About Spiral Membranes

Nobody knows spiral membranes better than the people who invented the technology

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.
