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, a Commodity code, does not align with the scope of work actually being solicited by state and local governments under this code. The recent opportunities in the source block reference water treatment equipment, facility maintenance, chemical services, and infrastructure construction — including reverse osmosis systems, chilled water loops, polymer blending units, grit removal, bar screens, and lime softening improvements — but none involve sequencing batch reactors as discrete products or services. A sequencing batch reactor is a specialized wastewater treatment technology (activated sludge variant using batch processing cycles), yet the tagged opportunities span general water chemistry, pump maintenance, SCADA upgrades, construction of treatment facilities, and equipment parts procurement without clear connection to SBR systems specifically. The code shows little relevant recent activity; issuing bodies across Florida, Georgia, Texas, California, and Arizona are buying water and wastewater infrastructure work, but the mismatch between the nominal code scope and actual procurement intent suggests either miscoding on the source side or that SBRs are not a material procurement category in the state and local market at this time.

The recent opportunities reflect fragmented buying across multiple issuer types — water utilities, municipalities, counties, regional water authorities, and school districts — with no concentration among repeat buyers for this particular code. Procurement vehicles include traditional IFB, RFP, and RFQ processes, as well as sole-source awards for proprietary equipment and specialized maintenance. Work spans routine parts and chemical replenishment (Gwinnett County polymer procurement, City of Tampa membrane sensors), multi-million-dollar facility upgrades (Orange County's $11 million ground storage tank project, Collier County's $3.2 million screen replacement), and design-build contracts for new treatment capacity (City of Sanford's $48.5 million PFAS removal plant). Evaluation tends to emphasize experience, references, technical capability, and cost, with prevailing wage and bonding requirements common on larger construction efforts. Set-asides and preferences appear inconsistently; some solicitations reference SBE or WMBE scoring, while others carry no designations.
