10-18: Oil-In-Water UV Fluorescence Sensor In Cooling Tower And Other

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.
