Environmental remediation of persistent organic pollutants, per- and poly-fluoroalkyl substances

   Department of Chemical and Process Engineering

   Friday, July 22, 2022  Funded PhD Project (UK Students Only)

About the Project

PFAS are a group of >4,700 man-made chemicals used across a range of applications such as fire-fighting foams, waterproofing for clothes, and non-stick cookware, among others. The properties of PFASs, due to their high number of fluorine atoms, leads to unique behaviour and stability which were sought after commercial properties. But these properties also mean that PFAS are extremely difficult to remove from the environment using conventional water or soil treatment technologies. PFAS are also bioaccumulative and harmful to human and animal health.

At Surrey, in collaboration with Arcadis, we have developed sonolysis (the use of ultrasonic waves to break down a substance) to treat PFAS. Sonolysis uses sound waves at frequencies generally between 20 kHz to 1 MHz to facilitate cavitation bubbles in water. The bubbles collapse during compression cycles, and significant energy is released in the form of point sources of extreme heat and plasma-like conditions. Sonolysis is one of the most promising technologies to remove PFAS from our environment, however for application to contaminated soils and waters, needs coupling with other technologies. This PhD will aim to adress PFAS treatment challenges in the environment. 

Supervisor: Dr Madeleine Bussemaker
