UNSPSC 47101563: Wastewater coalescer

A type of device that separates in accordance with the specific gravity difference by assembling of finite oil particle blended in the emulsion condition in the waste water by consecutively condensed to submerge or emerge.

UNSPSC 47101563 Wastewater coalescer, a Commodity code, covers proprietary wastewater and water treatment equipment parts, replacement components, and associated installation or maintenance services that state and local water and wastewater utilities procure to maintain operational continuity at treatment facilities. Recent state and local solicitations frame the code narrowly around original equipment manufacturer (OEM) parts, drive shafts, grinder units, membrane diffusers, polymer blending systems, and specialized equipment requiring manufacturer authorization or technical certification—not coalescers per se, but a broader family of treatment infrastructure components. The issuing bodies span county water departments, municipal water utilities, and specialized transit or facility authorities, with repeat activity from Collier County and Gwinnett County in Florida and Georgia respectively. The code sees significant activity across Florida, Georgia, and Texas, with additional procurement in Connecticut, Maryland, and California; Collier County and Gwinnett County appear multiple times as regular buyers of equipment replacements and maintenance services.

Representative recent opportunities include the City of Holly Hill, Florida's sole-source procurement (SS202001, notice October 19, 2026) for a WesTech DS43 Dual Shaft Drive replacement at its Water Treatment Plant—a $113,067 IFB-equivalent sole-source acquisition closed in September 2020—and Collier County's bid (26-8683R, notice August 20, 2026, due September 21, 2026) for $4.27 million in construction of lime softening improvements and a blend tank at the South County Regional Water Treatment Plant, an ITB requiring sealed bids and substantial completion within 277 calendar days. Gwinnett County issued multiple bids for grinder replacements, polymer supply contracts, and bypass pumping services (BL152-26, BL117-26, BL145-26) in September and October 2026. The City of Phoenix solicited five-year membrane diffuser contracts (IFB-26-0382, September 29, 2026) and pressure and temperature instrumentation (IFB-26-0398, August 18, 2026), both with DBE-Neutral participation tracking. These opportunities cluster in the water and wastewater treatment space where asset-specific, locked-in equipment choices and proprietary component availability drive frequent sole-source or manufacturer-restricted procurements at contract values typically ranging from under $100,000 for parts to several million dollars for facility improvements.
