Abstract:In this work, olive mill wastewater (OMW) such as dyes is very toxic even present as traces in industrial wastewater effluents. It may constitute a potential pollution source of ground waters and hence it has to be eliminated. Various low cost adsorbents have been studied for their applicability in treatment of different types of effluents. In this study, the potential of activated carbon derived from Olive Stones was studied for the removal of OMW. The biosorption of OMW from aqueous solutions by Oliv… Show more

“…Pappas et al optimized the use of PEF for the recovery of high-value compounds from fresh olive leaves, achieving a significant increase in polyphenol extractability [161]. Yassine et al also found success in treating olive mill wastewater using electrocoagulation, a process that involves the application of an electric current [162]. In the context of olive oil extraction, Tamborrino et al and Romanielloa et al both demonstrated the potential of PEF technology to improve extractability and enhance oil quality.…”

Olive mill waste (OMW) is a by-product of the olive oil production process that has attracted increasing attention due to its rich composition of bioactive compounds. This chapter explores the extensive and diverse antioxidant and bioactive potential of OMW. OMW is a complex mixture comprising organic compounds, including phenolic compounds, flavonoids, polysaccharides, and various other valuable molecules. These compounds have demonstrated a wide range of applications, including their use as fertilizers, antioxidants, antifungal and antibacterial agents, cytoprotective agents, and stabilizing agents in food preservation. The chapter delves into the types of phenolic compounds found in OMW, providing detailed insights into their structures and functions. Additionally, it discusses the factors affecting the composition of OMW, such as the extraction process and processing conditions. Additionally, the chapter explores the growing interest in the health benefits associated with the consumption of bioactive compounds derived from OMW. These compounds have been linked to potential therapeutic properties, including antioxidant, anti-inflammatory, and anticancer effects. The exploration of OMW’s bioactive potential opens avenues for research and innovation, offering sustainable solutions for both waste management and the development of health-promoting products.
“…The authors of [26] studied the sorption potential of activated carbon obtained from olive pits for the purification of olive mill wastewater. The biosorption by untreated olive pits and those treated with KOH and H 3 PO 4 was studied.…”
The effective purification of large-capacity wastewater from heavy non-ferrous metals and organic pollutants using inexpensive sorption technology remains a crucial task. Analyzing the current objectives of sustainable development, biochar obtained from chicken manure has prospects as a source for sorption purification of industrial wastewater. To determine the characteristics of organic material and the composition of the initial and equilibrium phases, the following analysis methods were used: volumetric, complexometric, pH-metric, X-ray fluorescence, chromatographic, spectrophotometric, luminescence-photometric and X-ray diffraction. The thermal nitrogen desorption method was used for determining the specific surface area and pore sizes with the Quantachrome Nova 1000e automatic analyzer. The sorption properties of the reprocessing product of the fresh poultry manure were investigated in relation to organic and inorganic compounds: phenols, benzene, ketones, cations of lead, mercury, manganese and iron. Based on the results obtained, technical conditions were developed for the use of the reprocessed organic waste-based product as a sorption material for household, industrial and technological wastewater purification from organic and inorganic components.
