UNSPSC 47101552: Moving bed filter

A device that scratches out the sand filtered surface attached with the suspended solid in the waste water and it is supplied to the lower part of the filtering layer continuously after washing, or new sand is sent to the filter layer in proportion from the top. There is a method to take out the polluted sand that includes the floating substance to downside while sending new sand from the top.

UNSPSC 47101552 Moving bed filter is a Commodity-tier code, and recent state and local solicitations under it show minimal activity directly aligned with the code's nominal scope. The few opportunities posted reference moving bed filtration equipment tangentially—most involve proprietary equipment replacement, parts supply, and maintenance for water and wastewater treatment infrastructure rather than procurement of standalone moving bed filter units. The issuing bodies are primarily Florida municipalities (City of Holly Hill, Collier County), Georgia counties (Gwinnett County, Marion County), and Texas cities (Waxahachie, Phoenix), with activity spanning water treatment plant upgrades, wastewater reclamation, and chemical feed system improvements. Representative recent solicitations include the City of Holly Hill's sole-source notice for Chemco Systems lime slaking systems (Posted Oct 19, 2026; 26PWSS10), Collier County's ITB for countywide chemicals serving water and wastewater treatment facilities (Posted Oct 13, 2026; response due Nov 13, 2026), and the City of Phoenix's IFB for membrane diffusers (Posted Sep 29, 2026; response due Jul 2, 2026). Geographic activity concentrates in Florida, Georgia, and Texas, with scattered notices in Arizona and Nevada.

The code does not report concentrated recent procurement volume. Instead, state and local agencies issue frequent sole-source notices for OEM-specific replacement equipment (Xylem Flygt pumps, Andritz separators, WesTech drive shafts, Chemco lime systems) and recurring ITBs and RFPs for specialized chemical treatment, parts supply, and maintenance contracts that reference water treatment plant operations. No RFP, RFQ, IFB, or ITB in the source material explicitly names "moving bed filter" as a discrete deliverable; opportunities tagged with this code typically address broader equipment classes—grinders, aeration systems, valve exercisers, polymer blending units, and instrumentation—or downstream services like bypass pumping and SCADA integration. The code shows little current relevance to mainstream state and local water and wastewater procurement in the most recent opportunity block.
