ZwitterCo, a fouling-resistant membrane technologies provider, has secured US$5.9 million in Series Seed financing to scale its water treatment and advanced separations solutions.

The funding round was led by Mann+Hummel Corporate Ventures in collaboration with R-Cubed Capital Partners, with additional support from Burnt Island Ventures and individual investors.

ZwitterCo, a spin out of Tufts University, has developed a hydrophilic membrane that it says can filter historically un-filterable process water and wastewater that is rich with fats, oils, proteins and other hard-to-remove organic compounds. The US company is targeting applications in bioprocessing, agricultural waste treatment, food and beverage, and other industries where standard membrane solutions foul and quickly degrade in performance.

With the new funding, ZwitterCo will complete final field testing in several key markets and expand commercial production.

“There are clear and urgent challenges in water that ZwitterCo’s solutions can address, including opportunities to expand reuse, solve production bottlenecks, ensure discharge compliance, convert waste streams into valuable products and more,” said Alex Rappaport, CEO of ZwitterCo. “We are humbled that our membranes are providing tangible solutions to these challenges. Our work with Mann+Hummel and our other partners has been critical for scaling quickly and getting our products into these industrial applications.”
