UNSPSC 47101612: Polyelectrolytes

UNSPSC 47101612 Polyelectrolytes (Commodity) describes chemical additives and treatment agents that state and local water and wastewater utilities procure to condition, thicken, dewater, and clarify solids and liquids in treatment processes. Recent state and local opportunities show polyelectrolytes supplied as liquid emulsion polymers for biosolids dewatering, cationic dewatering polymers for wastewater solids processing, and flocculant polymers for rotary drum thickeners and centrifuges. The code also captures related treatment chemicals such as sodium hydroxide, aluminum sulfate, chlorine, sodium hypochlorite, and sulfur dioxide when procured as part of broader water and wastewater chemical portfolios, though some recent solicitations tagged to this code include tangential products such as liquid calcium chloride, liquid ammonium sulfate, and oxygen supply contracts that fall outside the polyelectrolyte family's core scope.

Issuing bodies include county water authorities, municipal water departments, city wastewater treatment plants, school district facilities, and regional water reclamation districts across the South, Southeast, and Southwest. The Maryland Department of the Environment, Rockland County Sewer District #1 (New York), Collier County (Florida), City of Cocoa (Florida), City of Waco (Texas), Gwinnett County (Georgia), and Clean Water Services District (Oregon) appear as repeat or recent solicitors. Representative opportunities include Rockland County Sewer District #1 issuing an RFB for solvent-based chemical degreasers for wet wells with a response date of November 12, 2026; Maryland Department of the Environment soliciting liquid emulsion polymer for biosolids dewatering with proposals due November 13, 2026 under an RFP; City of Waco posting multiple RFBs in July–August 2026 for cationic dewatering polymers, liquid aluminum sulfate, and polyaluminum chloride coagulant with response dates in August and September; and Collier County (Florida) issuing an ITB for countywide water and wastewater chemicals for treatment facilities and parks with approximately $4 million in historical annual spending and a response date of November 13, 2026. Recent activity concentrates in Florida, Georgia, Texas, and Oregon, with secondary activity across Connecticut, California, New York, and Washington state. Award basis is typically lowest responsive and responsible bidder; NSF 60 and AWWA certification are standard requirements; delivery windows commonly range from 48 to 96 hours; and pre-approval testing is often mandatory before bid submission, particularly for polymer products.
