Abstract

The objective of this study was to determine if an organic media attached growth bioreactor could effectively be used as a means of odor control for swine waste. The pilot-scale attached growth bioreactor system was evaluated against a standard pit recharge system, which served as the control. Performance was based on water quality testing, odor assessments by a human sensory panel, and air phase measurements of ammonia and hydrogen sulfide. The affect of aeration on the system was also evaluated, along with various types of organic media (kenaf, hardwood mulch, and corncobs). Overall, the bioreactor systems were effective in reducing orthophosphate, COD, volatile acids, and phenol concentrations as compared to the control. The bioreactor systems were not effective in reducing the conductivity, ammonia or total solids concentration of the wastewater. With the exception of the corncob media, all bioreactor systems significantly reduced the overall odor intensity and the fecal characteristic of the wastewater as compared to the control system.
