A process for treating water contaminated with refractory organic matter, such as per- and polyfluoroalkyl substances (PFASs), comprising the following steps: (a) lowering the pH of the water for hydrolysis of organic matter; (b) subjecting the water with lowered pH to catalytic reduction by zero valent iron for organic matter degradation; (c) optionally aerating the water to oxidise the iron to ferric hydroxide; (d) optionally clarifying the water; and (e) optionally a catalytic advanced oxidation step. A system for conducting the process is also disclosed. |
