UNSPSC 47101608: Flocculents

UNSPSC 47101608 Flocculants is a Commodity code. State and local governments buy flocculant polymers, dewatering chemicals, and related treatment agents under this code to condition biosolids, thicken sludge, and improve solids separation in water and wastewater treatment operations. Recent solicitations show municipalities procuring liquid emulsion polymers for centrifuge and belt-filter dewatering, cationic dewatering polymer for wastewater treatment plants, and polymer blends for rotary drum thickeners—all critical to biosolids handling and disposal. The code encompasses both pre-approved products and alternate formulations subject to bench-scale and full-scale performance testing before award.

Water and sewer districts dominate the issuing-body mix, with municipal water authorities, county water-and-sewerage systems, and municipal wastewater treatment plant operators soliciting regularly. Collier County (Florida), Gwinnett County (Georgia), Waco (Texas), Cartersville (Georgia), and the Macon Water Authority have posted multiple opportunities under this code in recent months. Geographic activity concentrates in Florida, Georgia, and Texas, with secondary activity in Oregon, Connecticut, and California. Representative recent opportunities include Gwinnett County's solicitation for solids dewatering and thickening polymer (ITB, bids due July 30, 2026), awarding on lowest cost per dry ton of sludge dewatered with a four-year initial term and optional renewals; the City of DeLand's bid for flocculant polymers for rotary drum thickeners and biosolids centrifuges (ITB B-26-18, bids due September 15, 2026, using Polydyne SE 2157 and SE 2199 as baseline products); and Collier County's countywide chemicals bid (ITB 268705, bids due November 13, 2026) spanning 29 chemical line items including polymers, with historical annual spending of approximately $4 million across water, wastewater, and parks facilities. Pre-approval of products and mandatory performance testing are standard conditions; vendors often must submit samples for evaluation at least two to three weeks before bid opening.
