“…On the other hand, the advanced oxidation methods are very effective, but they also have high costs. Besides, the treatment of OMW by a combination of chemical or physical processes and a biological process has not been completely successful, and a longer lag phase has been found to be necessary for biological treatment [62,63]. In addition, reuse of the OMW by spreading onto agricultural soil as an organic fertilizer has been considered [60].…”

Food wastes are today considered as a cheap source of valuable components since the existent technologies allow the recovery of target compounds and their recycling inside the food chain as functional additives in different products. Olive mill wastewater (OMW) is generated from olive oil extraction systems. It has high addedvalue compounds namely phenolics, recalcitrants, pectin, and some important enzymes. It causes a certain amount of toxicity/phytotoxicity because of its phenolic compounds. OMW also has significant impacts when discharged directly into surface waters. Therefore, the treatment of olive mill wastewater is very much needed. Several types of techniques have been investigated for OMW treatment along with recovery and removal of its phenolic compounds. Among these techniques, physical ones are utilized for extraction purposes, while chemical and biological methods are applied in order to diminish organic load. In this review, current status and recent developments in the recovery and removal of phenolic compounds from OMW have been critically examined.

“…This waste is usually treated by a number of physical, chemical and biological techniques in water treatment units of oil refinery, before being disposed in environment or reused as agricultural water. One of the treatment techniques used for oil separation from wastewater is membrane filtration (Karakuleski et al 1995;Marchese et al 2000;Tomaszewska et al 2005;Akdemir & Ozer 2008). applied for treating oily wastewaters (Koltuniewicz et al 1995;Kim 1997;Marchese et al 2000;Madaeni et al 2001;Mohammadi & Esmaeelifar 2005).…”

Investigations were carried out for purification of oily wastewater by a combined of ultrafiltration/reverse osmosis (UF/RO) processes. Laboratory-scale UF using polysulfone (PS) and polyacrylonitrile (PAN) membranes were employed with typical oily wastewater collected from API unit of Tehran refinery. The PAN membrane showed higher rejection, more permeation flux and less fouling resistance than the PS membrane. Both membranes produced permeate with oil and grease contents generally less than 5 ppm. Rejection of chemical oxygen demand (COD) and biological oxygen demand (BOD5) were found to be 65% for UF treatment. In this work, Hermia's models were used to investigate the fouling mechanism involved in UF of the oily wastewater. The results showed that the best fit to experimental data corresponds to the cake layer formation model followed by the intermediate blocking model for both the UF membranes. For further treatment of the UF permeates, RO was applied using a thin film composite polyamide membrane. The rejection of COD, BOD5 and total dissolved solid (TDS) after UF/RO treatment increased up to 98%, 98% and 95%, respectively. The results showed that the final permeate has very high quality and even better than that is currently introduced to the cooling towers in Tehran refinery.

“…Transmembrane pressure, COD removal and the permeate flux were used as variables. Optimal fluxes (34.4 L/m 2 /h) and removal rates (89.5% of COD) were at opposite ends of flowrate and pressure ranges (Akdemir and Ozer, 2008).…”
