DOW FILMTEC Brackish Water Reverse Osmosis (RO) 8" Membrane Elements

Pure Aqua, Inc. builds the complete Brackish Water Reverse Osmosis systems, as well as stock all major components for your maintenance needs. Controls, replacement cartridge filters, high pressure pumps and membrane elements. Reverse Osmosis (RO) technology, also known as hyper filtration, is used in every one of our stock and custom-made reverse osmosis water treatment systems to purify water by removing salts, contaminants and other impurities. Our full line of Brackish Water Reverse Osmosis Systems are available with a wide range of capacities (up to one million gallon per day) and TDS (up to five thousand parts per million total dissolved solids). In this way our systems set the standards in the water treatment industry. Our friendly knowledgeable engineers and staff are always on hand to help and answer any questions or concerns you may have. We design each of our systems to be plug-and play, with all membranes, pumps, controls, manuals, filters, operating, and piping installed and ready to go.

Brackish Water RO units are used all over the world in many regions where clean potable water is scarce. It is ideal for food and beverage industries, potable drinking water, hospitals, agriculture, hotels & resorts, water bottling & ice making, pharmaceuticals and more. No matter your water application needs, Pure Aqua, Inc. can provide industry standard or custom designed brackish water RO machines.

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 wastewaters. 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
