Inge™ ultrafiltration modules with integrated pre-filter help save space and capital costs in drinking water and seawater applications

WILMINGTON, Del., April 7, 2026 /PRNewswire/ -- DuPont (NYSE: DD) today announced the launch of Inge™ ultrafiltration modules with integrated pre-filter (iP-F). Where conventional ultrafiltration plant processes require a separate pre-filtration manifold to remove debris and particulates, the integrated pre-filter offering combines pre-filtration and ultrafiltration into a single module housing—which can help reduce plant footprint and the associated capital and operational costs of standalone pre-filtration units.

The new product line maintains the same membrane materials, dimensions, and drinking water certifications as existing Inge™ UF modules, while combining two filtration steps into one. Inge™ UF modules with iP-F are well suited for new installations, plant expansions, and containerized systems where space efficiency and streamlined operations are critical.

"By combining pre-filtration and ultrafiltration into a single unit operation, Inge™ ultrafiltration modules with integrated pre-filter will help customers simplify plant design while protecting their UF membrane investment," said Dorie Yontz, Global Marketing Leader, Drinking Water & Desalination at DuPont Water Solutions. "The result is a more compact, efficient solution that supports reliable performance across a range of water qualities."

Inge™ UF modules with iP‑F can provide consistent permeate quality, pathogen removal, and tolerance to feedwater quality swings—all in a smaller footprint than conventional media filters and traditional UF plant designs with upstream prefilters. System performance and design scenarios can be evaluated using DuPont's WAVE PRO modeling software, helping customers assess treatment configurations as part of the overall process design.

DuPont Water Solutions technologies are helping to purify more than 50 million gallons of water every minute in 112 countries across the world. DuPont offers market-leading technologies to address a variety of challenges faced by water treatment municipalities, seawater desalination plants, and industrial water users, including the microelectronics industry, through a broad portfolio of membranes, resins and complete systems. The team is also innovating solutions that can help balance the world's growing water and energy demands, with products that support the production of electricity, lithium and green hydrogen.

FAQ

What did DuPont (DD) announce on April 7, 2026 about Inge ultrafiltration modules?

DuPont announced Inge ultrafiltration modules with an integrated pre-filter to combine two filtration steps into one module housing. According to the company, the design keeps the same membrane materials, dimensions, and drinking water certifications as existing Inge UF modules.

How do Inge UF modules with iP-F reduce costs for drinking water and seawater plants?

The integrated pre-filter reduces the need for separate pre-filtration manifolds, which can shrink plant footprint and lower capital and operational costs. According to the company, combining steps simplifies plant design and can reduce costs tied to standalone pre-filtration units.

Are Inge UF modules with integrated pre-filter suitable for containerized desalination systems (DD)?

Yes. The modules are designed for containerized systems where space efficiency and streamlined operations are critical. According to the company, Inge iP-F suits new installations, plant expansions, and containerized applications requiring compact, reliable filtration.

Will Inge iP-F change permeate quality or pathogen removal compared with existing Inge UF modules?

The company says Inge iP-F can provide consistent permeate quality and pathogen removal while tolerating feedwater quality swings. According to the company, the integrated design maintains membrane performance and drinking water certifications of current Inge UF modules.

How can engineers evaluate system performance for DuPont Inge iP-F modules before installation?

Engineers can model system performance and design scenarios using DuPont's WAVE PRO software to assess treatment configurations. According to the company, WAVE PRO helps customers evaluate integration of the iP-F modules into overall process designs.
