UNSPSC 12163101: Anti sludge additives

UNSPSC 12163101 Anti sludge additives is a Commodity code that encompasses water and wastewater treatment chemicals used by municipalities for treatment plant operations, corrosion control, odor management, and sludge handling. State and local governments procure anti-sludge products and related treatment compounds primarily through municipal water and wastewater departments, with recent solicitations covering sodium bisulfite for dechlorination, magnesium hydroxide slurry for hydrogen sulfide control and corrosion prevention, liquid polymer for sludge dewatering in centrifuges and rotary drum thickeners, and blended ortho/polyphosphate corrosion inhibitors for potable water systems. Cities and counties issue these procurements as ITBs, RFPs, and RFQs with terms typically spanning one to five years, often with renewal options, and product specifications uniformly require NSF Standard 60 certification and compliance with American Water Works Association standards. The issuing bodies are predominantly medium to large municipalities and county water/wastewater utilities managing treatment plant networks, including the City of Austin, City of Phoenix, City of Tallahassee, Volusia County, Hillsborough County, and Gwinnett County; smaller cities such as Griffin, Flowery Branch, Lubbock, and Temple also solicit regularly under this code.

Recent activity concentrates in Texas, Florida, and Georgia, with secondary activity in Connecticut and Arizona. Representative recent procurements include the City of Austin (IFB 2200 BYS1051 REBID, posted May 11, 2026, due June 9, 2026) seeking 38 percent sodium bisulfite solution for wastewater treatment plants on an as-needed basis with local business evaluation discounts up to five percent; the City of Tallahassee (IFB-067-26-CPW, posted May 1, 2026, due June 16, 2026) issuing a five-year magnesium hydroxide slurry contract with local vendor preference available for Leon County area businesses; the City of Temple, Texas (BID 510227, posted May 15, 2026, due June 10, 2026) procuring liquid ammonium sulfate at 875,000 wet pounds annually with five percent local preference pricing for Temple-based vendors; and the City of Griffin, Georgia (ITB #26-008, posted April 29, 2026, due May 28, 2026) soliciting multiple water treatment chemicals on a line-item basis with awards to lowest responsive bidders on individual items. Contracts typically require fixed pricing for the initial contract year, NSF certification, U.S. manufacturing compliance where applicable, and delivery within 48 to 72 hours of order placement during business hours.
