MiPro eco3 plus advanced oxidation process (AOP)
- Suitable for various types of organic and inorganic micropollutants and other persistent substances
- Combines both Xylem’s Wedeco UV and Ozone systems with H2O2 dosing unit
- Residual ozone destruction system
Why Advanced Oxidation Process?
Water utilities are reporting a rising trend worldwide as far as problematic micropollutions in water resources are concerned. Traces of organic / inorganic pollutants like NDMA, MTBE, 1.4 Dioxan, and EDC are often found in ground and surface water.
Industrialization, intensive agriculture, as well as medical provisions for humans, all have contributed to the increase of contaminations. Once these micropollutants enter the human food chain via drinking water there is a long term risk to health, as well as human or animal genetic material. Traditional treatment methods are no longer sufficient to guarantee complete removal of these contaminants.
Increased pollutants in drinking water can also be attributed to climate and demographic changes as well. As a consequence, there is a higher risk of water scarcity and thus there will be an increasing demand for direct or indirect reuse of wastewater for drinking water purposes.
The Advanced Oxidation Process (AOP) is the ideal approach for removing these new types of water contaminations. AOP is the combination of two or more processes to generate hydroxyl radicals (OH radicals) or to increase the number of them. The OH radicals contribute to the oxidation of undesirable substances. Compared to other oxidants, the OH radical has a considerably higher oxidation potential.
Once hydroxyl radicals have formed in water, they immediately react to virtually all existing oxidizable substances. The high degradation performance and the quick reaction kinetics of this process are the formula for success when it comes to eliminating numerous persistent contaminants.
The best available technology
Ideally, contaminated water should always be treated using the most appropriate and efficient process available.
Xylem’s Wedeco MiPro eco3 plus AOP system is comprised of both a Wedeco UV and ozone system and a H2O2 dosing unit. The system is an injection / reaction unit and includes a residual ozone destruction system.
