UNSPSC 47131835: Desulfurizing agent

A type of deodorant that completely adheres through chemical and physical absorption by filling in on desulfurization tower and deodorant tower to remove the hydrogen sulfide and organosulphur compound. It is also referred to as the hydrogen sulfide absorbent.

UNSPSC 47131835 Desulfurizing agent is a Commodity code under which state and local governments procure water treatment chemicals—particularly lime-based desulfurizers, calcium oxide (quicklime), hydrated lime, and lime slurry used to adjust pH, precipitate contaminants, and control sulfur compounds in municipal water and wastewater treatment. Recent solicitations show municipalities and special districts buying these products either as standalone line items in broader water treatment chemical contracts or as part of integrated lime slaking systems with OEM parts and service, alongside other treatment agents such as sodium hypochlorite, aluminum sulfate, chlorine, and acids.

Issuing bodies include city water departments and public utilities (St. Petersburg, Valdosta, Jackson, Griffin, Cartersville, Meriden), county utilities (Gwinnett County, Sarasota County), and special districts (Clean Water Services in Oregon). Florida and Georgia drive recent volume, with activity across the Southeast and Southwest (Arizona, Connecticut). The City of St. Petersburg issued IFB-26-344 closing October 29, 2026, for calcium oxide supply and delivery to its COSME Water Treatment Plant in bulk quantities averaging 25 tons per order with estimated annual consumption of 1,800 dry tons, requiring NSF compliance, 24-hour emergency contact, $1 million liability insurance, and three-year contract with two optional renewals. Clean Water Services in Oregon solicited hydrated lime delivery to three water resource recovery facilities under ITB SX3435000017996, bids due September 30, 2026, for a twelve-month contract starting November 1, 2026. The City of Cartersville Water Department sought liquid lime slurry (30% slurry, 21 annual deliveries) and other treatment chemicals under itinerary closing October 30, 2026. The City of Cocoa, though tagging sodium hypochlorite rather than desulfurizers, illustrates the competitive contracting model: ITB B2617COC closing September 23, 2026, with a 5% local preference for Brevard County contractors and contract renewal through September 30, 2031.
