See what half a century of innovation looks like.

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 Evolution
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, 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).

Romicon's outstanding reputation was based on hollow fiber UF membranes and systems. Fluid Systems Corporation, now fully integrated into KMS, was one of the pioneers of commercial reverse osmosis and nanofiltration membrane products, which lead the industry for desalting brackish water and seawater for drinking purposes. This advanced desalination technology is also used for many industrial applications. Puron developed a submerged membrane bioreactor technology that shows great promise for both industrial and municipal wastewater treatment.

Leading Through Innovation
We manufacture UF, MF, RO, and NF membranes and systems in a variety of configurations including hollow fiber, spiral, and tubular shapes. We also sell equipment in a wide variety of global markets that include municipal drinking water, industrial wastewater, juice, dairy, wine, pulp and paper, automotive, pharmaceutical and biotech, sweeteners, and many, many more.
