Toray Other Brackish Water Membranes

Toray Other Brackish Water Membranes

Our selection of Toray membranes are designed to filtrate feedwater for the removal of TDS, salt, and other unwanted impurities. The high rejection capabilities of these membranes will ensure the production of clean and pure water with additional polishing before it is saved for distribution to our clients. 

A great degree of Toray's  reputation of a supplier of greatly-designed membrane elements can be attributed to over 3 decades of manufacturing and providing ISO-9001 certified membranes in the United States.

Pure Aqua has over 20 years of experience as a global provider of Brackish Water Membranes from Toray which are designed to deliver high flux and high rejection, ultra low pressure for low salinity applications, and a variety of other utilizations in the water treatment industry. 

Toray reverse osmosis membrane products are functional membrane elements with excellent quality and high performance.

Toray products are high rejection and high flux RO elements that have been meeting the high level requirements of our customers in many applications including:

Ultrapure water production for semiconductor and other industries
Seawater desalination
Wastewater treatment

Toray membrane products are manufactured in three locations allowing for convenient global distribution. Toray’s manufacturing plants in Ehime Japan, TBMC in China, and TMUS in US are all certified for both ISO9001 and ISO14001. Also, TMUS the plant has achieved the National Sanitation Foundation (NSF) certificate for their low-pressure brackish products.

Toray manufactures RO elements using second-generation automated rolling equipment developed by Toray Industries. The automatic winding of spiral wound elements provides a more durable, higher membrane surface area product versus traditional hand rolled elements. The RO elements manufactured are dimensionally compatible with all major membrane manufacturers providing easy upgrade and retrofit opportunities. The high quality (high rejection, high flow characteristics) of Toray's products make them ideally suited for use in applications such as municipal drinking water, seawater desalination and the production of ultra-pure water for the semiconductor and power industries.

Features and Quality of Toray Reverse Osmosis Membrane Elements

  • High rejection and high flux membrane- Both high rejection and high flux membranes are developed with Toray's extensive experience in polymer chemistry.
  • Choice in membrane material- Two types of membrane materials are available: thin film composite (TM and SU series) and cellulose acetate (SC series). Both membrane types are manufactured by Toray for use in a wide range of water treatment applications.
  • Used in many applications- With such a broad range of products such as high salt rejection or ultra-low pressure elements, the optimum element can be selected for any application ranging from ultrapure process water to seawater desalination.
  • Experience- Toray was the first manufacturer of reverse osmosis membrane elements in Japan and has 25 years of experience in the application of numerous processes around the globe.
  • Complete service and support- Toray has established a complete service system to assist customers based on their extensive experience and technical data accumulated through many years and a variety of applications. Should any problem occur, appropriate technical support is readily available worldwide.

Toray's Japanese membrane manufacturing factory has ISO-9001 and ISO 14001 certification from the Japan Quality Assurance Organization. Their U.S. manufacturing facility has received NSF inspection and certification on a number of products manufactured there.
