Abstract

A biofilter was designed and constructed for odor abatement of the headspace above slurry in manure holding tanks at the Swine Research Unit (SRU) at the University of Kentucky Woodford County Animal Research Center. The SRU consists of separate animal facilities, covered manure storage tanks and manure handling capabilities. The main objective of the biofilter design is to substantially reduce potential odor emissions, specifically to prevent fugitive odors from offending neighbors. Additionally, the reduction and treatment of the headspace gases will improve worker safety at the facility. Criteria for the biofilter design include robust operation, constant and consistent odor abatement for still and intermittently stirred tanks, simple maintenance and operation for the farm crew, and the capability for conducting statistically meaningful biofilter research. Design considerations include: pressure drop estimates, operating airflow estimates, fan sizing and selection, airflow handling abilities, system controls, biomass temperature and moisture control, and biofilter sizing and layout. Preliminary studies for the design investigated pressure drop through various biomass types. Also, a characterization curve was developed for maintaining static pressure differences on the headspace of each tank. Biofilter performance monitoring is the next stage of the project.
