Assessment of LWR's manure treatment system with in-sequence solid separation and membrane filtration of liquid hog manure:

Project: MLMMI 2009-07

Objective

The objective of this project is to sample and analyze inputs and outputs from Livestock Water Recycling (LWR) company's manure treatment system, which is used to separate plant nutrients and pathogens from liquid hog manure. The analyses of the inputs and outputs will be used to assess the efficiency of LWR's manure treatment at removing both nutrients and pathogens from manure. In addition, this project will determine if nutrients concentrated by the system are lost by volatilization or other means.

Keywords: manure treatment, phosphorus, nitrogen, nitrogen concentration, membrane filtration, manure solid separation, wastewater treatment, livestock water recycling, nutrient budget, livestock waste, manure pathogens.

Summary

Note to Reader concerning Phosphorous Redistribution Projects

In order to comply with current provincial manure management regulations, livestock producers in phosphorus surplus areas of Manitoba have to implement ways to redistribute nutrients to phosphorus deficient areas. The Manitoba Livestock Manure Management Initiative (MLMMI) is undertaking a series of projects to find effective affordable solutions for producers. This report is one of these projects.

All options available to producers in phosphorus surplus areas are under consideration. These include but are not limited to manure separation, manure handling and storage, and liquid manure transportation. This report is only one of many options that are under consideration.

This project evaluated the Livestock Water Recycling (LWR) manure treatment system at a commercial finishing barn in Manitoba. The project demonstrated that phosphorus removal greater than 95% can be achieved using LWR's proposed, patented, configuration of mechanical and chemical processes but at very high operational costs.

Complete project details are in the attached report.
