Project Idea: Waste Water Treatment

The pharmaceutical products (PPs) are introduced into the environment by domestic or hospital waste waters and they are currently poorly removed by classical biological waste water treatment plants. Yield of removal is about 20 to 50% depending on molecules polarity and hydrophobicity. Thanks to better sensibility of detection methods, traces of these PPs have been found in waste waters, source waters and even in drinking waters.

In the case of decontamination of waste waters, the use of (i) ozone which increases the amount of free radicals (OH and O*) in water, and of (ii) heterogeneous photocatalysis illuminated under UV light which involves pollutants adsorption on the photocatalyst surface and the oxidative degradation of these adsorbed pollutants, ideally into CO2, H2O and other products resulting from complete oxidation, is a promising solution.

The objective of this project is to determine operational processes for advanced oxidative treatment of waste waters contaminated with PPs. This is a finishing  physico-chemical process that has to be placed after a classical biological treatment in existing waste water treatment plants (domestic, industrial or hospital).

Profile of additional Partners:

  • Research centre active in water treatment
  • Research centre active in photocatalyse
  • Partners for scaling-up of ozone-UV photocatalytic technology
  • Partners for continuous tests in WWTP or in pharmaceutical companies
