In order to simplify and accelerate the analyses of oil and grease in industrial waters, particularly used in cooling water in heat exchangers, a UV-fluorescent sensor sensitive to polycyclic aromatic hydrocarbons (PAH) being part of refined oil products was tested.  The testing was also conducted in several applications involving wastewater treatment and confirmed a relationship between oil-in-water concentration and content of the PAH.  While qualitative response is always strong and fast, OIW quantification can be achieved in samples containing stable content and type of oils.
