“…The carotenoids content obtained from 100 g of fresh material was around 16 mg, within the range of the results reported by Rebecca et al (2014). OMW was found rich in phenols (1.26 g/L caffeic) in agreement with the observations of several authors (Belaqziz et al, 2016;El Yamani et al, 2017, 2019bArabi et al, 2018).…”

The activity of natural additives against the deterioration of virgin olive oil (VOO) in relation to storage time and conditions was examined. Thus, carotenoids and phenols previously extracted from carrot and olive mill wastewater, respectively, were added at 200 and 400 ppm to VOO and stored in clear and amber glass bottles at room temperatures during 120 days. The results showed that enriched VOO was largely influenced by the storage time, which resulted in a significant accumulation of hydrolysis and oxidation products. Storage conditions also affected considerably the enriched VOO. Dark glass bottles offered better protection against oxidative deterioration. The impact of both extracts on the oxidation status of examined VOO was significant and concentration-dependent. The natural additives markedly delayed the formation of hydroperoxides and conjugated dienes and trienes. Results from principal component analysis (PCA) showed that most of the variation was captured by the PC1 (89% of the total variance) which grouped samples in four categories according to storage times, each being divided into two clusters linked to storage conditions. Findings from this study revealed that natural additives could minimize VOO deterioration caused by storage time and conditions (light).

“…Similar results were obtained by Gamba et al (2005) and Rusan et al (2016). However, positive effects of OMW applications were reported for TOC (Lopez-Pineiro et al, 2011;Magdich et al, 2013) and for TN (Moraetis et al, 2011;Belaqziz et al, 2016). The variation in these results probably resulted from the different chemical characteristics of the OMWs used, type of soil, and crop involved.…”

“…As a result, high extractable P concentrations were determined only in soils amended with R-OMW while high extractable K concentrations were determined in soils amended with both R-OMW and treated OMWs (Table 3). Belaqziz et al (2016) found that after spreading untreated OMW in soil, the amounts of nutrients increased by 66% for P and 88% for K, respectively. Some authors (Chartzoulakis et al, 2006;Ayoub et al, 2014) considered the increased soil K levels as the most positive effect of OMW application on soil chemical properties.…”

This study was carried out to investigate the potential for the usability of treated olive mill wastewater (OMW) as an organic amendment in agricultural soils under Mediterranean climate conditions. OMW was treated by two different treatment processes as economical (E-OMW) and advanced (A-OMW). The treated OMWs and raw OMW (R-OMW) were applied to a loamy soil at a rate of 100 m 3 ha-1 year-1 for 2 years. Soils were sampled 15 days and about 5 months (at harvest) after OMW application for chemical and microbial analyses in each year. The total concentrations of N, P, Cu, Zn, and phenol of R-OMW decreased after both treatment processes while salinity (EC) and the total amounts of K, Na, and Ca increased. The applications of OMW caused changes in soil chemical (pH, EC, P ext , K ext) and microbial (microbial biomass-C (MB-C), microbial biomass-N (MB-N), basal soil respiration (BSR), N-mineralization (N-min)) characteristics (P < 0.05). In the second year of the experiment, initial samplings showed that the values of soil pH and EC increased significantly under all OMW applications compared to the control. High P ext concentrations were determined in soils amended with R-OMW, while there were high K ext concentrations in soils amended with the treated OMWs. The increases determined in MB-C and MB-N at all sampling times resulted in high MB-C/TOC and MB-N/TN ratios in soils amended with the treated OMWs. The wheat grain yield over the 2-year period showed that the application of the treated OMWs had a positive effect. It was determined that no negative effects occurred for either soil properties or wheat growth with the treated OMW applied at rates of up to 100 m 3 ha-1. The addition of treated OMW after removal of its phenolic components may be considered as a good option for evaluating this waste in countries where OMW causes serious environmental pollution.

“…They simultaneously impart an odor problem to the areas where such waste is stored and cause pollutant infiltration to groundwater and insect proliferation (Jarboui et al, 2010;Michael et al, 2014). Moreover, the direct spreading of raw OMW on agricultural lands has been thoroughly investigated during the last decades (Morisot, 1979;Rozzi and Malpeli, 1996;Marques, 2001;Di Bene et al, 2013;Barbera et al, 2014;Chaari et al, 2015;Belaqziz et al, 2016;Keren et al, 2017;Aharonov-Nadborny et al, 2018) and it has been proved that it represents an alternative inexpensive technique compared to filtration-percolation (Achak et al, 2009b) and coagulation-flocculation (Achak et al, 2008). Many researchers have studied the result of the OMW application on soil and crops (Mekki et al, 2006;Di Bene et al, 2013;Belaqziz et al, 2016) and they found that it exerts beneficial and negative effects.…”

Olive oil extraction processes generate three phases: Olive oil, solid residue (pomace) and aqueous liquor Olive Mill Wastewater (OMW). OMW causes serious environmental deteriorations such as coloring of natural waters, alteration of soil quality, phytotoxicity and odor nuisance. The direct discharge of this effluent into the soil bring various negative effects on the environment, due to its high load of organic matter and phenolic compounds. Coagulation, flocculation and their combination processes are among the most applied processes for wastewater treatment. The application of coagulation technique using mineral and inorganic polymeric coagulants and acid cracking is not always effective to reduce COD and phenolic compounds from OMW except lime. Although direct flocculation is a low treatment cost, use less chemical and produce less sludge, the efficiency of COD and phenolic compounds removal remain very low. Coagulationflocculation process is developed in order to enhance the removal efficiency of organic matter from OMW by optimizing the operating conditions. However, many studies showed that the combination of various cationic organic coagulant and flocculant agents did not show any significant decrease of COD and phenolic compounds except for lime combination. In the present review, recent research studies dealing with the application of coagulation/flocculation for removal of phenolic compounds and COD from OMW are presented and compared. Furthermore, the main factors that influence the selection between coagulation, direct flocculation and coagulation-flocculation are presented and the principal removal mechanisms are discussed.
