CycloPure, Inc.

CycloPure, Inc. Cyclopure is solving water contamination problems by filtering micropollutants with pioneering adsorption technologies. Dr. Dichtel is the Robert L.

Contamination of water resources by micropollutants is a global health and environmental problem, with greatest risk to infants and unborn children who are most vulnerable to the toxic loads of these chemical compounds. Advanced analytics have shown that trace organic compounds including residuals of pharmaceuticals, pesticides, detergents, and cosmetics, are persistent in water and retain toxic effect at extremely low concentrations. CycloPure was formed to commercialize novel adsorption technologies pioneered in the lab of Will Dichtel at Cornell University. Letsinger Professor of Chemistry
at Northwestern University, and heads the Dichtel Research Group in the University’s Department of Chemistry. Using these technologies, CycloPure is developing a new class of highly adsorbent and sustainable materials for rapid removal of micropollutants from water. The company’s water treatment technology can be incorporated into a variety of filtration products for domestic, industrial, hospital and municipal applications, including purification and conditioning. CycloPure is also developing the technology for use in functionalized fabrics to remove volatile organic compounds (VOCs) and other contaminants from air.

Our Story

We are a material sciences and technology company whose mission is to make drinking water safe for everyone, everywhere. We are commercializing a new class of selective and powerful adsorbents called High-Affinity Cyclodextrin Polymers (HACPs) that are uniquely capable of removing the toxic micropollutants that contaminate much of our drinking water supply and threaten the health of millions every day. These micropollutants include industrial chemicals, pharmaceuticals, and pesticides that, even at trace concentrations (parts per billion), have been linked to multiple cancers, endocrine disorders, thyroid disease, and immunotoxicity.

Because they exist at trace concentrations, micropollutants easily pass through the municipal water treatment plants which supply tap water to over 85% of the U.S. population. Many also pass through Point-of-Use water systems that millions have installed in their homes. It is the reason that some micropollutants, such as carcinogenic per- and polyfluoralkyl compounds, are now found in the blood serum of 97% of Americans.

Our invention of porous High-Affinity Cyclodextrin Polymer (HACP) adsorbents represent a breakthrough solution for the safe, rapid, and cost-effective removal of toxic micropollutants from water. Our patented technology can be easily incorporated into most water treatment applications including municipal drinking water and wastewater treatment systems, industrial water treatment facilities, and in consumer Point-of-Use water purification products.
