Following the concept that odor is transmitted
on dust particles, an alternative to filtering particles from the
exhaust air is to decrease the concentration of odors downwind
by impeding their movement altogether. Windbreak wall or air dam
designs have proven effective in reducing both downwind dust particle
concentrations and odor concentration. Windbreak walls have been
constructed with 10-foot x 10-foot pipe frames and tarpaulins,
and placed at the end of swine-finishing building, immediately
downwind of the exhaust fans. Downwind dust and odor concentrations
were reduced on demonstration facilities, in areas with windbreak
walls, due to plume deflection. The material used for the barriers
(tarpaulins on a frame of solid wood, for example) determine the
barrier life, which may be from a few years to decades before replacement
is needed.
