DOW FILMTEC Nanofiltration 4" Membrane Elements

Dow FilmTec membrane elements deliver a spiral wound design that is based on the FT30 thin-film composite polyamide membrane, which has remained as the industry standard for reverse osmosis performance. The FilmTec Nanofiltration membrane possesses three layers: an ultra-thin polyamide barrier layer, a microporous polysulfone interlayer, and a high-strength polyester support web. The nanofiltration membrane has been steadily refined to produce higher rejection, greater membrane flux, and low fouling attainment. The current stock of Filmtec nanofiltration membranes are purely constant in condition and performance, without the taped or glued defects that can bring about membrane failure. Sufficient understanding and implementation of the functions of reverse osmosis can reduce troublesome and costly issues in the future.

Thin-Film Composite (TFC Membrane) design

The Filmtec nanofiltration membranes are designed for eliminating high percentages of TOC and THM precursors with medium to high salt passage and medium hardness passage. The Filmtec nanofiltration membrane is an appropriate option for surface water and groundwater where efficient organic elimination is needed with partial softening.

Accurate implementation of reverse osmosis water purification systems is crucial to assemble the membranes for operational performance and to avert membrane failure due to overfeeding or hydraulic shock. Following the accurate implementation sequence also increases the likelihood of system operating parameters conforming to design specifications so that the quality of water and productivity objectives can be met.

Filmtec nanofiltration membranes are designed to completely eradicate sulfate from saltwater for the purposes of efficient oil production, and other applications. This nanofiltration membrane remains at a high performance during operation at low pressures, and sufficiently eradicates substances greater than .001 microns. The end result is highly clean water that is free of all silica, bacteria, and other microorganisms.

Filmtec nanofiltration membranes are designed to allow for easy separation of organics and saline for wide-reaching industrial and municipal water purification systems that turn out greater than 12 gallons per minute of permeate. These elements are perfect for water treatment operations that require ultrapure permeate water that is free of certain contaminants such as iron, nitrates, salts, and organic substances.
