Advanced Oxidation Processes (AOP)

Elimination of Active Substances by advanced oxidation technology

UV-oxidation, Photo-oxidation, Photo-Fenton or Photo-combined advanced ocidation processes for selectice degradation.

Advanced Oxidation Processes are known to eliminate all type of substances. For better economic properties Enviolet have developed special AOPs, to selectively destroy active substances (e.g. Active Pharmaceutical Ingredients, Pharmaceutically Active Compounds) dependant of the matrix. These substances can be toxic or undesired for various reasons.

The elimination of Pharmaceutically Active Compounds (PhAPs) have to be removed now in many countries below PNEC.

Enviolet UV-oxidation is very suitable and an approved advanced oxidation process for elimination of Pharmaceutically Active Compounds.

We have already treated solutions containing the following substances:

  • cyanides or organo-cyanides
  • aromatics, like benzene, phenol, toluene, PAH, biphenyl, and substitued products of these compounds
  • aminopolycarboxylates, like EDTA, DTPA, ...
  • phosphonates, herbizides on the base of phosphonates
  • active pharmaceutical substances (API) like hormones, cytostatics, atibiotics, ...
  • heterocyclics, like 1,4-dioxan, tetrahydrothiophene, ...
  • complex Structures, like pantopranzol, urapidil, ...

A dedeicated list of API treated with Enviolet APOs you find here.

Usually, the wastewater will be bioavailable after the uv-oxidation, or the bioavailability will at the least be strongly increased, or toxicity removed by photo-oxidation of toxic structures.
