Abstract:

© 2018 Published by Elsevier B.V. In the present study the analysis of the physico-chemical parameters of the collected TWW shows the BOD, COD, COT, Cl-, NO3, NO2, suspended matter, organic matter, turbidity and conductivity were in accordance with the required Tunisian legislations. In the same occurrence, the ICP-MS and the UPLC-MS/MS analysis show that TWW were devoid of different toxic metals and antibiotics, respectively. We opted to reuse of the TWW in the irrigation of young olive trees of two varieties: Olea europaea L. cv. Chetoui and Olea europaea L. cv. Chemlali which receiving 1 "L/week of TWW during five months. Results show that dry roots weight and the content of chlorophyll a in 'Chetoui' variety increased significantly (p<0.05) when compared to the control group. On the same way, significantly increase of leaf area, dry roots and leaves weights was observed in 'Chemlali' variety treated with TWW.
