The SanScent Air Scrubber (Innoventor Engineering Developments, LTD Leslie, MO.) was tested on a swine nursery for its ability to remove particulate matter (PM), ammonia (NH3), and hydrogen sulfide (H2S) from the exhaust air stream. Two scrubbers (one on an 18-in diameter and one on a 24-in diameter exhaust fan) were instrumented and tested. Data collection occurred over a 4-hour period for each test. Results indicate that the reduction in airflow through the fans due to the addition of the scrubbers was approximately 7% on the 18-in diameter fan and 10% on the 24-inch diameter fan. Contaminant levels in the exhaust air prior to the scrubbers were low (<0.5 mg/m3 PM, <5ppm NH3, <1 ppm H2S). Under these conditions, there were no statistically significant differences between contaminant levels pre- and post-scrubber. The particulate matter removal efficiency was measured at 36% for the scrubber on the 18-in diameter fan and 61% for the scrubber on the 24-in diameter fan. Cost to install and operate the scrubbers for a typical finishing operation in Virginia was estimated at $0.66/pig produced, not counting the cost to handle the additional waste water.
