Spiral Membranes OVERVIEW  

The FLUID SYSTEMS® Division of Koch Membrane Systems is where modern
reverse osmosis RO membrane technology for desalination and water
purification got its start.

Take advantage of the KMS proven track record
For more than thirty years, the highly innovative FLUID SYSTEMS® brand of Koch Membrane Systems has been serving the residential and commercial water filtration and purification markets with state-of-the-art membrane elements.

Benefit from our broad experience in your market
Today, our technology is built into a vast array of membranes that go into a wide variety of systems in applications such as:
• Commercial car wash and laundry applications
• Drinking water vending machines
• Bottling plants
• Landscaping and irrigation systems
• Specialized laboratory and industrial applications
• Boiler feedwater makeup units
• Food processing plants
• High purity rinse applications
• Wastewater recovery systems and more

KMS knows your business and supports your needs
Although we also serve giant industrial and municipal customers globally, our business has always focused seriously on local small- to medium- size business requiring clean water on demand.

When it’s a question of membranes, KMS has the answer
With more than fifty different types of TFC® (Thin Film Composite) membranes in our product catalogue, there is sure to be one that incorporates the right size, the performance standards, and price range to fit your individual needs.

                THEN  
ROGA® Module 1, circa 1964


                 NOW
The world's first 18" diameter spiral RO Element. Years ahead in proven performance with impressive cost savings.

Accommodating a full range of ratings, sizes and pressures, KMS spiral wound elements give you the broadest choice possible:
Element capacities range from 750 gallons to over 70,000 gallons per day, with salt rejection ratings over 99.7%. Sizes range from 2.5” to 18” in diameter. Because they are made to industry standard dimensions, KMS elements can replace all popular models on the market today, without the need for special adapters.

To save energy, these elements can operate at pressures as low as 55 psi for low TDS applications all the way up to 1200 psi for seawater desalination. Many sizes are available in either a tape wrap or FRP wrap for extra strength and durability.

KMS membranes are backed by KMS service and maintenance
Our KOCHTREAT® and KOCHKLEEN® products along with our KMS ASSIST® programs will help improve the longevity of your membranes regardless of membrane type.

When you are working with Koch Membrane Systems, you are working with the leaders in Membrane Technology for Water Applications of any size and purpose
Fluid Systems Inc. is where modern reverse osmosis RO membrane technology for desalination and water purification got its start.

Truly, a pioneering powerhouse in membranes, Fluid Systems developed:
• The first patented spiral wound element (1967)
• The first large-scale RO system (1970)
• The first large-scale RO planate treating (1974)
• The first commercial 8-inch diameter spiral wound element (1976)
• The first commercial thin-film polyamide composite membrane TFC (1977)
• The first large-scale sea water desalination system (1977)
• The first commercial 12.75-inch diameter 60-inch long Magnum elements for the largest
  brackish desalting plant in the world, Yuma.AZ (1982)
• TFC® S “softening” membrane elements (1991)
• ULP ultra low pressure brackish water membrane elements (1995)
• The first (and world’s only) commercial Thin-Film Composite 60-inch long spiral-wound
  element, TFC® Magnum®  (1995)
• TFC® Magnum®  high-area elements (1966)
• TFC® XR™ “Xtreme Rejection” brackish water membranes elements for maximum silica
  and TOC rejection (1997)
• TFC® SR® 2 “Selective Rejection” membranes for highly efficient removal of naturally
   occurring organic material and divalent ions at very low operating pressures (1999)
• TFC® MegaMagnum®  the world’s largest spiral-wound element, 18-inch diameter,
  60-inches long, (2002)

Imagine what FLUID SYSTEMS® membranes can do for you and your business!

After Fluid Systems, Inc. was acquired by KMS, the pioneering spirit of Fluid Systems was carried on in the FLUID SYSTEMS®  line of membrane elements. These include:
