Koch – Fluid Systems Membranes

Koch membranes, manufactured by Koch Membrane Systems, include ultrafiltration, reverse osmosis and MBR membrane components and systems used in water treatment. Koch Membrane Systems has been manufacturing membranes for more than 40 years. During that time, through invention, discovery and acquisition, they have expanded their line of products to address most, if not the entire filtration spectrum.

Membrane configurations include tubular, spiral wound and hollow fiber. In addition to mainstream treatment applications, the Koch products address many specialty applications including dairy, wine and juice and paint recovery. Of the major membrane manufacturers, they likely have the widest line of products including complete systems for some applications. In the area of reverse osmosis, they have led in the manufacture of 18″ diameter spiral wound membrane elements, including the development of handling and loading equipment.

After years of operating manufacturing facilities on the east and west coasts of the United States, they have recently consolidated those operations at their longtime location near Boston, MA. Major product brands manufactured by Koch Membrane Systems include Romicon, Fluid systems and Puron.
