Membrion, a ceramic desalination membrane innovator, has raised $20 million in Series B1 funding to accelerate commercial-scale deployment of sustainable wastewater treatment technologies. The round was anchored by Pangaea Ventures, PureTerra Ventures, Ecolab Inc., and W. L. Gore & Associates, with participation from The Lewis Family Office and existing investors including Safar Partners, Lam Research, Indico Ventures and Giantleap Capital.
This latest investment brings Membrion’s total funding to $43 million since inception, fuelling rapid growth as the company transforms industrial wastewater into a reusable resource. Its flexible ceramic membrane systems enable the reclamation and reuse of up to 98% of industrial wastewater, helping customers lower water consumption, reduce chemical waste and achieve regulatory compliance.
“I’m thrilled to welcome a group of new investors who share our conviction that water circularity and resource reclamation are essential to building a better world. Their commitment accelerates our momentum as we continue to deploy more full-scale industrial installations that are already saving customers hundreds of thousands of dollars annually,”

Pangaea Ventures Partner Sarah Applebaum said the company has reached an exciting inflection point as demand for resource-efficient technologies grows. “With each deployment, Membrion reduces water consumption, chemical waste and energy use while delivering tangible ROI for their customers,” she said.
Ecolab’s Vice President and General Manager for Sustainable Growth Solutions, Calvin Emanuel, added: “As a global leader in water, we are committed to accelerating a circular approach to industrial water management. We are proud to support Membrion’s innovation and the potential of their ceramic desalination membranes to recover and reuse water, reduce waste and protect vital resources for future generations.”
Existing investor PureTerra Ventures reaffirmed its support, citing Membrion’s growing commercial traction and strong technical progress. W. L. Gore & Associates also joined the round, with Venture Fund Leader Ed Rubin noting that Membrion’s mission aligns closely with Gore’s focus on material science innovation for societal benefit.
Membrion’s solutions are being adopted across multiple industries for their flexibility and ease of integration into existing facilities. Once installed, the systems expand operational capacity, improve process efficiency, and enable water reuse that supports long-term sustainability goals.
