This thesis will explore various technological approaches to wastewater treatment, drawing from available literature, with a particular focus on their effectiveness in removing poly- and perfluoroalkyl substances (PFAS). PFAS are a group of synthetic chemicals commonly found in numerous industrial and consumer products. We will examine the materials, techniques, and chemicals utilized in these treatment processes, as well as the properties of PFAS, their persistence, and their potential environmental and health impacts. The thesis will highlight the challenges of managing PFAS contamination and explore sustainable and innovative solutions for their removal. Key methods such as adsorption, ion exchange, and phytoremediation will be studied, with particular attention given to the regeneration of used materials, as this plays a crucial role in the cost-effectiveness and environmental footprint of these technologies. Through this work, we aim to contribute to a deeper understanding and broader adoption of effective technological solutions for managing PFAS contamination in water sources.
