Koch / Fluid Systems Membranes
For over 30 years, Koch Membrane Systems (KMS) has been developing and manufacturing state-of-the-art
membranes for food, dairy, juice, vinegar, beverage, industrial water, municipal water, ultrapure/high purity
water, automotive, pharmaceutical, petrochemical, textile, desalination, and scores of other applications
worldwide. KMS provides tubular, spiral, and hollow fiber membranes for microfiltration (MF), ultrafiltration
(UF), nanofiltration (NF), and reverse osmosis (RO). Thanks to a recent acquisition, KMS is now a provider
of submerged membranes for membrane bioreactors used in industrial and municipal wastewater treatment.
More than 15,000 installations use KMS membranes and are operating and performing successfully around
the world.
