This study aimed to investigate the potential use of microalgae Chlorella sorokiniana and Scenedesmus quadricauda for bioremediation olive mill wastewater (OMW), which is a major environmental issue waste product oil production. The investigated effects different dilutions (10% 50%) OMW on growth their ability remove phenolic component hydroxytyrosol (OH-Tyr) enhance antioxidant properties. res...

the removal performance of total poly phenols and orthodiphenols (o-diphenols) content in olive mill waste (omw) was investigated with a three stages cross flow laboratory scale rotating biological contactor (rbc) in the present study. due to high cod and other pollutant in the original omw, physico-chemical treatment was effected for cod and other pollutant reduction prior to biological treatm...

ÐThis paper introduces DISK, a distributed Java Virtual Machine for networks of heterogenous workstations. Several research issues are addressed. A novelty of the system is its object-based, multiple-writer memory consistency protocol (OMW). The correctness of the protocol and its Java compliance is demonstrated by comparing the nonoperational definitions of Release Consistency, the consistency...

A secondary treatment for olive mill wastewater coming from factories working with the two-phase olive oil production process (OMW-2) has been set-up on an industrial scale in an olive oil mill in the premises of Jaén (Spain). The secondary treatment comprises Fenton-like oxidation followed by flocculation-sedimentation and filtration through olive stones. In this work, performance modelization...

Wordnets play a central role in many natural language processing tasks. This paper introduces a multilingual editing system for the Open Multilingual Wordnet (OMW: Bond and Foster, 2013). Wordnet development, like most lexicographic tasks, is slow and expensive. Moving away from the original Princeton Wordnet (Fellbaum, 1998) development workflow, wordnet creation and expansion has increasingly...

Olive oil production generates large volumes of wastewater. These wastewaters are characterised by high chemical oxygen demand (COD), high content of microbial growth-inhibiting compounds such as phenolic compounds and tannins, and dark colour. The aim of this study was to investigate biodegradation of olive mill wastewater (OMW) by yeasts Trichosporon cutaneum and Geotrichum candidum. The yeas...

Abstract Phenolic compounds in olive mill wastewater (OMW) are considered an environmental threat due to their antimicrobial properties. Because of the metabolic versatility microalgae, a biotic removal these seems suitable approach. To investigate phenolic compounds, three microalgae species Chlorella vulgaris , Acutodesmus obliquus and Monoraphidium braunii were cultivated flasks under consta...

The main objective of this paper was the selection of promising bacterial strains to be used as potential tools to remove phenols in olive mill wastewater (OMW) or in other food wastes. Therefore, 12 OMW samples were analyzed and 119 isolates were collected. After a preliminary screening on a medium containing vanillic and cinnamic acids, three isolates were selected to evaluate their viability...

Background: Olive mill wastewater (OMW) is characterized by its high organic content and refractory compounds. The aim of this study was to evaluate compare the efficiency UV/O3 UV/ acetylacetone (UV/AcAc) processes for treatment pretreated OMW coagulation/microfiltration (C&M) process. Methods: In study, a laboratory-scale UV plug flow reactor with ancillary equipment fabricated. experimen...

Olive mill wastewater (OMW) produced from small units scattered in rural areas of Southern Europe is a major source of pollution of surface and subsurface water. In the present work, a treatment scheme based on physical separation methods is presented. The investigation was carried out using a pilot-plant unit equipped with ultrafiltration, nanofiltration, and reverse osmosis membranes. Approxi...
