UNSPSC 47101574: Sequencing batch reactor

A device that processes the polluted substance by implementing repeatedly for the processing like the inflow and reaction within a batch reactor, release of sludge and supernatant and sedimentation of mixed liquid.

UNSPSC 47101574 Sequencing batch reactor is a Commodity code that represents modular wastewater treatment equipment and components state and local governments procure for biological treatment at municipal facilities, though recent opportunities show the code is generating little relevant procurement activity — most recent solicitations tagged with this code involve unrelated water and wastewater infrastructure products such as drive shafts, pumps, grinders, diffusers, valve components, and chemical treatment systems that do not match the sequencing batch reactor (SBR) system scope. The few tagged opportunities reflect routine maintenance and replacement of proprietary equipment already installed at facilities rather than procurement of SBR systems themselves.

City governments and counties in Florida dominate the recent activity block, with the City of Holly Hill appearing repeatedly across sole-source notices for water treatment plant equipment (WesTech drive shafts, Xylem Flygt pump parts, Chemco lime slaking systems, and Andritz belt press components). Other issuers include Collier County (lime softening improvements, countywide chemicals), Gwinnett County in Georgia (bypass pumping services, grinder replacements, polymer procurement), and municipalities in Texas (valve replacements, chlorine dioxide generation, well projects). Geographic concentration runs through Florida and Georgia with scattered activity in Texas and Arizona. Representative recent opportunities include Collier County Procurement Services soliciting an ITB for countywide chemicals (due November 13, 2026) encompassing 29 chemical line items and approximately $4 million in historical annual spend across three water treatment facilities; Gwinnett County Department of Water Resources requesting sealed bids for the Beaver Ruin Diversion Pump Station Grinders Replacements project (due November 20, 2026); and the City of Pompano Beach requesting bids on a $11 million-plus nanofiltration facility buildout under a State Revolving Fund project (due November 2, 2026). The code's sparse alignment with actual SBR procurement signals that this particular commodity classification sees limited direct market activity among state and local buyers right now.
