Pure Aqua has over 20 years of experience as a global provider of membrane elements that are designed to be resistant towards fouling, which improves their performance in water treatment operations in adverse conditions. These membranes are manufactured by Dupont/Dow Filmtec for consistent performance, increased productivity, and maximum durability.

Pure Aqua, Inc. installs the entire brackish water reverse osmosis system including stocking all critical parts for your maintenance requirements. Controls, cartridge replacement filters, high-pressure pumps, and membrane components. Reverse osmosis (RO) technology, often recognized as hyper filtration, can be utilized to treat water by eliminating salts, pollutants and other contaminants in each of our inventory and tailor-made reverse osmosis water treatment systems. The technologies in this way set the norm in the water treatment industry. Our helpful professional engineers and workers are always on hand to support and resolve any issues or queries you might have had.

Brackish Water RO systems have been used worldwide in many areas where there is lack of safe potable water. Ideal for food and drink manufacturing, drinking water, hospitals, forestry, hotels and resorts, water bottling & ice production, pharmaceuticals and more. Pure Aqua, Inc. will include industry standard or custom-designed brackish water RO machines, including whatever your water application requires.

DOW FILMTEC membrane installations are designed to diminish the effects of fouling, which makes them ideal for reverse osmosis plant managers and operators facing difficult waters or wastewater. These membranes will provide continuous performance, an increase in productivity, and long-term membrane life. 

DOW FILMTEC membrane elements are suitable for reverse osmosis plant operations that deal with pre-treated waters and are in need of high quality water purification. Brackish water reverse osmosis elements to provide ultra pure water at minimal operational costs for industrial and municipal water applications. These elements deliver less energy expenditures and higher productivity (particularly in cold water).

Thin-Film Composite (TFC Membrane) design

The TFC membrane consists of three layers: a polyester support web, a microporous polysulfone interlayer, and an ultra thin 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.

Advantages of Dow Filmtec Membrane Elements

We have partnered with Dow Filmtec to supply the highest performing reverse osmosis membranes on the market. Filmtec membrane elements are constructed to reduce the disastrous effect of fouling, decreasing operational costs, and optimizing membrane efficiency. Furthermore, Filmtec membrane elements do not require the use of oxidative post-treatments as do other membrane products in order to provide maximum performance over their operating lifespan. These membranes also deliver enhanced durability and more optimal cleaning processes over a wider pH range compared to other elements. Such advantages in these membrane elements have only been engineered through the usage of advanced automated manufacturing technology.

Other benefits obtained through Dow Filmtec membrane elements consist of:

  • Dependable and long-lasting seal durability - Less amount of potential leaking due to a single, non-sliding seal. Equally compressed after being installed
  • Solid leak performance -Greatly reduces the probability of o-rings rolling off their grooves or damaged in some way during performance
  • Lubrication unnecessary during operation – Non-use of lubrication for the purposes of preserving the quality of the permeate, will not endanger sealing performance
  • Exceptional compatibility – Dow Filmtec’s next generation elements are fully compatible replacements for existing hardware
