Our History

When Peter Knappe and James Bartlett started TriSep Corporation in 1989, it solely produced cellulose acetate membranes.  Over the next 27 years, TriSep Corporation grew from humble beginnings to become a global supplier of membrane products. Production began of a wide variety of membranes including reverse osmosis, nanofiltration, ultrafiltration, and microfiltration as well as membrane cleaners and scale inhibitors. 

In 2016, TriSep Corporation was officially acquired by MICRODYN-NADIR, and became MICRODYN-NADIR US, Inc. MICRODYN-NADIR has been applying its products in various industrial and municipal applications for 50 years.  They produce industry-leading microfiltration and ultrafiltration membranes and modules, such as the MICRODYN BIO-CEL® MBR module.  Combined with TriSep's reverse osmosis and nanofiltration membranes, plus specialty products such as TurboClean® sanitary spiral elements, MICRODYN-NADIR has become a one-stop shop with the widest range of membrane filtration products.
