UNSPSC 40161705: Demister pad

Demister and demister-pad work like mist eliminator. It differs in the kind of filter media used. For demisters, the media is wire mesh; for mist eliminators, it is fiber glass, wool, etc.

UNSPSC 40161705 Demister pad is a Commodity code that state and local water and wastewater treatment agencies are procuring not as standalone equipment but as part of integrated clarifier mechanisms, drive systems, and facility rehabilitation projects. Recent opportunities show water treatment plant operations sourcing clarifier equipment, particle counters, drive mechanisms, and full-system replacements—acquisitions rooted in aging infrastructure replacement and hurricane-driven facility upgrades rather than isolated demister pad components. Issuing bodies are municipal water departments and regional water authorities in Florida, Georgia, North Carolina, and Oregon. The Collier County water softening improvements, Seminole County water reclamation facility Class I reliability enhancements following hurricanes Milton and Helene, and Gwinnett County particle counter replacements at filter plants represent the typical issuing pattern: direct-service municipal utilities and county water resource departments managing treatment plant capital projects. A secondary pattern involves sole-source equipment and parts procurement—Holly Hill, Florida's replacement drive shaft for softener #2 and Hillsborough County's five-year integrated equipment and parts contract with DXP Enterprises demonstrate how demister pads and related internals flow through proprietary OEM reseller relationships rather than open competitive procurement.

Geographic concentration is strongest in Florida and Georgia. Recent opportunities cluster in Collier County and Seminole County, Florida (June–July 2026); Gwinnett County, Georgia (March–May 2026); Douglas, Georgia (February–March 2026); and Holly Hill, Florida (sole source, dated April 2026). Charlotte, North Carolina (primary clarifier mechanism, March–April 2026) and Pendleton, Oregon (secondary clarifier rehabilitation, May–June 2026) represent secondary markets. Collier County's sealed-bid IFB for the South County Regional Water Treatment Plant Lime Softening Improvements—Blend Tank (due July 15, 2026, anticipated project budget $3.29 million) emphasizes concrete structures, chemical injection systems, and instrumentation integration rather than demister pads as line items. The City of Charlotte's ITB FY26-ITB-08 for McDowell Creek Water Resource Recovery Facility Primary Clarifier No. 4 Equipment (due April 8, 2026, delivery within forty weeks) specifies 70-foot circular clarifier mechanisms from approved manufacturers (Envirodyne, WesTech, Ovivo/Eimco, Evoqua) with 316L stainless steel construction. Demister pads do not appear as named commodities in these recent solicitations; the code shows limited discrete activity aligned to the code's nominal definition.
