UNSPSC 47101566: Multiple media filter

A filter that is blended two or more of filter medias like the filter sand, anthracite, zeolite, active carbon, or sand for use.

UNSPSC 47101566 Multiple media filter is a Commodity code that encompasses filtration, separation, and treatment equipment components that state and local governments procure to maintain and upgrade water and wastewater treatment infrastructure. Recent state and local solicitations under this code reflect ongoing capital and operational spending on treatment plant upgrades, membrane systems, and replacement parts for existing installed equipment—not generalized filter cartridges but rather specialized membrane diffusers, lime softening systems, polymer blending units, grinder replacement, and proprietary OEM components integrated into municipal water and wastewater networks. The issuing bodies span a diverse mix of municipal water departments, county utilities, regional treatment authorities, and school districts, with significant activity concentrated among repeat institutional buyers such as Collier County (water treatment plant improvements, lime softening), Gwinnett County (bypass pumping, polymer procurement, grinder replacement), the City of Phoenix (membrane diffusers, instrumentation), and the City of Atlanta (polymer blending units, grinder parts and services). These entities manage large-scale treatment infrastructure and operate on multi-year procurement cycles with established vendor relationships often driven by OEM compatibility and equipment replacement schedules rather than open competition.

Geographic activity clusters in Florida (Collier County, Marion County, Volusia County Holly Hill, Broward County, Orange County), Georgia (Gwinnett County, DeKalb County, Athens-Clarke County), Texas (Waxahachie, McKinney, Collin County, Bell County), and Arizona (Phoenix), with secondary activity in other states including Illinois and Pennsylvania. Representative recent opportunities include Collier County's ITB for countywide water and wastewater treatment chemicals (due November 13, 2026, 29 line items, 4-year term, estimated $4 million annually), Gwinnett County's competitive sealed bid for solids dewatering and thickening polymer (due July 30, 2026, four-year term beginning October 19, 2026), the City of Phoenix's IFB for membrane diffusers (due July 2, 2026, five-year contract, DBE-N program participation required), and the City of Waxahachie's RFP for full-service chlorine dioxide generation (due May 28, 2026, two facilities, 10-year potential term). Sole-source and single-vendor procurements appear frequently, reflecting the proprietary nature of existing installations and OEM-exclusive parts availability (Xylem Flygt pumps, Chemco lime slaking systems, Andritz separation equipment, Agora Wet Well Wizard aerators). Activity indicates sustained demand for replacement parts, system upgrades to meet regulatory compliance (PFAS, MCL), membrane technology deployment, and integrated service contracts bundling equipment supply, maintenance, and technical support over multi-year terms.
