“…In recent years, adsorption has been reported as one of the most promising OMWW pretreatments in view of a further biological treatment, due to the high polyphenol removal efficiencies 11 or as a treatment before the use of OMWW for hydrogen photo-production. 12 Barbera et al 13 studied adsorption as the only treatment before OMWW application to a particular agricultural purpose. Thus, these authors achieved 95% polyphenols removal with 80 g L -1 of activated carbon.…”

BACKGROUND Fermentation brine from Spanish style green table olives processing (FTOP) is characterized by very high conductivity (around 88 mS cm‐1), high values of suspended solids (near 1300 mg L‐1), chemical oxygen demand (around 17 900 mg L‐1) and total phenols (1000 mg L‐1). In this work, fermentation brines have been exhaustively characterized and pH adjustment–sedimentation, coagulation–flocculation–sedimentation and adsorption with activated carbon have been evaluated. RESULTS AND CONCLUSIONS The pretreatment selection will depend on the final FTOP management. If no polyphenols elimination is required in view of a further recovery, the best pretreatment is pH adjustment to 9 plus sedimentation. The removal efficiencies achieved were 33.1% suspended solids, 82.5% turbidity and only 10.4% of polyphenols. However, if the final FTOP treatment was biological, the best pretreatment is adsorption with powder active carbon, because this pretreatment implies the maximum reduction of phenols in FTOP, which inhibit microorganism activity in the biological process. The maximum total phenols removal efficiency was 96% with 8 g L‐1 of BM8 powder activated carbon (21% soluble COD). © 2014 Society of Chemical Industry

“…Yet, great concerns have been raised regarding the adverse effects of OMW on and to seed development and germination (Aliotta, Fiorentino, Oliva, & Temussi, 2002;Aviani, Raviv, Hadar, Saadi, & Laor, 2009;Barbera, Maucieri, Ioppolo, Milani, & Cavallaro, 2014;Boz et al, 2009;Buchmann, Felten, et al, 2015;El Hadrami et al, 2004;Rusan, Albalasmeh, Zuraiqi, & Bashabsheh, 2015;Saadi, Laor, Raviv, & Medina, 2007;Saadi et al, 2013). Still, following land application, only short-term phytotoxic effects were mostly observed, lasting a few weeks (Piotrowska, Iamarino, Rao, & Gianfreda, 2006;Saadi et al, 2007;Saadi et al, 2013), although Mekki, Dhouib, Feki, and Sayadi (2008) detected increased concentrations of phenolic compounds at a depth of 1.2 m in a sandy soil 4 months after application and extracted a moderately phytotoxic residual phenolic fraction from the upper soil layer 1 year after application.…”

Annual spreading of olive mill wastewater over consecutive years: Effects on cultivated soils' physical properties

