WEDECO, a Xylem brand
Why Advanced Oxidation Processes?
The use of an Advanced Oxidation Process (AOP) is an ideal approach to treat new kinds of persistent water contaminants. AOP is the combination of two or more processes to generate or increase the number of hydroxyl radicals (OH radicals). The OH radicals contribute to the oxidation of undesirable substances and have a considerably higher oxidation potential compared to other oxidants. Water utilities are reporting a worldwide rising trend in the presence of micropollutants in water... (read more)
