Synergy of Alum and Chlorine Dioxide for Curbing Disinfection Byproduct Formation Potential at Central Arkansas Water
… In this study, fluorescence parallel factor (PARAFAC) analysis was combined with free chlorine simulated distribution system (SDS) tests and DBP formation potential (DBPFP) tests to study the benefit of chlorine dioxide primary disinfection (CDPD) with alum coagulation. Of the DBPs screened, …

Dissolved organic material in groundwater and application of fluorescence spectroscopy coupled with EEM PARAFAC models as a means of site characterisation
… up to 3,500% during initial abstraction. Analysis of excitation emission matrices (EEMs) and absorption data demonstrated that the increased DOC and an increase in relative molecular weight of dissolved organic matter (DOM) was likely due to biofilm shearing. The fourth stage split a set …

Fluorescence Based Approach to Drinking Water Treatment Plant Natural Organic Matter (NOM) Characterization, Treatment, and Management
… before and after coagulation. Parallel factor analysis (PARAFAC) was applied in order to generate independent models on different subsets of each drinking water treatment plant (DWTP) data set: (i) raw water, (ii) treated water, (iii) composite data set (i.e., raw and treated water), and (iv) …
