§ Private Profile · Woburn, MA, USA
ZwitterCo is a technology company.
ZwitterCo develops advanced membrane filtration systems utilizing proprietary zwitterionic polymers. These specialized membranes are engineered to repel fats, oils, and greases, enabling stable and efficient treatment of highly impaired industrial and agricultural wastewater. The technology offers a robust solution for challenging separations, maintaining performance in environments where conventional membranes rapidly foul and degrade.
The company was co-founded in 2018 by Alex Rappaport, who serves as CEO, and Dr. Ayse Asatekin, a chemical and biological engineering professor at Tufts University. The core insight originated from Dr. Asatekin's academic research into zwitterionic polymer technology. Rappaport, a Tufts alumnus, identified the potential of this scientific breakthrough to address pressing global water scarcity issues, leading to the commercialization of the technology for enhanced water treatment and reuse.
ZwitterCo’s products are adopted by industries grappling with complex wastewater streams, including pharmaceutical, food processing, and various manufacturing sectors. The company’s mission centers on transforming the economics and practicality of water reuse. By providing durable and high-performing filtration, ZwitterCo envisions a future where industrial and agricultural operations can sustainably manage and reclaim water, contributing to global water security.
