UNSPSC 47101549: Gravity filter

A type of equipment that is designed for fast filtering of the discharged water by the gravity not filtered on the filter paper opened.

UNSPSC 47101549 Gravity filter is a Commodity code that encompasses replacement parts, maintenance services, and specialized components for water treatment filtration systems operated by state and local water utilities, counties, municipalities, and special districts. State and local governments procure under this code primarily through RFPs and RFQs for replacement filter media, filter housings, filter cartridges, diffuser assemblies, and supporting equipment for municipal water treatment plants, wastewater reclamation facilities, and industrial water systems. Recent solicitations show activity across water conditioning systems, membrane diffusers, dewatering polymers, grit removal equipment, and related treatment plant components, though the code's nominal scope (gravity filtration) does not align uniformly with all tagged opportunities—many recent postings reflect broader water treatment procurement unrelated to gravity-specific filtration mechanisms.

Recent activity under this code spans Texas, Florida, Georgia, California, and Arizona. Texas State University (July 2026) solicited RFP proposals for reverse osmosis and deionized water systems maintenance and services due August 10, 2026. The City of Phoenix (June 2026) issued IFB-26-0382 for Sanitaire membrane diffuser components serving wastewater treatment plants, with offers due July 2, 2026 and a five-year contract term beginning September 23, 2026. Gwinnett County, Georgia (July 2026) solicited competitive sealed bids for solids dewatering and thickening polymer on an annual contract due July 30, 2026, with a four-year initial term and four optional one-year renewals. The City of Tampa (June 2026) issued RFQ 26P00394 for replacement parts for a Sweco Vibro-Energy Separator grit remover due June 19, 2026. Collin College (July 2026) requested proposals for chilled and heating water loop extension under a Competitive Sealed Proposal process, with proposals due July 28, 2026. Activity reflects issuing bodies ranging from state universities and municipal water departments to county water utilities and regional authorities, with procurement driven by equipment maintenance, system upgrades, and compliance with water quality standards.
