Evaluation of manure treatment technology during Manitoba winter conditions

Project: MLMMI 2011-04


To evaluate manure separation technology under winter conditions. The physical properties of the influent manure in winter will change because of lower water usage and the temperature of influent manure. It is essential to evaluate the separation system under these conditions, especially with flocculants that have specific temperature ranges, to determine the sensitivity of the equipment to remove phosphorus under varying conditions.

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.

The implementation of a manure treatment system should only be considered after the phosphorus (P) content in manure has been optimized by feed strategies and crop/field management methods in areas where excess P is produced relative to the local land base. Only after all pre-treatment options have been exhausted, should a manure treatment system be considered. The cost and operating implications should be closely evaluated. Consideration should be given to manure transportation as an alternative to manure treatment.
