Treatment technologies for olive mill wastewater with impacts on plants.

Environmental Research, 2022
Olive mill wastewater (OMW), produced during olive oil production, contains high levels of salt contents, organic matter, suspended particles, and toxic chemicals (particularly phenols), which all result in increased biological and chemical oxygen demand.

State of knowledge on chemical, biological and nutritional properties of olive mill wastewater.

Food Chemistry, 2022
The Mediterranean olive oil industries are producing annually a massive quantity of olive mill wastewater (OMWW). Unfortunately, the OMWW is released arbitrarily in the nature without any pretreatment.

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

CuCr2O4@CaFe-LDO photocatalyst for remarkable removal of COD from high-strength olive mill wastewater.

Journal of Colloid and Interface Science, 2021
Wastewater from the olive mill constitutes a serious environmental concern, as it is characterized by a high inorganic and organic load. Here, a hybrid photocatalyst based on calcined Ca-Fe-LDH was successfully synthesized for the degradation of phenolic

Mitigation of Olive Mill Wastewater Toxicity

Journal of Agricultural and Food Chemistry, 2006
The toxicity of olive mill wastewaters (OMW) is commonly attributed to monomeric phenols. OMW were treated in an aerated, stirred reactor containing agricultural soil, where the oxidative polymerization of phenols took place. In 24 h, OMW monomeric phenols decreased by >90%.

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.

Olive mill wastewater treatment and valorization by extraction/concentration of hydroxytyrosol and other natural phenols

, 2021
Olive mill wastewater (OMW) is a by-product generated from olive oil extraction systems. It contains high concentrations of organic compounds mainly phenols which cause environmental problems for the ecosystem, such as soil contamination and water ...

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
