A Practical approach to odor control/air purification
Note:In Public Works -- Vol. 129 - no. 2 (February 1998).
Summary:Effective odor control and air purification requires that the odor or impurities be contained in either a ventilation stream or confined space. The odors and impurities can then be selectively treated. The traditional approach to elimination of the offending odor and toxic contaminants has been to scrub with nonselective chemicals or masking substances.
