Bioremediation of olive mill wastewater

International Biodeterioration & Biodegradation, 2008
Abstract The vast majority of olive oil production (>98%) occurs in the Mediterranean region, utilizing a tremendous volume of water (10–30 million m 3 ) in an area of the world in which water resources are limited. Treatment and reuse of olive mill wastewater (OMWW) presents significant challenges both due to the nature of olive oil production ...

Thermochemical treatment of olive mill solid waste and olive mill wastewater

Journal of Thermal Analysis and Calorimetry, 2015
In olive-oil-producing countries, large amounts of waste material are generated as by-product for which there is no ready use and in some cases may have a negative value because of the cost of disposal. Most of these countries depend on fossil fuels for their energy uses, and olive mill wastes can be used to supplement such energy sources using ...

New secoiridoid from olive mill wastewater

Natural Product Research, 2011
A new secoiridoid, olenoside A (1a) and its known epimer olenoside B (1b), were isolated from olive mill wastewater as a mixture of two isomers. Their structures, 1-methyl-7-oxo-6,6a,8,8a-tetrahydro-1H,3H-pyrano[3,4-c]pyran-4-carboxylic acid methyl ester, were determined by spectroscopic methods including 2-D NMR. The structure of major compound 1a was

Fertilizers from composting of olive-mill wastewaters

International Biodeterioration & Biodegradation, 1996
The aerobic bioremediation of olive-mill wastewaters produces a high quality compost, characterized by a considerable presence of nutrients, mainly organically-bound nitrogen (1.5-3%), a good level of humification (degree of humification=78%; humification index=0.28), and by the absence of phytotoxicity.

Olive Mill Wastewater Treatment

2006
The cultivation of olive trees and the production and use of olive oil has been a well-known and established practice in the Mediterranean region for more than 7000 years. The consumption of olive oil is rapidly increasing worldwide, due to its high dietetic and nutritional value. According to the IOOC (2004), the production of olive oil increased from

Olive-Mill Wastewater Composting: Microbiological Aspects

Waste Management & Research: The Journal for a Sustainable Circular Economy, 1997
Oxygen consumption, microbial growth, lignin and phenol degradation, urease, protease and nitrogenase activity were determined during the composting of an olive- mill wastewaters (OMW)—wheat straw mixture. Oxygen consumption, microbial growth and urease activity were greatly enhanced during the thermophilic phase, reaching their maximum in about three ...

Olive oil mill wastewater valorisation by fungi

Journal of Chemical Technology & Biotechnology, 2006
AbstractThis paper presents a brief survey of studies conducted at the Laboratory of Applied and Environmental Microbiology of the University of Tuscia on the possible biotechnological valorisation of olive mill wastewater (OMW) using fungi. Besides being a serious environmental problem, OMW might be a possible resource owing to the presence of added ...

Electrochemical oxidation of olive oil mill wastewaters

Water Research, 2005
The electrochemical oxidation of olive oil mill wastewaters over a titanium-tantalum-platinum-iridium anode was investigated. Batch experiments were conducted in a flow-through electrolytic cell with internal recycle at voltage of 5, 7 and 9 V, NaCl concentrations of 1%, 2% and 4%, recirculation rates of 0.4 and 0.62 L/s and initial chemical oxygen ...

Electrochemical treatment of olive mill wastewater

Journal of Chemical Technology & Biotechnology, 2007
AbstractBackground Olive mill wastewater (OMW) constitutes a very strong agro‐industrial wastewater posing severe environmental threats in olive oil producing countries. The main objective of this study was to treat olive mill wastewater by electrochemical oxidation.

Ozonation of weathered olive mill wastewaters

Journal of Chemical Technology & Biotechnology, 2006
AbstractThe treatment of fully and partly weathered olive mill wastewaters by means of ozonation was investigated, with emphasis on the effect of treatment conditions (organic loading, treatment time, ozone concentration) on the extent of chemical oxygen demand (COD) and total phenol degradation, colour removal as well as ecotoxicity to the marine ...
