BIOFILTERS FOR POINT-SOURCE GASEOUS EMISSIONS FROM DAIRIES
Oliver, Jason; Gooch, Curt
Point-source gaseous emissions from dairies contain complex mixtures of contaminants in ranging concentrations emitted at various flow rates. While most air pollution control technologies have optimal application limits, biotechnologies like biofilters, which use diverse microbial communities to mitigate contaminants, are adaptable to a broad range of effluents. Biofilters are also relatively low-cost, simple in design and control, can be constructed by farm personnel from affordable, readily-available materials, and have small energy requirements, furthering their suitability for dairies.
