UNSPSC 12163102: Deflocculant

An agent for thinning suspensions or slurries. Sometimes incorrectly called a dispersant, it is a low-molecular weight anionic polymer that neutralizes positive charges on suspended particles, particularly clays and aryl-alkyl derivatives of sulfonic acid.

UNSPSC 12163102 Deflocculant (Commodity) encompasses water treatment chemicals—specifically coagulants, flocculants, and related process aids—that state and local governments procure for municipal water and wastewater treatment operations. Recent state and local solicitations show purchasing focused on sodium bisulfite, liquid ammonium sulfate, magnesium hydroxide slurry, emulsified polymers for sludge dewatering, corrosion inhibitors, and multichemical line-item contracts covering aluminum sulfate, sodium hydroxide, calcium hypochlorite, sodium hypochlorite, and related drinking-water and wastewater-treatment compounds. Issuing bodies include municipal water and wastewater utilities—the City of Meriden (Connecticut), City of Temple (Texas), City of Austin (Texas), City of Tallahassee (Florida), City of Griffin (Georgia), City of Phoenix (Arizona), Volusia County Water Resources & Utilities (Florida), City of Flowery Branch (Georgia), and Tohopekaliga Water Authority (Florida)—reflecting procurement across small, medium, and large jurisdictions. Contracts typically run one to five years with optional renewal periods, require NSF Standard 60 or AWWA certification, specify firm unit pricing for initial contract years with limited post-award escalation, and mandate delivery within 48 hours to five business days of order placement. Awards are made on lowest responsive and responsible bidder or best value basis, with some jurisdictions applying local vendor preferences and payment terms of 30 days net.
