Liquid Wastes

The olive oil production countries are currently faced with the major problem of dealing with olive oil mill wastewater. Effective treatment of these organic liquid wastes (katsigaros) has not been proposed yet. The common practice followed the last fifteen years in the island of Crete includes the creation of open wastewater evaporation ponds. The present work studies the sorption of organic agents, more specifically the phenolic compounds, in various lithology rocks. Three different samples were tested including Neogene marl-calcareous marl from Platania/Kissamou (PLA) area, schistolithic rock from Sarakina/Selinou (SAR) area and Neogene marl-siliceous (diatomite) marl successions from Basilies/Heraklion (VAS). The organic liquid wastes affect differently the PH and electrical conductivity from the studied rocks with different mineralogical composition. Rocks containing lllite show a significant adsorption of the phenolic compounds. Similar behavior is observed for the Neogene marl-siliceous (diatomite) samples, while the schistolithic rock show the lowest adsorption. The katsigaros dissolve the calcite and iron minerals and increases the CaO and Fe203 in the liquid waste.

Abstract This study aimed to the determination of antioxidant, anti-inflammatory, and anticoagulant activities of phenolic compounds present in olive oil mill wastewater (OMW) issue from the cold extraction of olive oil from Khenchela eastern of Algeria.After polyphenols extraction, a quantity and quality analysis by LC-MS was made. The LC-MS (liquid chromatography–mass spectrometry)results were revealed the presence of 20 phenolic compounds in theextract of OMW which were: (quinic acid, gallic acid, protocatechuic acid, caffeic acid, p-coumaric acid, rutin, transfrolic acid, hyperoside (quercetin-3-o-galactoside), luteolin-7-o-glucoside, naringin, 4.5-di-caffeoyquinic acid, quercetrin(quercetin-3-o-rhamonosid), apegenin-7-o-glucoside, salviolinic acid, kampherol, quercetin, naringenin, apegenin,cirsiliol, and cirsilineol). The results of antioxidant activity with DPPH(2,2-diphenyl-1-picrylhydrazyl), ABTS+ (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid), and FRAP (ferric reducing ability of plasma)showed that the IC50(half-maximal inhibitory concentration) were(9.62 ± 0.28µg/mL, 7.10 ± 0.11µg/mL and 3.59 ± 0.24µg/mL)respectively. The extract of OMW was found to exhibit the highestinhibitory effectanti-inflammatory activity usinginhibition of protein denaturation(IPD) and membrane stabilizing potential (MSP) tests (80.46 ± 3.81; 87.43 ± 0.66 µg/mL) more than the standard used. In addition, the extract had the best anticoagulation activity in the endogenous and exogenous pathways (44.77 ± 0.25s; 15.84 ± 0.12s). Based on these results, it is right to conclude that OMW is an important source of natural phenolic compounds that have important antioxidant, anti-inflammatory, and anticoagulant activities.

Olive Mill

Olive oil is one of the most widely used oils in the world with economic importance for many countries. Olive oil extraction generates large amounts of solid (cake) and liquid waste (olive mill wastewater, OMW), which pose a chronic environmental problem due to their disposal of the produced wastes on the landfill and water recipients. Thus, the research community is in search of techniques, individually or in combination, in order to detoxify waste. The common treatment methods belong to a one-dimensional waste treatment approach, which is depollution. A practical way to overcome the financial obstacle of depollution is to develop treatment schemes that combine depollution with recovery of valuable ingredients, such as phenolics. The toxicity of this waste is mainly due to the high concentration of phenolic compounds, which, however, have strong antioxidant activity, turning OMW into an economical raw material for the recovery of bioactive compounds. Adsorption is generally considered to be the most effective and low-cost method for the removal of phenolics. So far, few studies have been carried out using sorbents for the removal of phenolics from OMW. However, the relatively high initial cost and the need for a costly regeneration system render common sorbents less economically viable. Thus, many researchers have focused their efforts on optimizing adsorption process by development of novel, low-cost adsorbents with high adsorptive capacity, originating from food industry byproducts (biosorbents). The objective of this work is to provide a comprehensive summary of the biosorbents used for OMW management.
