DOW FILMTEC Brackish Water Reverse Osmosis (RO) 4" 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 technology, also known as water 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 reverse osmosis 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 reverse osmosis machines.

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 reverse osmosis membrane for water purification systems. To date, more than 1,000,000 FilmTec membranes have been installed in water treatment systems worldwide.

Benefits of DOW FILMTEC Tap and Brackish Water Commercial Elements

Reverse osmosis has become the preferred choice for water purification system needs in lieu of conventional demineralization. Reverse osmosis membranes, such as Dow Flmtec membranes, have also been adopted as pre-treatment tools for water deionizers systems. Here are some of the benefits that Dow Filmtec provides to those in need of reverse osmosis applications:

  • 99% of total dissolved solids are removed by reverse osmosis systems

  • Reverse osmosis membranes eradicate unwanted impurities such as bacteria, viruses, chloride, fluoride, and etc.

  • LP & XLE features decrease operating costs because of less energy needs

  • TW30 features create greater value of life because of a lower proneness to fouling

Applications for DOW FILMTEC Membrane Installation

When & How to Change Dow Filmtec?
DOW Filmtec membranes are considerably durable and robust layers that do not require replacement for up to 5 years. Despite this, there are certain conditions which will negatively impact the life of the membranes, and will require an immediate change of your membranes for continued usage. Such condition can occur when your membrane builds up an unrecoverable amount of fouling. Membrane fouling, if treated in a timely manner, is a common occurrence and can be easily remedied. However if you have already cleaned your membrane and still notice under performance then it is clear that the membrane has reached an irreparable point. Switching your membranes is a simple process which can be done by meticulously following guidelines.
