Company Profile


Based in Seattle, WA, USA


Technology & equipment suppliers


Membrion, founded in 2016, is a manufacturer of ceramic ion exchange (IX) membranes for use in electrodialysis/electrodialysis reversal treatment processes. These membranes, which contain silica, are more durable than traditional polymeric IX membranes, as their texture limits scaling and they can handle harsh oxidizers, and therefore can be used in industrial wastewater that would traditionally be unsuitable for membrane treatment. Moreover, these CeramIX® membranes facilitate higher water recovery rates and lower electricity costs than polymeric membranes. They also provide brine management solutions, facilitating stream segregation and brine recycling. The company recently completed a pilot using its ceramic IX membranes in cooling water treatment that produced significantly reduced cooling tower blowdown. Membrion announced a $7M Series B funding round in January 2023 led by PureTerra Ventures, with participation from Safar Partners, GiantLeap Capital and Freeflow, and existing investors.

Area of operation

Membrion is headquartered and operates in Seattle, WA, USA.

Projects of interest

A collaboration between Membrion and W L Gore & Associates was announced January 2023 which will develop ultra-thin ceramic membranes for energy-efficient desalination of wastewater streams – pilots for this project are scheduled.
A Strategic partnership was established as of November 2022 with Magna Imperio Systems Corp (MI Systems) to integrate CeramIX with END technology to produce high quality and reliable water treatment with maximum recovery rates and efficiency.
