Description

As the agency reported it.

Polyfluoroalkyl substances removal during coagulation flocculation process can be improved by increasing the hydrophobic interactions of polyfluoroalkyl substances molecules with the flocs. This project proposes to utilize hydrophobic ionpairing HIP as a pretreatment to enhance the removal of both shortchain and longchain polyfluoroalkyl substances during coagulation flocculation process. Hydrophobic ionpairing is a concept by which an ION pair complex is made through the interaction of a hydrophilic ION of interest with a hydrophobic counterion making the overall molecule hydrophobic. In the case of polyfluoroalkyl substances the project proposes to add a cationic hydrophobic ionpairing additive to the contaminated source water to enhance the hydrophobic interaction of polyfluoroalkyl substances with flocs and entrapment of hemimicelles micelles of polyfluoroalkyl substances complex within the flocs. The overall goal of this proposed project is to optimize the type dosage and operating conditions of the enhanced coagulation flocculation system for the removal of polyfluoroalkyl substances mixtures.
