About Aclarity

Aclarity, Inc. operates at the forefront of environmental technology, specifically targeting the destruction of per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals." Founded in 2017 by Julie Bliss Mullen, the company emerged from her Ph.D. research at the University of Massachusetts, Amherst. Mullen's background in environmental engineering, including work with the EPA and Engineers Without Borders, directly informed the company's mission to solve critical water contamination issues.

Read full description

The core of Aclarity's business is its proprietary electrochemical oxidation technology, embodied in the Octa™ system. This system passes contaminated water through a reactor where an electric current generates strong oxidants that break the resilient chemical bonds of PFAS, destroying the compounds and leaving behind harmless byproducts. Aclarity's process is designed to be a definitive solution, unlike traditional methods that merely separate and relocate the hazardous materials. The technology has demonstrated its effectiveness by destroying PFAS compounds by up to 99% in field applications.

Aclarity's business model involves providing these water treatment systems and hardware to a diverse client base that includes landfills, centralized waste treatment facilities, and various industrial sectors such as pulp and paper, textiles, and food and beverage manufacturing. The company targets customers with highly concentrated PFAS streams, like landfill leachate, where its technology offers a significant cost advantage over traditional disposal methods. By providing on-site destruction, Aclarity helps clients mitigate regulatory risks, eliminate transportation costs for hazardous waste, and reduce maintenance expenses. Having raised a total of $20.2 million over several funding rounds, including a significant $15.9 million Series A in late 2023, the company is scaling its manufacturing and commercial deployment efforts.
