UNSPSC 47101605: Bacterial removal chemicals

UNSPSC 47101605 Bacterial removal chemicals (Commodity) encompasses chemical products used in water and wastewater treatment systems to control odors, reduce corrosion, remove or neutralize specific contaminants, and optimize treatment processes—including defoamers, odor-control additives, polymers, disinfectants, and treatment-system conditioning agents. State and local governments procuring under this code are primarily water and wastewater utilities, municipal water departments, and regional water authorities acquiring these products on annual or multi-year supply contracts. The issuing bodies span municipal water treatment plants, county water districts, town wastewater control facilities, and regional water resource recovery centers, with procurement activity concentrated among utilities managing treatment operations for drinking water, wastewater reclamation, and biosolids processing. Recent solicitations reflect a mix of single-chemical procurements—sodium hypochlorite, silicon dioxide defoamer, sodium bisulfite, polyaluminum chloride—and broader multi-line-item annual contracts bundling five to sixteen different treatment chemicals, often with line-item bidding allowing vendors to propose pricing on subsets of required products.

Geographic activity spans Connecticut (Town of Killingly with multiple recent chemical solicitations including defoamer, bleach, bisulfite, and polymer; City of Meriden; Norwich Public Utilities), Florida (Sarasota County, Tampa Convention Center, Collier County, City of Tallahassee, Palm Beach County, City of St. Petersburg, Hillsborough County, Indian River County), Georgia (Gwinnett County, City of LaGrange, City of Flowery Branch, City of Griffin, City of Milledgeville, City of Dublin, City of Thomson), and scattered activity in Texas, California, Michigan, and Missouri. Representative recent solicitations include the Town of Killingly, Connecticut posting multiple IFBs in June 2026 for silicon dioxide defoamer (37994, due August 3, 2026), sodium hypochlorite 12.5% bleach, sodium bisulfite, polyaluminum chloride, polymer emulsion, and sodium bioxide—all directed to the Killingly Water Pollution Control Facility; Gwinnett County, Georgia seeking annual solids dewatering and thickening polymer (PE77023NONST2027000000655, due July 30, 2026) for three regional water reclamation facilities; and the City of Flowery Branch, Georgia requesting a five-year supply contract for seven treatment chemicals including aluminum chlorohydrate, sodium hypochlorite, caustic soda, and polymer (26-007, due April 21, 2026). The code shows steady quarterly activity with procurement windows typically spanning May through August for fiscal-year contracts beginning July 1.
