AB This study has assessed the usefulness of excitation-emission matrix fluorescence (EEMF) as a fast and simpleanalytical technique to track changes in dissolved organic matter (DOM) during the sequence of treatment inwastewater treatment plants (WWTPs). Three different industrial wastewaters and treatment plants have beenstudied in this work: an industrial park wastewater treated in an independent line at the Burgos WWTP (Spain), afood industry wastewater (crisps and snacks manufacturing) that was treated in a MBR (Membrane BiologicalReactor) pilot plant (University of Burgos) and a municipal landfill leachate treated in a physicochemicaltreatment plant within the same landfill.Removal percentages for the wastewater organic matter at each stage of the treatment plants were successfullyobtained by monitoring the main fluorescence peaks: protein-like peaks (tryptophan-like peaks T1, T2 andtyrosine-like peaks B1, B2), humic-like peaks (fulvic-like peak A and humic-like peak C) and microbially-derivedpeak M. Therefore, EEMF readily allows the assessment of the reactivity of the different types of organic mattertowards specific treatments, such as clarification, biodegradation, filtration, etc. Among the wastewaters studied,the food industry wastewater exhibited the greater diversity of fluorescence peaks (B1, B2, T1, T2, A1, A2 and M)whereas the landfill leachate only showed the presence of humic substances (mainly humic-like peak C). Thisstudy has demonstrated that EEMF is a useful and user-friendly technique to monitor the performance ofwastewater treatment plants for organic matter removal, allowing a rapid response to potential problems in thetreatment.
