International brand dossier
DuPont-Filmtec Membranes
DuPont Water Solutions is a global water purification and separation portfolio built around recognized technologies such as FilmTec membranes, AmberLite resins, inge ultrafiltration, and related industrial separation materials.
Its influence comes from breadth: the same corporate water platform is used in drinking water, desalination, industrial reuse, pharmaceutical and food processing, electronics ultrapure water, and selective purification.
DuPont-Filmtec Membranes's position in RO/NF membranes and related equipment is defined by product families such as 8-inch Brackish-Water RO Elements, 8-inch High-Purity-Water RO Elements, 2.5-inch Low-Energy Brackish-Water RO Elements, and 8-inch Low-Energy Brackish-Water RO Elements.The portfolio is best understood inside brackish water, seawater desalination, ultrapure water, process separation, reuse, degassing, and membrane system packaging, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.

How to choose DuPont-Filmtec RO Membranes
This section answers two questions: which main product families DuPont-Filmtec offers, and which parameters to compare before choosing a specific model.
Step 1: Choose a product family by application
The main families shown on this page are 8-inch Brackish-Water RO Elements, 8-inch High-Purity-Water RO Elements, 2.5-inch Low-Energy Brackish-Water RO Elements, and 8-inch Low-Energy Brackish-Water RO Elements. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
Step 2: Confirm the model by key parameters
After choosing a product family, compare feed salinity, target salt rejection, permeate flow, operating pressure, fouling tendency, and element size and connection. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
