Manure odor bio filters topic of ISU conference

FARM BROLL

AMES, Iowa (AP) — The latest technology designed to reduce the odor from hog manure will be the focus of a conference next month at Iowa State University.

The Bio-filter Conference on Aug. 20 is held for producers and managers of animal feeding operations and others interested in learning about development of the latest equipment.

ISU agricultural and bio-systems engineering professor, Steve Hoff says bio filters can be an effective means to reduce odor and other gas emissions from ventilated animal and manure storage facilities. He says the conference will outline costs, effectiveness, management and other details, and provide sources of science-based information on bio filters.

A demonstration of a bio filter operation with an Iowa State bio filter mobile unit is planned.
