About Membrion

Membrion is a Seattle-based startup that is working to increase the effectiveness and efficiency of wastewater treatment by developing ceramic membranes that can filter out impurities and contaminants from wastewater, allowing it to be reused for various purposes, including irrigation, industrial processes, and even drinking water.

  • The longevity and endurance of Membrion's ceramic membranes as compared to more conventional polymer-based membranes is one of their main benefits. There is less of a need for regular replacements because they can survive harsh chemical and heat environments and do not degrade over time.


  • Research from the University of Washington served as the foundation for Membrion's technology, and the firm has received support from a number of organizations, including the National Science Foundation and the Bill & Melinda Gates Foundation.

  • Membrion's ceramic membranes have potential uses beyond wastewater treatment in fields like biology and pharmaceuticals where high-purity separations are required.

  • Membrion, which was founded in 2016 and emerged from the University of Washington, intends to solve a problem in wastewater treatment where current options force businesses to truck water away rather than treat it there and then.

  • It sells ceramic desalinization membranes that can be used to treat toxic runoff from industrial operations, eliminating salt and heavy metals like lead, mercury, arsenic, and copper.

  • The more sustainable solution, on-site water treatment, is becoming a financially viable reality as pilot programmes expand into full commercial installations.

  • A ceramic desalination membranes allows for the recovery of up to 98% of water in challenging conditions,

Membrion's Founder

Greg Newbloom is the co-founder and CEO of Membrion. By using ceramic, Greg and his talented team have given the conventional EDR build a twist, broadening its scope of use. They are eager to assist this special technology in realising its potential.

  • Greg is a fantastic leader. After years of research into filtering technologies for use in fuel cells and water desalination systems, Newbloom formed the business. COO Philip Pickett, a seasoned executive with venture-backed power infrastructure and renewable energy businesses, joins him.

  • With training in materials science and engineering, Newbloom previously held a research position at the University of Washington, where he contributed to the creation of the technology that would later serve as the foundation for Membrion's ceramic membranes.
