Abstract

This dataset reports the data relative to a study of polyuphenol separation from olive mill wastewater. The goals of this study were (i) to compare two anion ion exchange resins (IRA958 Cl and IRA67) and a non-ionic resin (XAD16) in terms of phenolic compounds adsorption capacity from olive mill wastewater, and (ii) to compare the adsorption capacity of the best resin on columns of different length. The ion exchange resins proved less performant than non-ionic XAD16 in terms of resin utilization efficiency (20% versus 43%) and phenolic compounds/COD enrichment factor (1.0 versus 2.5). The addition of volatile fatty acids did not hinder phenolic compounds adsorption on either resin, suggesting a non-competitive adsorption mechanism. A pH increase from 4.9 to 7.2 did not affect the result of this comparison. For the best performing resin (XAD16), an increase in column length from 0.5 to 1.8 m determined an increase in resin utilization efficiency (from 12% to 43%), resin productivity (from 3.4 to 7.6 gsorbed phenolics/kgresin) and phenolics/COD enrichment factor (from 1.2 to 2.5). An axial dispersion model with non-equilibrium adsorption accurately interpreted the phenolic compounds and COD experimental curves.
