Description

The efficiency of the CWPO process driven by an Al/Fe-PILC clay catalyst was evaluated in the removal of dissolved natural organic matter from different real water supplies: either raw or partially-treated water at several stages of drinking water urban plants (three points at three different UPs), or drinking water rural plants (five RPs) were processed at natural and varied conditions of pH, temperature, and environmental pressure. The optimal conditions of the CWPO reaction were refined taking into account the presence of well-known scavenging, inorganic anions in real surface water supplies. Besides, the catalyst preparation from technical-grade reagents was assessed. The catalytic results are analyzed in terms of DOC and total nitrogen mineralization, color removal (456 nm), the evolution of SUVA254, and efficiency of H2O2 consumption, but also taking into account the influence of the physicochemical properties displayed by the input natural water samples (pH, temperature, apparent color, UV254 absorbance, turbidity, alkalinity, and contents of main inorganic anions) on the catalytic performance using statistical tools. This dataset displays all the raw and treated data regarding the catalytic wet peroxide oxidation of dissolved Natural Organic Matter (NOM) in all, a synthetic surrogate of NOM, and several real surface water samples collected at urban and rural drinking water treatment plants (DWTPs). The catalytic reactions were performed in the presence of Al/Fe-PILC clay catalysts. The data here shown consists of: 1. Physicochemical properties of the Al/Fe-PILC clay catalysts used. 2. Identification of the real surface water samples studied. 3. Average standard deviations for all catalytic responses as a function of the type of water and DWTP, as the quality control of the catalytic data. 4. Characteristics of the statistical optimization of the CWPO degradation of NOM and the experimental data obtained (Factors, levels, covariates). 5. Multiple regression analysis measuring the correlation of the physicochemical properties of the input real water samples over every catalytic response. 6. Final average DOC values for the effluents of every stage of treatment at DWTPs and the CWPO treatment. 7. Current stages of treatment at the urban conventional DWTPs. 8. Composition of the synthetic surrogate of dissolved NOM employed for the statistical optimization of the CWPO catalytic degradation. 9. Estimated response surface plots for every catalytic response and Desirability-based multiresponse surface which allowed establishing the optimal reaction conditions. 10. Measured color removal in urban and rural plants through CWPO treatment. 11. Measured consumption of hydrogen peroxide at urban and rural plants through CWPO treatment. 12. Measured nitrogen removal through CWPO treatment. 13. pHpzc of the Al/Fe-PILC clay catalyst.
