Electrocatalytic Oxidation: The Science Behind Elcat

Electrocatalytic oxidation (Elcat) is a process that utilizes electrochemistry to degrade pollutants in wastewater. The core principle lies in the application of an electric current to a wastewater stream passing through an electrode system. This current triggers a chemical reaction, oxidizing pollutants and breaking them down into less harmful compounds or even harmless byproducts.
