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 (Commodity) covers the supply, maintenance, and rehabilitation of reverse osmosis, deionized water, and related water treatment systems that state and local governments procure for laboratory compliance, municipal potable-water production, and facility operations. State and local buyers under this code include higher-education institutions, county utilities and environmental agencies, municipal water treatment authorities, and specialized facilities requiring certified Type I water for analytical testing. Recent solicitations show a mix of maintenance-and-service contracts for installed systems, full-system rehabilitation projects with equipment replacement, and parts-and-service supply agreements. Texas State University is requesting reverse osmosis and deionized water system maintenance and ongoing support services through an RFP due August 10, 2026, while Hillsborough County, Florida, is pursuing sole-source maintenance on MBR-series deionizer units through Thomas Water Purification LLC with an estimated two-year contract value of $76,530. Collier County, Florida, is issuing a sealed-bid IFB for comprehensive rehabilitation of four reverse osmosis treatment trains at its North County Regional Water Treatment Plant, including replacement of 252 new pressure vessels, 1,512 RO elements, and control system upgrades, with a $4 million estimated project budget and a May 1, 2026, bid deadline. These contracts reflect the practical focus on equipment replacement and system maintenance rather than raw ultrafiltration-equipment procurement alone.

Solicitation activity concentrates in Texas and Florida, with secondary activity in Arizona, Oregon, Connecticut, and Minnesota-coordinated multi-state cooperative purchasing. Collier County's $4 million RO skid rehabilitation project represents the largest recent opportunity, requiring original-equipment-manufacturer status, municipal project experience, and Allen-Bradley and iFix SCADA system expertise. The Oregon Health Authority's RFP 6225 for reverse osmosis point-of-use water treatment installation and maintenance in Morrow and Umatilla counties includes an estimated $350,000 to $500,000 per contract with preferred vendors already selected as of March 2026. Smaller municipal and county utilities in Arizona—the City of Goodyear's digester rehabilitation solicitations—show ongoing asset-life extension and operational-reliability work. The code shows no standout single repeat buyer across the recent opportunities; activity appears distributed across independent utilities and facility managers rather than concentrated among a few large jurisdictions.
