Olive mill wastewater (OMW) was exposed to Fenton treatment and subjected to post Fenton coagulation/flocculation using lime. Several tests were performed for different R = H2O2/COD ratios, from 0.25 to 3.0, promoting the gradual addition of H2O2 and Fe2+, with the original condition of a pH = 3.5 and maintaining a constant relationship H2O2/Fe2+ = 15. A maximum reduction of COD of 96.8% was ob...

In recent years, the study of membrane processes for recovery valuable phenolic compounds from olive mill wastewater (OMW) has been intensified. The selected OMW pH ultrafiltration is one variables affecting productivity, selectivity and fouling. An in-depth characterization fouling was performed 150 kDa ceramic tubular selected. At three tested (2, 6 9), a high retention suspended matter 98% a...

Over the last decade, two-phase centrifugation system for olive-oil extraction has become dominant in Slovenia. There are many suggestions exploitation of OMW, but among suggested methods, direct spreading on agricultural land appears to be operationally simple and economically feasible As there is little information available about OMW produced northern Mediterranean regions, aim was determine...

Olive oil production is one of the important industrial sectors within agro-food framework Mediterranean region, economically to people working in this sector, although there also a threat environment due residues. The main wastes olive extraction process are mill wastewater (OMW) and husks which require proper treatment before dismissal. In research work, goal introduce grey relational analysi...

Abstract The Mediterranean area concentrates the world’s largest production of olive oil. oil industry represents, in this basin, one leading sectors agri-food economy. Olive mill water (OMW) is principal waste effluent produced by industry. Due to its high pollution load, aqueous by-product cannot be directly disposed domestic wastewater treatment plants (especially those with a biological uni...

Abstract Olive oil mill wastewater (OMW), a by-product of the olive industry, each year is generated millions tons all over Mediterranean countries. Uncontrolled disposal OMW leads to massive environmental problems including soil and water pollution. In this experimental study, was used partly replace clean for getting prepared formaldehyde solution. Then, phenol solutions were synthesized unde...

Acidogenic fermentation of wastes produces volatile fatty acid (VFA)-rich streams that can be used as low-cost carbon sources for polyhydroxyalkanoate (PHA) production. In this study, an inoculum collected from anaerobic reactor a municipal WWTP was conditioned to suppress methanogenic activity. The heat-shock conditioning method the proved more efficient than and alkaline methods methanogens i...

Olive oil is one excellence of the Italian food industry: around 300 kt yr−1 are produced, creating roughly same amount olive mill wastewater (OMW) to be disposed of. The present work describes a process exploit OMW by converting its organic compounds valuable gaseous biofuel. A sample was characterized (COD, TOC, solids, and polyphenols) submitted membrane filtration tests concentrate compound...
