“…Les tentatives de traitements biologiques des margines sont restées limitées à cause de la présence de composés phénoliques toxiques qui sont difficilement biodégra-dables et inhibiteurs de l'activité biologique [4,5,6] . La biométhanisation utilisée en particulier pour la dégradation des rejets très chargés en matière organique est inhibée par la présence de ces polyphénols [7,8,9] . Cependant cette toxicité a été réduite par des levures et des champignons spéci-fiques [10,11,12,13] ou par pré-traitement physique sous l'effet d'un champ ultrasonore [14] .…”

Olive mill wastewaters (OMW) constitute a major environmental problem particularly in Mediterranean countries. Most of the biological treatment processes, physico-chemical treatment or valorisation methods of OMW showed some limitations. This could be partly due to the heavy load in organic compounds and to the high load in polyphenols of these sewages. The phenolic compounds are toxic for fauna and flora, inhibitory of the biological activity and their biodegradation is very difficult. The analysis by GC/MS of different samples of OMW, permitted to identify a big variety of phenolic compounds. Several of these have been identified for the first time. In this work we analysed a variety of phenolic compounds depending on the different processes of olive oil extraction and the influence of storage time. Les margines constituent jusqu'à présent un problème environnemental majeur pour les pays producteurs d’huile d’olive. La plupart des processus de traitement biologique, physico-chimique ou de valorisation de margine ont montré leur limite à cause de la complexité de cet effluent très chargé en matière organique et minérale et particulièrement en composés phénoliques. Ces derniers sont toxiques pour la faune et la flore, difficilement biodégradable et inhibiteur de l’activité biologique. L’analyse par GC/MS des extraits de différents échantillons de margines, nous a permis d’identifier une grande variété de composés phénoliques dont plusieurs ont été identifiés pour la premières fois. Dans le cadre de ce travail on s’est intéressé à l’étude de la variation et l’évolution des composés phénoliques en fonction de l’origine des margines.

“…Single-stage digestion has been used at laboratory scale recently for feedstocks including OFMSW (Gallert et al, 2003, Bolzonella et al, 2003, wastewater and solid food wastes from food processing (Beccari et al, 1999, Carucci et al, 2005, and slaughterhouse wastes (Salminen andRintala, 2002, Siegrist et al, 2005). This last type of waste is high in proteins and lipids, and is relevant as the food waste feedstock used in this study also has a high lipid content.…”

Source-separated food wastes collected from a university campus catering facility were processed in bench-scale anaerobic digesters. The feedstock contained a varied mix of fruits, vegetables, meats and fried foods. Two modes of digestion were compared. The first was hydraulic flush (HF) mode, in which liquids were flushed through the reactor on a retention time of 25 days while solids were maintained on an extended retention time of over 150 days. The converse was a solids wastage (SW) mode, in which liquid retention time was over 150 days, and solids were wasted to maintain a retention time of 25 days. SW reactors exhibited methanogenic failure after approximately 45 days. HF reactors, in contrast, maintained stable digestion for a period of 100 days, and were robust enough to recover from a thermal shock applied over a three-day period in which the temperature was increased from 35 0 C to 50 0 C between days 105-108 of the experiment. Stable operation was regained by day 139 and continued until the end of the run on day 150.

“…Ayrıca fenolik bileşikler ve mineral tuzların varlığından kaynaklanan yüksek toksisite ve biyoayrışma inhibisyonundan dolayı pek çok problem yaşanmaktadır [10]. Bu durum anaerobik arıtmadan önce mümkün olduğu kadar daha seçici bir şekilde lipitleri ve fenolik bileşikleri gidermek için fiziksel-kimyasal ön arıtma seçeneğinin yürütülmesi gerektiğine işaret etmektedir [25]. …”

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
