“…Zeytinyağı atıksularında yüksek konsantrasyonlarda bulunan fenolik bileşikler, fitotoksisite ve antimikrobiyal özelliklere sahip olan ve biyolojik olarak ayrışması zor olan kalıcı bileşiklerdir [22]. Bununla birlikte, düşük pH ve polifenollerin kompleks oluşturma yetenekleri çevredeki ağır metallerin çözünürlüğünü arttırmaktadır [27].…”

ÖzZeytinyağı üretim atıksuları; mevsimsel üretim, tesislerin geniş arazilere yayılması, yüksek organik yük gibi çeşitli faktörlerden dolayı zeytinyağı üretimi yapan Akdeniz Ülkelerinde ciddi bir çevresel problemdir. Bu atıksuların miktarı ve kirlilik yükü kullanılan üretim prosesine ve işletim koşullarına bağlı olarak değişmektedir. Organik madde, askıda katı madde, yağ ve gres içerikleri oldukça Characteristics of Olive Oil Wastewater, Its Environmental Effects and Treatment Technologies AbstractOlive oil manufacturing wastewater is a serious environmental problem in the Mediterranean regions due to several factors such as seasonal production, distribution over large areas of mills, high organic load. Amount and pollutant load of this wastewater changes depending production process used and operational conditions. Organic matter, suspended solid matter, oil and grease contents of this wastewater are quite high. Treatment of olive oil wastewaters becomes difficult due to high organic matter, seasonal

SELECTION of cost-effective treatment modules for high saline wastewater produced from the olive mill is a challenging task. The aim of this study is to select the most effective technology applied to treat Olive mill wastewater. Several trials using various techniques were carried out to treat wastewater produced from pickling olives and olive oil manufacturing; for instance, anaerobic-aerobic, coagulation/flocculation, and electrocoagulation. The characteristics of olive manufacturing raw wastewater in terms of total dissolved solids (TDS), chemical oxygen demand (COD) and oil and grease were 10032, 9174, and 914.8 mg/l respectively. The results showed that electro-coagulation technique with aluminum electrodes and operating parameters of 30 voltage and 1.5 hours achieved COD removal rate 84%. However, the residual concentration (900 mgO 2 /l) still needs further treatment. Aerobic treatment using activated sludge was applied after electrocoagulation. The results showed that the use aerobic treatment after electrocoagulation is more efficient than the use of anaerobic. Analysis of the treated water showed that the maximum COD removal efficiencies were 98% at optimum conditions. The effluent quality meets the discharge regulatory standard. Consequently, the electrocoagulation followed by aerobic process can be considered as a reliable, safe and costeffective method for the treatment of olive millwastewater.

“…Besides these methods; advanced treatment processes such as ozonation [7]- [8]- [9], photocatalysis [10], electrocoagulation [5]- [11], fenton oxidation [12], ozone and fenton oxidation [13] and wet air oxidation [14] have been tested for olive mill wastewater treatment. However, these processes have a disadvantage of either high operating costs or high sludge quantities which requires additional treatment thereby additional investment and operating cost.…”

Abstract-The aim of this study is the investigation of electrohydrolysis treatment process for olive mill wastewater in terms of pollutants removal and hydrogen production. For this purpose, Different voltages including 4, 6 and 8 V DC were tested for 3 hours. 8 V DC for 3 hours was found to be as the most effective condition. At this optimum voltage, different time periods were also investigated. At 8 V, significant pollutant removal efficiencies were obtained. 68% turbidity, 70% TSS, 52% COD and 19% sCOD removal efficiencies were achieved. Volume of produced gas was 1500±10 ml and hydrogen percent was determined as 85%. Hydrogen production along with pollutant removal is one of the advantages of electrohydrolysis. Therefore, electrohydrolysis can be proposed as a feasible alternative treatment step for wastewaters which is characterized by high organic matter and also suspended matter.