Several studies cautioned against potential negative effects of controlled olive mill wastewater (OMW) application on soil physical properties that could be associated with the possible adverse effects of K on soil structure stability. The objective of the study was to examine the effects of annual application of OMW over several years on selected physical properties of the upper soil layer (0-10 cm) and their link to exchangeable K levels. Two experimental field platforms were studied: field crops grown in a tilled clay soil (3 years of OMW application) and an olive orchard grown in a sandy-loam soil (5 years of OMW application). In the clay soil, OMW application did not affect organic carbon (OC) and only slightly increased exchangeable potassium percentage (EPP) from 3.3 in the control to~4.5 in the OMW-treated plots. In the sandy-loam soil, application of different rates of OMW resulted in an increase in both OC and EPP (>20) compared with the control (8). For both soils, addition of OMW improved aggregate stability; yet for the clay soil, the increase was not associated with changes in EPP or OC. In the sandy-loam soil, aggregate stability was positively correlated with OC and EPP. Soil hydraulic conductivity, tested for the sandyloam soil only, was not affected by OMW application. Overall, our study shows that consecutive 3 to 5 years of controlled OMW application in the range of 50-150 m 3 OMW ha −1 y −1 does not result in the deterioration of soil physical and hydraulic properties. reported a range of 5.5-12 dS m −1 for electric conductivity. In addition to the oil extraction process, the high variability in OMW properties was attributed to harvest date, irrigation level, cultivar type, and fruit water content (Aviani et al., 2012). Nonetheless, these unique characteristics of OMW prevent its direct discharge into domestic wastewater treatment plants (Laor et al., 2011;Rozzi & Malpei, 1996;Sayadi, Allouche, Jaoua, & Aloui, 2000 to the classic "wastewater treatment" approach, numerous studies advised the controlled spreading of OMW on cultivated soils as a viable recycling approach. It was further suggested that OMW could be considered as a useful, low-cost soil amendment and fertilizer (Chartzoulakis, Psarras, Moutsopoulou, & Stefanoudaki, 2010;Gargouri et al., 2013;Hanifi & El Hadrami, 2008;Laor et al., 2011;Tomati, Galli, Fiorelli, & Pasetti, 1996), although OMW application caused a drastic reduction in soil mineral-N indicating net N immobilization (Karpouzas et al., 2010). OMW showed its potential to serve as environmental friendly bio-herbicide (Boz, Dogan, & Albay, 2003;Boz, Ogüt, Kir, & Dogan, 2009), and finally, in regions having low soil organic matter (SOM) content and consequently low soil fertility, OMW can serve as a readily available organic matter (OM) source.Yet, great concerns have been raised regarding the adverse effects of OMW on and to seed development and germination (Aliotta, Fiorentino, Oliva, & Temussi, 2002;Aviani, Raviv, Hadar, Saadi, & Laor, 2009;Barbera, Maucieri, Iop...

“…Seed germination can be affected by different soil properties such as pH, salinity and the presence of toxic substances in the soil (Courtney & Mullen, 2009;Barbera et al, 2014). Changes in soil pH can modify seed germination of different plants (Shoemakerl & Carlson, 1990;Deska et al, 2011;Barbera et al, 2014;Courtney & Mullen, 2009). According to these authors, seed germination is lower under low and high pH values than under intermediate pH values.…”

Cu pollution and erosion pose an important risk of degradation in vineyard devoted soils. Therefore, minimizing harmful effects of Cu in the soil and avoiding erosion are important challenges in vineyard soil management. The addition of low cost bio‐adsorbents to the soil which decreased Cu bioavailability in soil and/or increased cover crops development may be an important management practice for soil stabilization in vineyards. This study investigated the effect on Lolium perenne performance because of crushed mussel shell (CMS) amendment in an acid Cu‐polluted vineyard soil. Quadruplicate samples of a Cu polluted soil were amended with 4 doses (0, 6, 24 and 48 g kg−1) of CMS by in lab pots, where L. perenne was sowed and incubated for 51 days. The soil pH, as well as Cu bioavailability and exchangeable Cu, was analysed. The effect of CMS on L. perenne response was measured using plant germination, plant growth and Cu uptake. The plant growth was assessed in both roots and shoots by measuring length and biomass. Cu uptake by roots and shoots was also determined. The CMS amendment on the acid vineyard soil increased the pH and reduced the bioavailable Cu concentration. Moreover, shoot and root growth increased for low and intermediate CMS doses, and decreased for higher doses. The increase in plant growth corresponded with increases in soil pH up to 7 · 0, whereas the highest mussel shell dose caused a pH increase over the neutrality (7 · 8). The CMS amendment decreased Cu uptake by both, roots and shoots, and it was highly correlated with changes in Cu bioavailability in the soil. The CMS amendment on a Cu‐polluted acid soil presented positive effects on Cu immobilization and L. perenne growth. However, mussel shell application must be performed carefully, taking into account that high doses can lead to decreases on plant growth. Copyright © 2016 John Wiley & Sons, Ltd.
