Advaced Oxidation Processes (AOP) (  ozon/UV, ozon/H2O2, UV/H2O2)

LifeOX® state–of–the–art AOP equipment developed by LIFETECH exploits three proven water treatment technologies – ozone, low pressure UV or medium pressure UV and hydrogen peroxide to create OH-radicals. OH-radicals have much higher oxidation potential than ozone or hydrogen peroxide itself. OH-radicals react at least 1 milion times faster than ozone. Thanks to this extremely fast disinfection and oxidation, disinfection stages take up tremendously less space than standard ozone technology.

advantages and disadvantages of AOP Technology

Best Available Technology for water treatment

Highest oxidation power (oxidation potential) out of all the technologies

Removal of very resistant substances

Significantly smaller space requirements than ozone technology

High reaction speed, thus reaction tanks significantly smaller

More complicated installation

Higher purchase price

Urban wastewaters are increasingly contaminated with organic substances such as biocides, personal care products (PCP’s), fuel additives, endocrine disruptors (EDC’s), pharmaceutical products, fuel additives, and other emerging pollutants, that cannot be removed by standardly used technologies. AOPs have proved to be the most efficient solution for the removal of those toxic and persistent compounds such as: carbamazepine, ibuprofene, hormones, geosmin, mib (2-methylisoborneol), 1.4 dioxane, mtbe (methyl tertiary-butyl ether), ndma (n-nitroso-dimethylamine), atrazine, diuron, diclofenac,… LifeOX®-M technology is also the best available technology for the removal of combined chlorine from pool water. Combined chlorine is responsible for red eyes, dry skin and asthma of swimmers, corrosion of pool hall and the typical pool smell.

High oxidation potential of ozone can be greatly enhanced by its combination with UV treatment or hydrogen peroxide dosing, i.e. by an approach known as Advanced Oxidation or Ultraviolet Oxidation. LIFETECH uses both processes and supplies its own LifeOX® technology based on optimized synergic action of ozone and UV radiation.

The Advanced Oxidation Process (AOP) is the best water treatment technology now available. AOP is based on creating OH-radicals in water. Those OH-radicals have considerably higher oxidation potential compared to other oxidants for water treatment. What it means is that OH-radicals (thus AOP technology) are able to oxidize particles in water much faster and more efficiently. See the graph below for comparison.

OH-radicals have higher oxidation potential than hydrogen peroxide or ozone. The higher the oxidation potential, the better the disinfection and purification.

As seen in the figure below, when dissolved ozone (1) is irradiated by UV radiation in a UV reactor (2), then OH- radicals are created. Lifetime of OH-radicals is extremely short, the entire treatment process takes place inside of the UV reactor within miliseconds. Treated water (3) is then free of OH-radicals.

Traditional use of ozone or UV technology alone cannot guarantee complete removal of water micropollutants. The AOP process is ideal for their removal.

We enhanced the high oxidation potential of ozone and UV radiation beyond its limits. By making them work together synergically it is now possible to experience water quality of the future. LifeOX® is a unique AOP technology developed by LIFETECH.
