How it works
Spiral-wound thin-film composite elements. Feed water flows along the membrane surface under pressure; purified permeate passes through and spirals to the central collection tube, while the rejected salts leave as concentrate. Performance is quoted at a defined test condition - change the feed salinity, pressure, temperature or recovery and the delivered flow and rejection change with it.
Technical notes
Permeate flow and rejection are test-condition figures
DuPont measures every element on a standard solution stated on its data sheet. Two elements are only comparable at the same conditions. System design should use projection software with your actual analysis, not the headline number.
Stabilized vs minimum rejection
The stabilized value is the expected performance once the element has lined out; the minimum is the guaranteed floor for an individual element. Individual permeate flow rates may vary from nominal - DuPont states the tolerance on the sheet.
Free chlorine
Polyamide composite membranes are oxidised by free chlorine. DuPont's sheets state the tolerance in ppm; dechlorinate ahead of the membrane and control it continuously.
Common questions
How do I get a price?
This item is quoted rather than listed. Send us the model, the pack size and the quantity and we
will come back with price, lead time and freight.

408-969-2688.
Is the data on this page the manufacturer's own?
The description and attributes come from the manufacturer's published catalogue data. Where
DuPont does not publish a figure we leave it out rather than estimate it.
What warranty applies?
DuPont's Product Data Sheets state: "NO WARRANTIES ARE GIVEN; ALL IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE ARE EXPRESSLY EXCLUDED." Performance
depends on feed water and operating conditions that the manufacturer does not control, so no
performance warranty is offered by them or by us. Confirm suitability for your duty before ordering.
Will this element fit my vessel?
These are industry-standard spiral-wound elements. Check the diameter and length in the table
against your pressure vessel, and confirm the endcap or interconnector arrangement - some models
use interlocking endcaps that are not interchangeable with a standard adapter.
