Odor Control for Animal Housing Systems with Liquid Manure - Barriers

Following the concept that odor is transmitted on dust particles, an alternative to filtering particles during air movement is to stop the movement altogether. Windbreak walls or air dams have proven effective in reducing both downwind dust particle concentrations and odor concentrations. Windbreak walls have been constructed with 10-foot x 10-foot pipe frames and tarpaulins, and placed a the end of swine-finishing buildings, immediately downwind of the exhaust fans. Downwind dust and odor concentrations were reduced on demonstration facilities, in area with windbreak walls, due to plume deflection. Depending on the materials used for the barriers (tarpaulins on a frame or solid wood, for example) barrier life can be from a few years to decades before replacement is needed.
