NIGP 49348: Odor Control Equipment, Duct Mount Ozonators

NIGP 49348 Odor Control Equipment, Duct Mount Ozonators is an Item code under which state and local governments procure air treatment and odor mitigation systems for wastewater treatment facilities, lift stations, and confined spaces where hazardous or foul gases accumulate. Recent solicitations show demand for industrial-grade centrifugal blower systems that create negative pressure to capture and treat contaminated air through carbon adsorbers, chemical scrubbers, and biofilters, as well as fixed atmospheric monitoring instruments that detect hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide. Issuing bodies include municipal water and wastewater departments, county procurement divisions, and community college districts. Equipment procurement spans both standalone odor control systems and integrated atmospheric monitoring and alarm networks designed for lift stations, headworks buildings, chemical storage rooms, process basins, and underground vaults.

Recent activity is concentrated in Florida. Collier County Procurement Services Division issued a Notice of Intent to Single Source to Pero Engineering and Sales Company, Inc. for New York Blower odor control systems under a three-year contract term running October 1, 2026, through September 30, 2029, with the single-source protest deadline on April 24, 2026. The City of Phoenix Water Services Department released IFB-27-0435 on August 14, 2026, for fixed atmospheric monitoring instruments with sealed offers due September 4, 2026, specifying a five-year term with no extension options, DBE-N program participation requirements under 49 CFR Part 26, and equipment from manufacturers including ATI, De Nora, Drager, and MSA. Valencia College's District Board of Trustees posted ITB 2026-04 on September 21, 2026, for college-wide pest control services—a broader scope than the odor control systems cited above but touching equipment and facility management—with a non-exclusive three-year initial term and optional two additional one-year extensions. Contracts under this code typically mandate firm-fixed pricing, 48-hour parts availability, operator training, and compliance with EPA, FDA, and USDA approval requirements for all materials and chemical treatments.
