Photocatalytic Oxidative Treatment of Waste

Water contamined with Pharmaceutical Products

Pharmaceutical Micropolluants in Waste Water: 4 sources

- Hospitals

- Pharmaceutical Industries - Intensive animal livestocks - Domestic waste water

Elimination Processes of micropollutants in WWTP

Biological Treatment in WWTP <50% degradation

Reduction of micropollutant by

1) ADSORPTION ON SLUDGES 2) VOLATILISATION

3) BIODEGRADATION

Scheme of the suggested treatment

Biological Treatement Decantation 1 Biological Treatment Clarificator Finishing Treatment Ozone-UV-TiO₂ Active Carbon Sludges

European Water Directive

2013: diclofenac, 17alpha-ethinyl-estradiol, 17betaoestradiol added to the water directive watching list : Concentration and,toxicity data monitored at european scale.

2015: 3 macrolides antibiotics added: erythromycine, clarithromycine,azithromycine

Toxicity tests

Toxicity measurement of waste waters with daphnies Daphnia Magma and fluorescent

bacteria Vibrio fisherii
