UNSPSC 47101550: Compression filter

A type of equipment that is to filter the discharged water by penetrating the filter water by applying the water pressure by closing the filtering device.

UNSPSC 47101550 Compression filter is a Commodity code that covers replacement filter media and filter cartridges used in water treatment, wastewater treatment, and industrial fluid-conditioning applications. State and local governments procure compression filters primarily as components within larger treatment system maintenance contracts rather than as standalone line items. Recent solicitations show the code appearing tangentially in water and wastewater treatment infrastructure projects where filtration is a subordinate element of design-build work, equipment upgrades, or parts procurement — such as Texas State University's reverse osmosis and deionized water systems maintenance, the City of Waxahachie's chlorine dioxide generation program, and Collier County's water treatment facility improvements. The code surfaces most frequently in state and local opportunities where treatment plants are upgrading or replacing systems that incorporate filtration stages.

Issuing bodies span water utilities (Texas State University, City of Waxahachie, Collier County, Georgia water authorities including Gwinnett County and City of Calhoun), municipalities (City of Phoenix, City of Tampa, cities in Florida and Georgia), counties (Orange County Florida, Collier County, Gwinnett County, Columbia County Georgia), and special districts (Eastern Municipal Water District in California, transit and water reclamation authorities). Gwinnett County, Georgia and Collier County, Florida appear multiple times as repeat buyers of water treatment parts and services. The mix of solicitations shows water quality improvement is a persistent driver — many recent opportunities emphasize PFAS reduction, membrane filtration, reverse osmosis pretreatment, and advanced oxidation, placing compression filter components within broader capital improvement and design-build procurement cycles. Representative recent solicitations include the City of Calhoun's CMAR delivery for PFAS reduction treatment plant upgrades (due July 30, 2026, RFP), the City of Waxahachie's full-service chlorine dioxide generation program with sodium chlorite chemical supply (due May 28, 2026, RFP), and the City of Phoenix's membrane diffuser procurement (due July 2, 2026, IFB) — all of which involve filtration or treatment chemistry where compression filter media would be a supporting consumable. Geographic activity concentrates in Texas, Florida, Georgia, and California, with secondary activity across Arizona, Colorado, and the Pacific Northwest.
