UNSPSC 23201100: Adsorption and ion exchange

UNSPSC 23201100 Adsorption and ion exchange, a Class code, covers chemical treatment and separation equipment and materials that state and local governments procure for water treatment, industrial process applications, and environmental remediation. State and local agencies source activated carbon, ion exchange resins, molecular sieves, and related adsorbent media and systems to treat drinking water, wastewater, stormwater, and process streams. The code spans both the consumable materials themselves—replacement cartridges, bulk resin beds, granular activated carbon—and the equipment and systems that deploy them. Purchasers include state environmental and public health departments, municipal water utilities, county environmental services, and regional water authorities managing treatment infrastructure and compliance with Safe Drinking Water Act and Clean Water Act standards.

The source provided contains no recent state and local contract opportunities tagged to this code. Without posted solicitations, geographic concentration, issuing-body patterns, and near-term demand signals cannot be characterized. Firms evaluating pursuit under this code should monitor cooperative purchasing catalogs (such as state procurement alliances and regional water-authority purchasing consortia) and track RFPs and ITBs from state environmental agencies and municipal water departments directly, as opportunities in treatment-equipment categories often flow through standing agreements or project-specific solicitations rather than centralized notice boards.
