UNSPSC 47101553: Fiber filter

A device that uses the handle-shape textile as the filter media to arrest the pollutant substance to the air gap of the textile tissue to make the filtered water clearly purified and the arrested pollutant substance is released to the outside when washing reversely.

UNSPSC 47101553 Fiber filter (Commodity) encompasses replacement components and treatment media used in municipal and regional water and wastewater treatment systems, where state and local buyers deploy these filters across preliminary treatment, secondary processing, and disinfection stages. Recent solicitations show fiber-filter activity embedded within larger water treatment service and equipment contracts rather than as standalone commodity procurements; the code captures consumable media replacements, membrane diffuser housings, filter vessels, and related internals specified in treatment plant upgrades and ongoing maintenance agreements across public water utilities, regional treatment authorities, and special districts.

State and local water agencies—including departments of water resources, regional water treatment authorities, city water departments, and county utilities—drive procurement across dozens of jurisdictions, with concentrated activity in Texas, Florida, Georgia, and California. Texas State University, Collin College, the City of Waxahachie, the City of Phoenix Water Services Department, Gwinnett County Department of Water Resources, Collier County, the City of Atlanta Department of Watershed Management, and the Eastern Municipal Water District appear as repeat buyers. Representative solicitations include Texas State University's RFP for reverse osmosis and deionized water systems maintenance and services (due August 10, 2026), the City of Phoenix's IFB for Sanitaire membrane diffusers and fine bubble disc diffusers for 23rd Avenue and 91st Avenue wastewater treatment plants (due July 2, 2026), Gwinnett County's competitive sealed bid for solids dewatering and thickening polymer on an annual contract for the Department of Water Resources (due July 30, 2026), and the City of Waxahachie's RFP for full-service chlorine dioxide generation with sodium chlorite chemical supply through October 1, 2026. The code also captures deeper into equipment replacement cycles—Collier County's sole source notice for New York Blower odor control systems (through September 30, 2029) and the Eastern Municipal Water District's on-call construction services RFQ for underground piping and facilities mechanical services (proposal due March 27, 2026) illustrate how filter and treatment-media work threads through larger capital and maintenance contracts. Fiber-filter activity is strongest in the Southeast and Southwest, with secondary activity across California water districts and Texas municipal systems.
