The Early Years
Koch Membrane Systems, Inc. was established in 1963 as a privately held company known as Abcor, Inc. Its charter was to develop and commercialize processes and equipment based on separation and purification technologies, which originated with scientists from the Massachusetts Institute of Technology.
The Shift In Focus
In 1970, the company added ultrafiltration membranes and systems to its portfolio of separation technologies, which proved to be so successful that all other separation technologies were abandoned. Since then, the company has concentrated entirely on membrane separation and has become a world leader in this field.
The growth of our original company was gradual but well focused. Koch Engineering Company, recognizing the commercial potential of these technologies at the outset, not only provided the seed capital to establish Abcor, but obtained minority ownership position. In 1977, Koch Engineering Company bought out the remaining shares, with Abcor becoming a wholly owned subsidiary. In 1981, the company became Koch Membrane Systems, Inc.
A Global Community
KMS is headquartered in Wilmington, Massachusetts, with offices throughout the world. With manufacturing plants in Wilmington and Aachen, Germany, KMS has flourished thanks to our ongoing development of superior filtration products, as well as through acquisitions of leading companies in the field. Among the acquisitions were Romicon, Inc. (1991), Fluid Systems Corporation (1998), and Puron AG (2004).
What people say
We solve the world’s most critical water treatment challenges. Pure and simple.
Water & Wastewater Solutions
Listening to customers has helped us develop the world’s most comprehensive and innovative family of membranes.
Concentrating, clarifying, and purifying process streams to increase yield and reduce cost.
Industrial & Life Sciences Solutions
KMS produced the industry’s first spiral wound RO element. Robust, energy efficient, and economical, it is made from layers of flat-sheet membranes and feed separators wrapped around a hollow core. Feed solutions enter one end of the element, flowing under pressure through the membrane into permeate channels, spiral to the central core, and exit as permeate. This configuration offers the highest membrane-packing area with the smallest footprint.
Offered in a variety of materials, diameters, and lengths, spiral membranes have become the most prevalent of membrane configurations and are frequently used in seawater desalination, brackish water treatment, water softening and organics removal, and water reclamation and reuse. We also offer sanitary spirals for dairy and industrial biotechnology uses.
Thanks to the rugged construction of KMS tubular membranes, they can easily process high suspended solids, and concentrate product proficiently and repeatedly to high end-point concentration levels without plugging, making them ideal for recovering wastewaters, and clarifying juices.
Available in microfiltration and ultrafiltration, our tubular membranes operate in tangential, or cross-flow, design where process fluid is pumped along the membrane surface in a sweeping action. We offer a wide selection of durable options that are easy to operate and clean, serving a variety of industrial and municipal applications.
XXI century: From wastewater to Resource Source
Towards a new paradigm based on sustainability, where wastewater now turns into a source of energy, nutrients and simultaneously, a water resource suitable for reuse.
In this context, LIFE MEMORY project targets for the sustainable production of reusable water demonstrating the feasibility of an innovative technology: the Submerged Anaerobic Membrane Bioreactor (SAnMBR).
