In this work, concentration and recovery of high-added value phenolic compounds from two-phase olive-oil washing wastewater (OOWW) and parallel effluent treatment by a ‘green process’ based on novel weak-base ion exchange (IE) resins was addressed. The key operating input factors of the resin process for the treatment and valorization of OOWW were studied, optimized and further modelled. A Box-Behnken design was implemented and the obtained data were analyzed by ANOVA and interpreted by RSM methodology. The process was ulteriorly modelled by a second-grade quadratic fitting equation comprising the significant operating variables. The optimization of the IE process performance (20.3 °C, pH0 6.7 and 114 g/L Mresin) ensured up to 92.5% recovery of total phenols concentration. Moreover, the purified stream presented good quality (56.6–83.7 mg L−1 total phenols), following standard recommendations by the FAO. The obtained information would be of key importance for the scale-up of the proposed IE operation. Both the treatment and revalorization of OOWW would help implement a definite sustainable production process of olive-oil.}, organization = {Spanish Ministry of Economy and Competitiveness is acknowledged for having funded the project CTM2014-61105-JIN ‘Design and development of an integral process for revalorization and treatment of the effluents from olive oil industry’, as well as the University of Granada.}, publisher = {Elsevier}, keywords = {Olive-oil washing wastewater}, keywords = {Ion exchange}, keywords = {Resins}, keywords = {Phenolic compounds}, keywords = {Wastewater reclamation}, keywords = {Sustainability}, title = {Optimization and modeling of two-phase olive-oil washing wastewater integral treatment and phenolic compounds recovery by novel weak-base ion exchange resins}, doi = {https://doi.org/10.1016/j.seppur.2020.117084}, author = {Ochando Pulido, Javier Miguel and Vellido Pérez, José Antonio and González Hernández, Rubén and Martínez Férez, Antonio}, }
