure through storage and treatment. Organic phosphorus is contained in the bodies of microorganisms in the manure. Dissolved reactive P in solution can be coagulated with metal compounds and then aggregated into clumps that will settle out by treating the manure with flocculating polymers. Solids separation
On average the recovered P precipitate solid had a concentration of 10.7 P. A second generation improved version of the technology was developed for municipal and agricultural wastewater and includes the simultaneous separation of solids and P from wastewater effluents 40 86 .
As with all treatment scenarios solids separation increases the overall cost of handling manure. The costs and benefits of solids separation must be balanced against the overall cost and potential income of production to make sound business decisions. References APHA AWWA WEF. 1998.

201856Properties of Manure Page 5 Settling of Solids Liquid Pig Manure Solids and associated nutrients in liquid pig manure settle to the bottom of storage structures relatively quickly creating variability within each structure. Thinner more dilute manure tends to be at the surface with thicker more concentrated manure at depth.

Among these treatments solidliquid separation is one of the widely applied techniques. In fact separation techniques often represent a relatively cheap
