This project is a sequel to an odour-control technology developed by System Ecotechnologies Inc. (SEI) funded by the Manitoba Intensive Livestock Manure Management Initiative (MLMMI). It consists of a two-stage chemical treatment process which results in a significant settling of solids and elimination of odours from the untreated hog manure. The primary objective of this project was to determine the economic feasibility of application of SEI technology under various operating conditions.
