UNSPSC 41104921: Laboratory membrane filters

UNSPSC 41104921 Laboratory membrane filters is a Commodity code encompassing membrane elements and filtration components used in municipal water treatment, wastewater recycling, and potable water systems. State and local governments procure reverse osmosis (RO) membranes, microfiltration (MF) membranes, and associated spare parts—including pressure vessels, interconnectors, end-cap adapters, and O-rings—for rehabilitation and replacement of existing treatment trains at regional water recycling facilities and treatment plants. The issuing bodies are primarily water and wastewater utility districts and municipal water authorities; school districts also appear occasionally. West Basin Municipal Water District in California has solicited multiple times under this code in recent months, indicating a repeat buyer with ongoing membrane replacement and system rehabilitation needs.

Recent opportunities span California and Florida. West Basin Municipal Water District issued RFQ RFQTH0131 on June 25, 2026, for submerged microfiltration membranes as direct replacements for existing Scinor PVDF and Memcor modules at the Edward C. Little Water Recycling Facility, with SOQs due May 26, 2026, and a subsequent IFQ for 852 RO membrane elements (8 x 40 inches) and spare parts for the Juanita Millender-McDonald Carson facility, with quotations due February 26, 2026. Collier County issued IFB 26-8646 on April 23, 2026, for comprehensive rehabilitation of four RO treatment trains at the North County Regional Water Treatment Plant in Naples, Florida, involving removal and replacement of 252 pressure vessels, 1,512 RO elements, and associated mechanical and control components, with a sealed bid deadline of April 24, 2026, at 3:00 p.m., and an anticipated project budget of $4,000,000. Forsyth County Schools in Georgia posted a brief RFQ (P2609) on June 22, 2026, for ERU filters with proposals due July 7, 2026, though scope details were sparse. West Basin applicants must demonstrate NSF-60 and NSF-419 certifications and three years of municipal experience; Collier County bidders must hold OEM status for membrane systems with minimum 3,000,000 gallons per day capacity. West Basin's Small and Local Business Enterprise Program offers a 3% evaluation credit for SBEs or LBEs as prime contractors, or 6% if both designations apply.
