UNSPSC 47101552 Moving bed filter (Commodity) does not reflect the activity state and local governments are actually procuring under this code. The recent opportunities in the source are dominated by water and wastewater treatment services, chemical supply, equipment parts, system upgrades, and capital construction projects—none involving moving bed filters. The code shows little relevant recent activity; the mismatch between the nominal commodity and the work being solicited suggests either miscoding by issuing bodies or a code that has drifted from current state and local procurement patterns.

The few opportunities posted under or near this code span a geographic mix including Texas, Florida, Georgia, California, and Arizona, with issuing bodies ranging from cities (Tampa, Phoenix, Huntsville, Tucson, Palm Bay) and counties (Collier, Gwinnett, Orange) to school districts (Seminole County) and water authorities. Representative recent solicitations include the City of Tampa's request for Sweco grit remover replacement parts (RFQ, June 2026); Gwinnett County's solicitation for solids dewatering and thickening polymer (sealed bid, July 2026); and the City of Phoenix's procurement for Sanitaire membrane diffusers serving wastewater aeration basins (IFB, July 2026). The bulk of procurement activity under codes in this family centers on treatment chemicals, membrane systems, bar screens, diffusers, pumps, control systems, and integrated plant upgrades rather than moving bed filters specifically. Buyers in this space include municipal water departments, county utilities, and regional treatment authorities; Gwinnett County, Collier County, and the City of Phoenix appear multiple times across the opportunities block. Activity is steady through mid-2026 with response windows typically 30–60 days. If your firm pursues contracts in water and wastewater treatment equipment and services, verify the actual commodity codes assigned to current RFPs rather than relying on this code designation.
