HiOx: The Future of Water Treatment
Chapter 1: Techniques
Advanced Oxidation Processes (AOPs)
HiOx technology falls under the umbrella of Advanced Oxidation Processes (AOPs). AOPs utilize highly reactive species, primarily hydroxyl radicals (•OH), to degrade pollutants in water. The fundamental principle of AOPs involves generating •OH radicals which then react with contaminants, breaking them down into less harmful or non-toxic byproducts.
Methods of HiOx Generation
HiOx systems employ various methods to generate •OH radicals, each offering unique advantages and limitations:
1. Ultraviolet (UV) Oxidation:
