Diversion From Land Disposal Of Nutrients Recovered From Non-MPP Processing Plant Wastewater To Value-Added Use In Multi-Species Feed ...

Non-Meat and Poultry Product (Non-MPP) food processing plants manage their effluent to satisfy environmental regulations concerning waste discharge. Currently, many non-MPP plants mechanically screen out large pieces of organic material (biosolids) that are processed for use as livestock feed. However, minute biosolids in liquid suspension collected from the food plants effluent are generally disposed of by land application or by land filling due to contamination by chemicals used to flocculate the biosolids out of the wastewater. APS will test the feasibility of using PFC, a new flocculation compound, across a broad spectrum of non-MPP processing industry segments to recover from non-MPP plant wastewater unadulterated digestible nutrients useable as livestock feed. This projects objectives are to 1) estimate the optimum injection rate of PFC, 2) estimate and prioritize the nutritional and economic value of reclaimed biosolids, and 3) estimate the variable cost impact of utilizing PFC versus the current wastewater treatment program in use at numerous non-MPP plants. A significant portion of non-MPP operations are expected to show the potential for gaining a significant economic and environmental benefit by utilizing PFC in their effluent treatment systems while also establishing a new and relatively inexpensive feed source to livestock producers.
