Many reclamation treatments as well as integrated processes for the purification of olive mill wastewaters (OMW) have already been proposed and developed but not led to completely satisfactory results, principally due to complexity or cost-ineffectiveness. The olive oil industry in its current status, composed of little and dispersed factories, cannot stand such high costs. Moreover, these trea...

Diverse vegetable oils are extracted from oleagenic trees and plants all over the world. In particular, olive oil represents a strategic socio-economic branch in Mediterranean countries. These countries use either two or three-phase extraction systems. this work, we focus on by-products extraction, which liquid mill wastewater (OMW) solid pomace (OMP) rejected evaporative ponds. The disposal of...

Olive mill wastewater (OMW) is one of the most environmentally concerning food processing effluents due to its phytotoxicity. Recently, several bioactive compounds with potential applications in food, pharmaceutical, and agricultural industries have been identified OMW. This study aimed compare, for first time, physico-chemical characteristics biological activity OMW obtained by two different t...

This study elucidated the impact of sewage-sludge (SS) and olive-mill-waste (OMW) biochar amendments to soil using tomatoes as a test crop. Four treatments were evaluated: “control” with no amendment, two SS addition 10 t/ha 25 t/ha, respectively, an OMW treatment t/ha. Higher yields observed in both treatments, providing evidence that acts plant bio-stimulant. Biochar application had positive ...

Pleurotus pulmonarius mushroom was cultivated on liquid cultures with olive mill wastewaters (OMWs) of initial phenolic compound concentrations 0 (control), 1, 2 and 3 g/L glucose at 40 60 g/L. The ability the fungus to grow media containing toxic compounds enriched assessed through biomass production, consumption, polysaccharide (IPS) accumulation total cellular lipids biosynthesis, while (TPC...

The present paper focuses on a largely unexplored field of landfill-site valorization in combination with the construction and operation of a centralized olive mill wastewater (OMW) treatment facility. The latter consists of a wastewater storage lagoon, a compact anaerobic digester operated all year round and a landfill-based final disposal system. Key elements for process design, such as waste...

Different amounts of Ca(OH)2 were added in 2 L beakers containing 1 L of olive mill wastewater (OMW). The mixture was stirred for 45 min and left to settle. Wastewater analysis was used in order to determine the effect of the different amounts of calcium hydroxide in the treating process, three days after the application. The Odor Detection Threshold was used for determining the effect of the t...

Mining activities frequently leave a legacy of residues that remain in the area for long periods causing pollution surroundings. We studied on 100 year-old mine, behavior potentially toxic elements (PTEs) and their ecotoxicological impact activity diversity microorganisms. The PTEs contamination assessment allowed classification materials as highly (reference- contaminated-samples) very pollute...

Nowadays, population growth is likely to lead a wide variety of biomass wastes generation from the diversified human, industrial, and agricultural activities. Anaerobic digestion mostly applied manage mitigate huge spectrum environmental damages. This paper aims enhance anaerobic efficiency multicomponent substrates, using mixture waste activated sludge (WAS), olive mill wastewater (OMW), cattl...

Managing olive mill wastewater (OMW) is a major environmental problem. We followed two methods for OMW bioremediation: one with the white-rot fungus Pleurotus ostreatus alone and plus microalga Chlorella vulgaris. To evaluate potential use of both final products as soil amendments, in pot experiment, we applied treated to cultivated Lactuca sativa, studied their short-term effects on nematode c...
