Sepro Membranes, Inc.

Sepro is a manufacturer of sheet membranes, spiral-wound membrane elements, and associated equipment. We are an experienced team of professional engineers and scientists whose average involvement in the membrane industry exceeds 20 years.
We offer thirty-seven proprietary membranes with a choice of backing materials to suit both mainstream and niche separation applications. We pride ourselves in providing quick response, short delivery times, and the flexibility to manufacture custom products.

As the functional component of any membrane separation is the membrane itself, Sepro is able to focus on the best membrane solution for an application by offering customers a total of thirty-seven different types of membranes. These include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis sheet membranes. Most membranes are available for purchase in the form of rolls of membrane or as spiral-wound elements, all packaged and shipped dry without the need for liquid preservatives. Elements are available in “standard” sizes or as custom elements tailored to specific customer needs in terms of dimensions and materials of construction. Sepro also provides to customers complete membrane systems, system components, and equipment for manufacturing membrane products.
