ADOX® – Advanced Oxidation


Oxidative removal of pesticides and VOC

Ground and surface water are frequently subject to organic pollutants such as pesticides and chlorinated hydrocarbons. In order to prevent health risks strict legislation has been passed.

“ADOX” stands for “ADvanced Oxidation” and represents a process which leads to the mineralization of organic pollutants in water by OH-radical oxidation.

The main principle of the ADOX®- process is the combined use of ozone and hydrogen peroxide. Ozone is produced in an ozone generator from air or oxygen and is added to a partial stream by an injector or diffusers in the reactor. Hydrogen peroxide is dosed into the main treatment line.

Subsequently, a high percentage of the pollutants is mineralized in the reaction tank. In the ADOX®- process post-treatment is accomplished by biological activated carbon filtration.

The process applications include:

  • Ground water treatment for the removal of pesticides and chlorinated hydrocarbons.
  • Surface water treatment with conventional ozonation being supplemented by the efficient removal of pesticides or other organic pollutants.
  • Ground water remediation: involving the removal of pollutants such as chlorinated hydrocarbons, BTX and PAH.
