Aerobic degradation of olive mill wastewaters

Applied Microbiology and Biotechnology, 1997
The degradation of olive mill wastewater by aerobic microorganisms has been investigated in a batch reactor, by conducting experiments where the initial concentration of organic matter, quantified by the chemical oxygen demand, and the initial biomass were varied.

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

Hydrothermal carbonization of olive mill wastewater

Bioresource Technology, 2013
Hydrothermal carbonization (HTC) is an emerging technology to treat wet biomasses aimed at producing a biochar material. Herein, olive mill wastewater (OMW) was subjected to HTC. Mass balance considerations provide evidence that the yield of biochar is low (~30%, w/w), which is associated with a low fraction of carbohydrates in OMW.

Bioremediation of Olive-Mill Wastewaters By Composting

Waste Management & Research: The Journal for a Sustainable Circular Economy, 1995
Olive-mill wastewaters (O.M.W.) containing about 7% solids were composted with wheat straw in a forced aeration static pile. Two percent urea was added to ensure a C/N ratio of about 35. To avoid overdosing with water, a fraction of the O.M.W. equal to the weight of the straw was added initially.

Antimicrobial activity of olive mill wastewaters (alpechin) and biotransformed olive oil mill wastewater

International Biodeterioration & Biodegradation, 1996
Abstract Olive oil extraction produces a great volume of residue. These olive mill wastes are known as alpechin. This wastewater is a powerful pollutant, resistant to degradation and presents a severe environmental problem related to its high organic content made up largely of simple phenolic compounds, that have been described as being both ...

Electrocoagulation of olive mill wastewaters

Separation and Purification Technology, 2006
Abstract An attempt has been made to remove chemical oxygen demand (COD) from olive mill wastewaters (OMW) as well as oil-grease and turbidity in the presence of H 2 O 2 and polialuminum chloride (PAC), as a coagulant-aid by an electrochemical method using either iron or aluminum as sacrificial electrodes.

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

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 ...

Characteristics and biodegradability of olive mill wastewaters

Environmental Technology, 2015
Olive mill wastewaters (OMWs) are mostly characterized by their high-organic content and complex organic compounds in addition to the phenolic compounds. European olive oil manufacturers have to cope up with the same wastewater treatment problem and the applied conventional treatment technologies for OMW were not proved to be very successful in each ...
