Water purification and separation technologies provider DuPont is launching 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.

UF membranes are commonly used in the dairy industry to concentrate milk proteins, recover whey proteins and produce milk powders. Integrated pre-filters target particulate fouling and membrane lifespan. Additionally, dairy plants require high-purity water for cleaning, sanitation and processing.

“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,” says Dorie Yontz, global marketing leader, Drinking Water and 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.
