Technology Profile
SRP-funded small business CycloPure, Inc. , has developed a new product, DEXSORB+, which works to rapidly remove per- and polyfluoroalkyl substances (PFAS) from contaminated water supplies. CycloPure recently announced that in addition to SRP funding, they have raised an additional $3.5 million to accelerate the commercialization of their DEXSORB products. This will help them to make the technology available to consumers and municipal drinking water plants impacted by PFAS and other contaminants.
| Technology | The company's line of DEXSORB adsorbents are based on innovative technology that converts renewable cyclodextrins, derived from corn starch, into highly-adsorbent materials capable of eliminating a variety of pollutants from drinking water. |
|---|---|
| Innovation | In their new DEXSORB+ product, they created a process that enhances the binding ability and found that it resulted in a seven-fold improvement in the removal of 20 short and long chain PFAS. For example, according to the company, DEXORB+ can remove more than 95 percent of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) even at low concentrations in only 30 minutes. |
