Olive-mill wastewater (OMW) is a by-product effluent of olive oil extraction process that is produced in large amount in the Mediterranean region. OMW is believed to induce phytotoxic effect on organisms including seed germination and plant growth.Get Price
PYROLYSIS AND OXIDATION KINETICS OF OLIVE MILL WASTE by Li Buessing University of New Hampshire, May 2012 This study investigates the utilization of the olive mill waste stream before and after the removal of entrained phenolic compounds. The kinetics of pyrolysis and oxidation were analyzed via thermogravimetric analysis.Get Price
Kinetics of the anaerobic purification of aerobically prebiotreated olive mill wastewater A kinetic study has been carried out on the process of anaerobic purification of an olive mill wastewater pre-treated aerobically to eliminate the greater part of the phenolic compounds responsible for inhibition.Get Price
The aerobic biodegradation of green table olive wastewaters achieves a significative reduction of the COD between 50 and 70%, and an important removal of the total polyphenolic compounds around 97%, while the biomass follows the typical growth cycle phases for batch cultivations.
Olive mill wastewater (OMWW) The OMWW used in this study was obtained from a three‐phase olive oil mill located in central Greece, at the province of Fthiotida. Approximately, 200 L of OMWW were transferred to the Organic Chemical Technology Laboratory (NTUA) and stored at –30 °C for further use.
Olive-oil production has a vital impact on the socioeconomic development in most Mediterranean countries, where 97.5 % of the world oil is produced. However, the olive-oil extraction process generates considerable quantities of an agro-industrial effluent, olive mill wastewater (OMW), which has negative impact on the environment and biological ...Get Price
Wastewater from olive oil mills has been treated by means of the Fe(II)/H2O2 system (Fenton's reagent). Typical operating variables such as reagent concentration (CH2O2 = 1.0−0.2 M; CFe(II) = 0.01−0.1 M) and temperature (T = 293−323 K) exerted a positive influence on the chemical oxygen demand and total carbon removal. The optimum working pH was found to be in the range 2.5−3.0.

The experiments on the olive oil mill wastewater treatment for removing the lipids by anaerobic and aerobic biodegradation with mixed Bacillus spp. culture indicated that the rate of the aerobic process is up to two times higher than that of the anaerobic one.Get Price
AbstractThe commercially available macroporous resin Amberlite FPX66 was evaluated for its capacity to adsorb the polyphenols contained in olive mill wastewater (OMWW). The adsorption was performed in the mode of fixed packed-bed contactor. The effects of OMWW flow rate, temperature, dilution and pH on the resin adsorption capacity were investigated.[PDF]Get Price
The annual production of black and highly toxic olive mill wastewater in the Mediterranean olive-growing countries is estimated at about 10–30 million m 3. The disposal of such effluents without any treatment is known to cause serious environmental problems .Get Price
Olive mill wastewater (OMW) is the byproduct of the extraction process of olive oil from the olive fruits. Therefore, it is seasonally produced in olive-trees growing countries. The vast majority of olive trees are grown in the Mediterranean countries such as Spain, Greece, Italy, and Turkey in addition to some countries in the Middle East and North Africa.
