UNSPSC 50501609: Nutritional phosphorus supplement

Mineral supplements are used to ensure that adequate amounts of nutrients are obtained on a daily basis, if optimal amounts cannot be obtained through a varied diet. Phosphorus is a component of bones, cells, in energy processing and many other functions.

UNSPSC 50501609 Nutritional phosphorus supplement (Commodity) comprises specialized equipment and integrated systems designed to remove or recover phosphorus from wastewater treatment streams, specifically through controlled chemical precipitation processes. Recent state and local solicitations under this code center on wastewater treatment facilities procuring complete phosphorus control systems—equipment bundles that include reactors, chemical feed systems, instrumentation, controls, and ancillary hardware capable of treating digested sludge to precipitate and recover phosphorus compounds while meeting nutrient-removal regulatory objectives. The issuing bodies are municipal wastewater utilities and their engineering partners, operating under federal grant funding and subject to Buy America and anti-discrimination compliance requirements.

The City of Orem, Utah, posted an RFP (PROJECTNO230904) on September 3, 2026, soliciting design, manufacture, furnishing, delivery, and technical support of a complete phosphorus control system for its Water Reclamation Facility, with proposals due October 16, 2026. The scope includes process equipment, pumps, tanks, chemical feed and storage systems, blowers, valves, instrumentation, and controls capable of treating anaerobically digested sludge through controlled struvite precipitation; the successful supplier will serve as equipment subcontractor to a General Construction Contractor and must deliver the system within six months of notice of award, with shop drawings due within sixty days. The bid is structured as a lump sum covering equipment design and fabrication, factory testing, packaging, freight, field support, commissioning, operator training, documentation, and one-year warranty, with progress payments tied to shop drawing approval (20%), delivery (60%), and project completion and testing (remainder). Evaluation prioritizes equipment quality, materials, performance, life cycle costs, manufacturer experience, and references. Questions were due October 1, 2026. This represents the primary recent activity visible under the code; no other state or local opportunities are evident in the source.
