Short-term effects in soil microbial community following agronomic application of olive mill wastewaters in a field of olive trees

Use of ultrasonic energy for enhancing the dyeing performances of polyamide fibers with olive vegetable water

“…Effect of the Dye Bath pH The effect of the dye bath pH on the dyeability of polyamide fabrics with the olive vegetable water was conducted at different pH (2)(3)(4)(5)(6)(7)(8). As shown in Figure 5, the color yield (K/S) of the dyed fabrics seemed to be inversely proportional with the pH of the dye bath.…”

“…Dyeing Procedures Polyamide fabric was dyed at different pH values (2)(3)(4)(5)(6)(7)(8), at different temperatures (50-100 o C), and for different durations (15-120 min). Throughout the manuscript, conventional heating is abbreviated to (CH) and ultrasonic treatment is abbreviated to (US).…”

“…However, in most of cases, the proposed technologies were not adequate to provide an economically acceptable final product, as the treated olive vegetable water remained toxic and/or the proposed methods had been proven to be unrealistic [6].…”

Comparative experiments to assess the performance of an innovative horizontal centrifuge working in a continuous olive oil plant

“…The amount of contaminated wastewater produced by this process is correspondingly high. The quantities of wastewater proved to be an ecological problem (Mechri et al, 2007;Roig, Cayuela, & Sanchez-Monedero, 2006). Additionally, due to the large amount of water added to the process, a considerable reduction in the natural antioxidant in the resulting olive oil was observed (Di Giovacchino, Costantini, Serraiocco, Surricchio, & Basti, 2001;Kalogeropoulos et al, 2014).…”

Rhizosphere dynamics during phytoremediation of olive mill wastewater

“…Based on these premises, an experimental campaign was carried out to assess the feasibility of tree-based phytoremediation for OMW treatment, by testing the tolerance of different plant species. Previous works reported the impact on soil properties of OMW spreading on cultivated land (Mechri et al, 2007;Karpouzas et al, 2009), but, for the first time, in this study, during-and post-treatment changes in both soil biochemistry and bacterial and filamentous fungal communities were investigated at the rhizosphere level and associated with tree tolerance to OMW. In line with the seasonal course of OMW production, five perennial plants, Salix sp., Quercus ilex L., Laurus nobilis L., Pinus mugo Turra and Cupressus sempervirens L., were subjected to a six-month treatment cycle with 100% or 50% OMW.…”
