Our Vision

Our vision is to be recognized as the leading specialty membrane supplier.

TriSep has a deep pool of engineering expertise along with the capability to quickly make customized products. This combination of talent and manufacturing ability allows us to produce membranes uniquely suited to our customers' needs.

Whether our customers need replacements for other manufacturers discontinued products, specialty element construction for challenging process environments, or a partner for new product development, TriSep offers solutions that a standard membrane supplier cannot provide. 

Our History

TriSep Corporation has been involved in the development and manufacturing of spiral wound membranes for over 25 years. When Peter Knappe and James Bartlett started the company in 1989, it solely produced cellulose acetate membranes.

TriSep has grown from its humble beginnings to become a global supplier of membrane products. We currently produce a wide variety of membranes from reverse osmosis, nanofiltration, ultrafiltration, to microfiltration as well as membrane cleaners and scale inhibitors.  

Some of our signature developments include the the X-20™ low fouling membrane, our TriPol™ and TriClean™ line of scale inhibitors and membrane cleaners, the TurboClean® line of sanitary elements, as well as the backwashable SpiraSep™ and iSep™ elements.
