Analysis of Real-Time Monitoring Of Trace Contaminants in a Pilot-Scale Treatment System and Calculation of UV Dose Using Hydrogen Peroxide Actinometry

The use of two online sensors, the S::CAN and the FLD, was used to evaluate the treatment of synthetic wastewater by UV/H₂O₂ advanced oxidation. The UV dose and intensity for the flow through reactor was also determined using H₂O₂ actinometry. The total power of the lamps in the reactor was determined to be 139 W which, with the absorbance of the water, produced a UV dose of 39.4 mJ/cm². It was determined that the S::CAN was unable to differentiate between treatment of a particular water, however it could differentiate between different test waters. The FLD was very sensitive and was able to detect minute variations in treatment of the test water
