UNSPSC 47101511: Ion exchange equipment

UNSPSC 47101511 Ion exchange equipment, a Commodity code, covers membrane filtration systems, reverse osmosis (RO) units, water softening and conditioning equipment, and spare parts that state and local water authorities procure for treatment plant operations and facility maintenance. Recent opportunities show water districts and municipalities sourcing submerged microfiltration membranes as direct replacements for existing treatment modules, RO membrane elements for recycling facilities, fixed-bed ion exchange systems for PFAS remediation, and water softener repair with bulk salt delivery—all central to regulatory compliance and treatment plant upkeep. The issuing bodies are predominantly regional water authorities and municipal water departments (West Basin Municipal Water District in California, Tampa Bay Water in Florida, City of LaGrange in Georgia, Pinellas County in Florida) alongside university facilities management (Texas Tech University). These are repeat buyers: West Basin appears multiple times across different membrane procurements, indicating ongoing capital and consumable replacement cycles.

Geographic activity concentrates in California (West Basin solicitations), Florida (Tampa Bay Water, Pinellas County, City of Holly Hill), and Georgia (City of LaGrange), with additional procurement from Texas (Texas Tech). Representative recent opportunities include West Basin's RFQ for submerged microfiltration membranes (RFQTH0131, due May 26, 2026, requiring NSF-60 and NSF-419 certifications and three years' municipal experience), West Basin's IFQ for 852 reverse osmosis membrane elements (IFQTH0119, due February 26, 2026, with liquidated damages for delays and SBE/LBE evaluation incentives up to 6%), Tampa Bay Water's RFP for PFAS ion exchange treatment design and construction services (2027001, due June 24, 2026, requiring 15+ years' ion exchange and water quality experience), and City of LaGrange's sealed bid for water treatment chemicals including coarse salt (PE74150NONST2026000000025, due June 8, 2026). The code shows steady mid-sized procurement activity driven by aging infrastructure replacement and evolving regulatory requirements.
