DOW FILMTEC™ Reverse Osmosis Membranes - Pure Aqua, Inc.

DUPONT Filmtec Membranes

DUPONT FILMTEC™ Membranes

Filmtec membrane elements provide unmatched quality in separating the contaminants from concentrated water ending with purified clean water. These membrane filtration products are exceptionally efficient in water treatment applications that include industrial, commercial, municipal, and consumer-related concerns.

Some of the most substantial and beneficial technologies such as reverse osmosis (RO) and nanofiltration (NF) have been put to use by FilmTec™ which not only have extremely high rejection capabilities, but utilize less energy to produce purified water than conventional elements

Dupont's FilmTec membranes highlight a spiral wound design and are centered on the polyamide membrane of the thin film composite FT30 that has already become the accepted standard for reverse osmosis performance. The standard Filmtec membrane is composed of 3 layers: an ultra-thin polyamide barrier sheet, an interlayer of microporous polysulfone, and an extra-strong polyester support web. These RO membranes have been modified and optimized regularly to deliver higher rejection, increased membrane flux, and minimal fouling efficiency. The Filmtec membanes of now are exceptional in efficiency and durability, without the wrapped or attached deficiencies that may lead to other membranes to fail. Satisfactory comprehension and implementation of the fundamentals of reverse osmosis will mitigate problematic and expensive potential pitfalls.

Users can find our industrial/commercial Filmtec membrane element when there is a demand for the highest quality water or the most minimal cost of water production.

Our line of Dupont Filmtec membranes provide water treatment operators with the latest and cutting-edge performance, including an innovating approach for maximum efficiency, consistency, dependability, and cost-management. A Filmtec membrane is designed to significantly increase system output, enhance quality of the water and prolong productive element lifespan in your reverse osmosis system. Additionally, our dupont membrane is more robust and works more efficiently than most other (RO) elements over the broadest pH range (1-13).

High Rejection:

Dupont Filmtec membranes deliver the highest rejection of total dissolved solids that are vital to the efficient functioning of any water treatment system. Membrane technology polyamide chemistry, allows for excellent resistance to organic and biological contamination and is associated via an engineered 34 mil feed spacer design that prevents degradation and decreases drop in pressure across the item.

Low Energy:

A Low energy Filmtec membrane is designed to save energy and costs while maximizing system output with unmatched efficiency. Unlike other competing membrane elements, these ro membranes ensure users to perform well over the operating lifetime. For this reason, Dupont membrane elements are much more stable and operate more efficiently than other reverse osmosis membranes. Such modern designs benefit from lower installed unit costs by reducing component count and installation costs.

Fouling Resistant:

Filmtec membranes are fouling-resistant and feature patented FR membrane technology that provides unparalleled fouling resistance and cleanliness in both drinking and non-potable purposes. A Dupont membrane filter delivers better performance over the functional life of the material, without the need for oxidative post-treatments.

Thin-Film Composite (TFC Membrane) design

The TFC membrane consists of three layers: a polyester support web, a microporous polysulfone interlayer, and an ultrathin barrier coating on the top surface.

FilmTec thin-film composite membranes (TFC membranes) are the world’s leading RO membrane for water purification systems. To date, more than 1,000,000 FilmTec membranes have been installed in water treatment systems worldwide.
