On-line hydrocarbons detection in wastewater treatment plant

Monitoring of hydrocarbon pollutants at the entrance of wastewater treatment plants is imperative for keeping them in good working order. The systems of detection existing on the marketplace are firstly analysed in order to understand why they are not an effective solution to the problem. The needed characteristics of an acceptable system follows from this analysis. A study of the different methods applicable to the distinction of hydrocarbon/water allowed one to highlight the attractive method of fluorescence. The main originality of this paper is the transposition of this method to the problem of concern. We conclude by the validation of our method through an in-situ preliminary test.
