“…During the seasonal harvesting of olives, a large amount of a liquid waste called olive oil mill wastewater (OMW) is produced and becomes a major environmental problem (Kavvadias et al 2010;Justino et al 2012). The OMW constituents depend on several factors such as the soil nature, cultivation system, olive varieties and production process (Roig et al 2006;McNamara et al 2008).…”

This study aims to attempt a treatment strategy based on fungi immobilized on silica-alginate (biocomposites) for removal of phenolic compounds in olive oil mill wastewater (OMW), OMW supplemented (OMWS) with phenolic compounds and water supplemented (WS) with phenolic compounds, thus decreasing its potential impact in the receiving waters. Active (alive) or inactive (death by sterilization) Pleurotus sajor caju was encapsulated in alginate beads. Five beads containing active and inactive fungus were placed in a mold and filled with silica hydrogel (biocomposites). The biocomposites were added to batch reactors containing the OMW, OMWS and WS. The treatment of OMW, OMWS and WS by active and inactive biocomposites was performed throughout 28 days at 25°C. The efficiency of treatment was evaluated by measuring the removal of targeted organic compounds, chemical oxygen demand (COD) and relative absorbance ratio along the time. Active P. sajor caju biocomposites were able to remove 64.6-88.4 % of phenolic compounds from OMW and OMWS and 91.8-97.5 % in water. Furthermore, in the case of OMW there was also a removal of 30.0-38.1 % of fatty acids, 68.7 % of the sterol and 35 % of COD. The silica-alginate-fungi biocomposites showed a high removal of phenolic compounds from OMW and water. Furthermore, in the application of biocomposites to the treatment of OMW it was observed also a decrease on the concentration of fatty acids and sterols as well as a reduction on the COD.

Detection of olive oil mill waste (OOMW) disposal areas using high resolution GeoEye’s OrbView-3 and Google Earth images

Abstract:The olive oil industry is considered to be as one of the driving sectors of the agricultural economy of the Mediterranean basin. The extraction of olive oil generates huge quantities of wastes that may have a great impact on land and water environments due to high concentrations in phenolic compounds that could cause ophytotoxicity. This paper aims to examine the potential use of freely distributed satellite images for the detection of olive oil mil waste (OOMW) areas in the island of Crete through the use of two cases studies. In the first case study an archive GeoEye OrbView-3 image was used to detect OOMW areas using the Spectral Angle Mapper detection algorithm and other geometric and topographic parameters. In the second case study, Google Earth images were examined through different classification algorithms at different scales. The overall results demonstrate that remote sensing techniques can be used as an alternative to field observations so as to detect and monitor OOMW areas Furthermore, freely distributed RGB images from digital globes (such as Google Earth) can be sufficiently and effectively used for this purpose.

“…Zeytin atığının toprakla karıştırılarak yapılan uygulamalarında da, yağış yoğun-lukları yüzey akış ve toprak kaybını önemli düzeylerde arttırırken, uygulama oranları ise drenajı ve parselden ölçülen EC'leri önemli düzeylerde arttırmıştır. Yapılan bazı araştırmalarda da benzer istatistik sonuçlar bulunmuştur (Kavvadias et al, 2010;Garcia-Lozano et al, 2011;Liu et al, 2012;Won et al, 2012). Ayrıca bu ça-lışmada, zeytin atığı ile pH (toprak ve drenaj) arasın-da önemli bir ilişkisi saptanamamıştır.…”

Yapılan bir diğer çalışmada, araziye uygulanan zeytinyağı fabrikası atıklarının toprakta EC'yi arttırırken, pH'ı ise marjinal etkilediği bulunmuştur (Kavvadias et al, 2010). Candemir and Gülser, (2011) killi ve tınlı kumlu arazilerde hazırladıkları parsellere uyguladıkları gübre, fındıkkabuğu, çay ve tütün atıklarının toprak fiziksel özelliklerini iyileştirmeleri yanında pH ve EC'yi arttır-dıklarını bulmuşlardır.…”

ÖZETnsan yaşamının en önemli doğal kaynaklarından biri olan toprak, erozyonla kaybolmaktadır. Toprak kayıplarını azaltmak için çeşitli teknikler geliştirilmektedir. Bu tekniklerden biri de topraklara çeşitli organik materyalleri uygulamaktır. Bu araştırmada, 30x45x15 cm boyutlu ve altında drenaj borusu olan erozyon parseline, 8 mm'den elenmiş tınlı bünyeli toprak örneği yerleştirilmiş ve zeytin atıığı dört farklı doz (0, 10, 20 ve 40 t/ha) ve iki farklı yöntemle (serme ve karıştırma) uygulanmıştır. Parsellere 30, 60 ve 90 mm/saat yoğunluklarda yapay yağışlar uygulanmıştır. Deneme konusu toprak örneklerinde ve drene olan sularda pH ve elektriksel iletkenlik (EC) değerleri ölçülmüştür. Yağış uygulamalarından sonra elde edilen yüzey akış, toprak kaybı ve drenaj miktarları hesaplanmıştır. Araştırma sonuçlarına göre; zeytin atığı yüzey akışı ve toprak kayıplarını önemli düzeylerde azaltırken, drenajı önemli düzeylerde arttırmıştır. Ayrıca zeytin atığı, pH ve EC üzerinde de önemli düzeylerde etkili olmuştur. Sererek uygulanan organik materyal, denemede karıştırma yapılarak uygulanan organik materyalden daha etkili bulunmuştur.ABSTRACT oil, one of the most important natural resources for human life is lost by erosion. To reduce soil loss, various techniques have been developed. One of these techniques is to apply a variety of organic materials in soils. In this study, a loamy soil sample passed throught 8 mm sieve was placed into erosion pans which have a drain pipe and sized as 30x45x15 cm. Olive mill waste was applied to erosion pans at 4 different doses (0, 10, 20 and 40 t/ha) by 2 different methods (unmixed, and mixed). Artificial rainfall with different intensities (30, 60 and 90 mm/h) were applied on these pans. Soil reaction (pH) and electrical conductivity (EC) values of experimental soils and drained waters were measured. The results indicated that, runoff and soil loss from the erosion pans were decreased and drainage increased significantly by application of olive mill waste. Olive mill waste also effected on pH and EC significantly. It was found that surface applied organic material was more effective than mixed applied organic material on erosion. GİRİŞİnsanlığın geleceğini tehdit eden erozyon, sadece basit anlamda toprakların aşınıp taşınması değildir, aynı zamanda çok karmaşık olan mekanik bir işlevdir. Su erozyonuna karşı, en önemli doğal kaynaklardan olan toprakların korunması için, çeşitli teknikler uygulanmaktadır. Bu tekniklerden biri de organik materyallerin (bitki atıkları, kâğıt fabrikası atıkları, tütün atıkları vb.
