The increment in world population has led to the increasing demands for fish supply as principal source of animal protein that represents about 17% consumption globally. aquaculture industry expanding remarkably but limited fishmeal and oil which known important ingredients feed seeking alternative sources their replacement aquafeed formulation. Many potential cheaper derived from vegetable oil...

Olive oil and pig productions are important industries in Portugal that generate large volumes of wastewater with high organic load toxicity, raising environmental concerns. The principal objective this study is to energetically valorize these effluents—piggery effluent olive mill wastewater—through the anaerobic digestion biogas/methane production, by means complementarity concept. Several mix...

Wastewater from the olive oil industry is an environmental problem which growing in Mediterranean region. Presence of phenolic compounds and high organic matter load are characteristics this effluent that make it difficult to treat. In study, applicability sulfate radical based advanced oxidation processes (SRbAOPs), using peroxymonosulfate (PMS) as oxidant, was evaluated treatment synthetic mi...

Wastewaters from the olive oil industry are a regional environmental problem. Their phenolic content provides inherent toxicity, which reduces treatment potential of conventional biological systems. In this study, Sulfate Radical based Advanced Oxidation Processes (SRbAOPs) compared with advanced oxidation processes (namely Fenton’s peroxidation) as depuration alternative. Synthetic mill wastew...

Abstract This work aimed at treating OMW by developing an environmentally friendly and cost-effective media capable of removing phenolic compounds upon the interaction between magnetic nanoparticles sorbent material such as zeolite. Magnetite (Fe 3 O 4 ) goethite (FeO(OH)) were prepared using microemulsion method dimethylene-1,2-bis (dodecyl dimethyl ammonium bromide) (CTAB) a surfactant. The h...

In our earlier studies, we proposed a method for the simultaneous recovery of dietary fibers and phenols from olive mill wastewater (OMW) in two different streams: (i) an alcohol insoluble residue (AIR) rich in dietary fibers and (ii) an ethanolic liquid rich in phenols. The ethanolic liquid has been proposed for a direct application in the beverage industry, i.e. as an additive to produce soft...

A treatment train for the remediation of a raw olive mill wastewater (OMW) was investigated, aiming to comply with emission limit values (ELVs) direct discharge into water bodies. The following stages were proposed: (i) pre-treatment (filtration and sedimentation), (ii) coagulation, (iii) biological oxidation, (iv) advanced oxidation process (AOP). Under best-operating conditions coagulation (0...
