Degradation of olive mill wastewater by different methods and antioxidant activity of olive mill wastewater extraction [PDF]

SN Applied Sciences, 2019
Olive wastewater (OMW) is an important environmental problem due to the high phenol level and contains organic substances such as sugars, organic acids, polyalcohols, pectins, colloids, tannins, and lipids. Removing OMW is difficult because of the high concentrations of chemical oxygen demand (COD), biochemical oxygen demand, and phenolic compounds. In

Polymeric biophenols in olive mill wastewaters [PDF]

Planta Medica, 2011
Olive mill wastewater (OMW), the effluents generated in the olive oil extraction industry operating in three-phases mode, are phytotoxic mainly due to its high phenolic content [1]. On the other hand, attending to the potential healthbenefits of some of their phenolic compounds, OMW are now regarded as a potent source of biophenols for food and ...

Techno-economic analysis of olive wastewater treatment with a closed water approach by integrated membrane processes and advanced oxidation processes

Water Reuse, 2021
In this paper, a reliable treatment process for olive mill wastewaters (OMWW) is proposed. In order to develop a more sustainable process with polyphenols recovery and water reuse, two treatment schemes have been simulated by using a process simulator ...
