Advanced Oxidation Processes for Wastewater Treatment

AOP (Advanced Oxidation Process) Systems

Complex problems require radical solutions

State-of-the-art AOP systems use or combine two or more oxidizing agents to create hydroxyl radicals, the ultimate oxidant for elimination of organic pollutants. We design and manufacture the widest range of ultraviolet, ozone and AOP systems incorporating the most sophisticated electronics and lamp technologies available to meet the needs of industrial and municipal customers. Our experts partner with customers to achieve the best overall answer to meet treatment requirements safely and economically.

How Advanced Oxidation Processes Work

AOP are aqueous phase oxidation methods consisting of highly reactive species used in the oxidative destruction of target pollutants. AOP creates a more powerful and less selective secondary oxidant, hydroxyl radicals, in the water.? This secondary oxidant can cause the oxidation of most organic compounds until they are fully mineralized as carbon dioxide and water. The hydroxyl radical has a much higher oxidation potential than ozone or hydrogen peroxide and usually reacts at least one million times faster, thus leading to a smaller contact time and footprint.

Applications

Municipal & Industrial Water Management

Due to industrial and demographic pressures, the use of AOP��s in water treatment is expanding for a number of critical users including the oxidation or removal of:

Industrial chemicals
Pharmaceuticals
Endocrine Disrupting Compounds (EDC��s)
Personal Care Products (PCP��s)
Pesticides
Toxic compounds
Odor, color and taste
Pathogens
Persistent Organic matter

These contaminants are known threat s for aquatic ecosystems and human health and have become a major issue for water utilities around the world.

Current treatment practices in existing wastewater plants struggle to eliminate these pollutants and meet current and future regulations. AOPs, thanks to their high oxidation potentials, have proved to be an efficient solution for the removal of these persistent organics.
