UNSPSC 47101521: Ultrafiltration equipment

A water or wastewater treatment plant variant of membrane filtration equipment in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane.

UNSPSC 47101521 Ultrafiltration equipment, a Commodity code, shows recent state and local activity focused on water treatment system components and services—primarily reverse osmosis membrane rehabilitation, deionized and ion-exchange water system maintenance, filter media replacement, and bottled water delivery to public facilities. Water utilities, county governments, school districts, and state agencies are the main issuing bodies. The Broward Sheriff's Office in Florida has issued multiple ITBs for bottled water services to detention and administrative facilities, specifying 5-gallon containers and freestanding water dispensers with delivery logistics tied to facility operations. Collier County in Florida is conducting a substantial rehabilitation of reverse osmosis treatment trains at a regional water treatment plant, involving replacement of 252 pressure vessels, 1,512 RO membrane elements, and associated control systems, with an anticipated project budget of $4,000,000. Marion County Schools in Florida issued an RFP for water softener equipment, materials, installation, and monthly water-quality monitoring across twelve campus cafeterias. Hillsborough County in Florida is pursuing sole-source maintenance on deionized water systems valued at $76,530 over two years. The California Department of Water Resources is seeking comprehensive water treatment system services—inspection, testing, maintenance, and repair—across State Water Project facilities, with prevailing wage requirements.

Recent procurement activity clusters in Florida and California. Florida dominates with Broward Sheriff's Office appearing in multiple recent solicitations (bottled water services ITBs posted August 26 and July 15, 2026), Collier County's RO skid rehabilitation (sealed bid due May 1, 2026 at the North County Regional Water Treatment Plant), Marion County Schools' water softener RFP (proposals due June 10, 2026), and Hillsborough County's deionized water maintenance sole-source award (estimated $76,530, challenge deadline July 14, 2026). California's Department of Water Resources issued IFB #10220465 for comprehensive water treatment system services (bids due August 18, 2026). Riverside County, California posted RFQ 3962 for replacement filter media (quotes due July 31, 2026). The North Texas Municipal Water District issued a sealed-bid solicitation for a spiral-type clarifier drive with torque control (bids due July 30, 2026). Texas State University is requesting proposals for reverse osmosis and deionized water systems maintenance and services (proposals due August 10, 2026). Sourcewell, on behalf of multiple Washington and other jurisdictions, issued a cooperative-purchasing RFP for law enforcement equipment (proposals due June 16, 2026), which diverges from core water-treatment scope and shows minimal alignment with the code's nominal focus.
