UNSPSC 41101902: Ion exchange apparatus

UNSPSC 41101902 Ion exchange apparatus, a Commodity code, covers the membrane and chemical systems that state and local water utilities procure to treat and recycle municipal water supplies. Recent solicitations show state and local governments buying submerged microfiltration (MF) membranes for wastewater recycling, reverse osmosis (RO) membrane elements for advanced treatment, water softening equipment and bulk salt delivery, replacement drive units for softener systems, and water treatment chemicals including activated carbon, aluminum sulfate, sodium chlorite, and ferric chloride. The issuing bodies are primarily water and wastewater agencies — municipal water districts and city water treatment departments — along with a small university utility system. West Basin Municipal Water District in California has posted at least two major pre-qualifications for membrane replacement in recent months, indicating sustained capital replacement cycles at regional recycling plants. Water treatment chemical procurement spans smaller municipalities like LaGrange, Georgia and larger regional authorities.

Activity concentrates in California and Florida, with secondary procurement in Georgia and Texas. West Basin Municipal Water District (Los Angeles County) solicited pre-qualification for submerged MF membrane replacements via RFQ RFQTH0131 (due May 26, 2026) for the Edward C. Little Water Recycling Facility and issued an Invitation for Quotation for 852 reverse osmosis membrane elements (IFQTH0119, due February 26, 2026) for the Juanita Millender-McDonald Carson Regional Water Recycling Plant. The City of LaGrange, Georgia issued an IFB for eight water and wastewater treatment chemicals (PE74150NONST2026000000025, due June 8, 2026) totaling estimated volumes of 128,000 lbs. powdered activated carbon through 254 dry tons liquid aluminum sulfate. Pinellas County, Florida solicited a comprehensive water softener repair and maintenance contract with bulk salt delivery via ITQ 230757ITQ. Successful vendors typically need NSF 60 or NSF 61 certification, demonstrated municipal experience, and capacity to meet strict delivery and support requirements; West Basin opportunities also offer Small and Local Business Enterprise evaluation incentives of 3% to 6% for certified SBEs or LBEs.
