Advanced Oxidation Processes use strong oxidizing agents to reduce pollutants and sanitize water.
As outlined in an industry article, existing methods include injection, catalysis or irradiation, separately or in combination, under mild temperature and pressure conditions.
Here’s how AOx compares with the existing technologies:
- Injected AOP has a high operating cost, due to the need to continuously input expensive chemical reagents proportional to the quantity of contaminants to be removed; and the related labor.
- Unlike injection, AOx does not require input of expensive reagents, and can operate unattended.
- Catalytic AOP often needs salt to bring about a reaction, and may not be a real-time process.
- Unlike many other typical processes, AOx requires no salt or other mineral, and treatment can be continuous and real-time, depending on requirements.
- Irradiation AOP produces ozone, which by itself does not produce hydroxyl radical, the strongest oxidant used in water treatment.
- Unlike injection, AOx does not require input of expensive reagents, and can operate unattended. Unlike irradiation, AOx generates a wide range of ROS, including the all-important Hydroxyl Radical (OH•).
AOx is the effective technology for Advanced Oxidation Processing.
