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.

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

201568manure and the storage time Peters et al. 2008. Different treatment processes have been developed in order to minimie the negative environmental impact related to manure management. Among these treatments solidliquid separation is one of the widely applied techniques. In fact separation techniques often represent a relatively cheap

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.
