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. State and local governments buy under this code water treatment system components and replacement parts — membrane diffusers, polymer blending equipment, hose pumps, grit removers, and related filtration and screening assemblies used in municipal drinking water and wastewater treatment plants. Recent solicitations show procurement of fine bubble disc diffusers for aeration basins, replacement parts for existing polymer blending units and specialized pumps, membrane sensors for analyzer systems, and compactor-washer screening assemblies at treatment facilities.

Issuing bodies range across state departments (Oregon Military Department), counties (Collier County, Orange County, Gwinnett County, Effingham County, Columbia County), cities (Tampa, Phoenix, Waxahachie, Winter Park, Holly Hill, Calhoun), school districts (Seminole County, Frisco ISD), regional authorities (Tampa Bay Water), and special-purpose districts (Eastern Municipal Water District, EMWD). Repeat buyers include Gwinnett County and Collier County, each appearing multiple times across treatment plant upgrades and component replacements. Recent opportunities span the Southeast (Florida, Georgia, Texas), Southwest (Arizona, California), and Pacific Northwest (Oregon). Representative solicitations include the City of Phoenix's Sanitaire membrane diffuser replacement for wastewater treatment plants (IFB-26-0382, due July 2, 2026), Collier County's South County Regional Water Treatment Plant equipment and system rehabilitation (sealed bid 26-8683, due July 15, 2026), and Gwinnett County's annual contracts for solids dewatering polymer (PE77023NONST2027000000655, due July 30, 2026) and bypass pumping services with equipment provisions (PE77023NONST2026000000647, due July 10, 2026). Treatment technology upgrades and component-level replacements dominate the code's activity — signaling sustained investment in water quality compliance, aging infrastructure rehabilitation, and system modernization across municipal water systems nationwide.
