The present paper focuses on a largely unexplored field of landfill-site valorization in combination with the construction and operation of a centralized olive mill wastewater (OMW) treatment facility. The latter consists of a wastewater storage lagoon, a compact anaerobic digester operated all year round and a landfill-based final disposal system. Key elements for process design, such as wastewater pretreatment, application method and rate, and the potential effects on leachate quantity and quality, are discussed based on a comprehensive literature review. Furthermore, a case-study for eight (8) olive mill enterprises generating 8700 m(3) of wastewater per year, was conceptually designed in order to calculate the capital and operational costs of the facility (transportation, storage, treatment, final disposal). The proposed facility was found to be economically self-sufficient, as long as the transportation costs of the OMW were maintained at <= 4.0 (sic)/m(3). Despite that EU Landfill Directive prohibits wastewater disposal to landfills, controlled application, based on appropriately designed pre-treatment system and specific loading rates, may provide improved landfill stabilization and a sustainable (environmentally and economically) solution for effluents generated by numerous small- and medium-size olive mill enterprises dispersed in the Mediterranean region.

Overview of microbes based fabricated biogenic nanoparticles for water and wastewater treatment Ali, Imran; Peng, Changsheng; Khan, Zahid M.; Naz, Iffat; Sultan, Muhammad; Ali, Mohsin; Abbasi, Irfan A.; Islam, Tariqul; Ye, Tong (Elsevier BV, 2019-01-15) Treatment of toxic and emerging pollutants (T&EPs) is increasing the threats to the survival of conventional wastewater treatment (WWTs) technologies. The high installation and operational costs of advanced treatment technologies have shifted the research interest to the development of economical and reliable technology for management of T&EPs. Thus, recently biogenic nanoparticles (BNPs) fabricated using microbes/microorganisms are getting tremendous research interest due to their unique properties (i.e. h...
Bacterial application increased the flow rate of CaCO3-clogged emitters of drip irrigation system Eroğlu, Seçkin; Tunc, Talip; Sahin, Fikrettin (Elsevier BV, 2012-05-01) CaCO3 is one of the most common emitter clogging factors among chemical precipitates in drip irrigation systems. Continuous acid application as a classical approach to prevent CaCO3 clogging can be tricky, expensive and hazardous for soil. In order to develop an environmentally friendly method to address the problem, two bacterial strains, one renowned as a PGPR and the other having extensive CaCO3 dissolving capacity, were used in treatments of artificially clogged drip irrigation emitters. Results showed ...
Cost-effective approach to ethanol production and optimization by response surface methodology Uncu, Oya Nihan; Çekmecelioğlu, Deniz (Elsevier BV, 2011-04-01) Food wastes disposed from residential and industrial kitchens have gained attention as a substrate in microbial fermentations to reduce product costs. In this study, the potential of simultaneously hydrolyzing and subsequently fermenting the mixed carbohydrate components of kitchen wastes were assessed and the effects of solid load, inoculum volume of baker's yeast, and fermentation time on ethanol production were evaluated by response surface methodology (RSM). The enzymatic hydrolysis process was complete...
An NGO role in enhancing integrated coastal management in the Mediterranean and the Black Sea: The MEDCOAST experience Ozhan, E (Elsevier BV, 2000-01-01) In the early 1990s, integrated coastal management (ICM) in the Mediterranean basin found general acceptance as an important issue both at national and international levels, and since then it has been, though slowly, steadily developed. Donor organizations such as the European Union and the World Bank, and the UNEP's Mediterranean Action Plan played catalyst roles in this development by initiating and supporting pilot projects. In 1992, the European Union launched the Mediterranean programs in which the envi...
Degradation of decabromodiphenyl ether (BDE-209) in microcosms mimicking sediment environment subjected to comparative bioremediation strategies Demirtepe, Hale; İmamoğlu, İpek (Elsevier BV, 2019-03-01) The aim of this study was to examine bioremediation strategies for BDE-209 contaminated sediments. Sediment microcosms were established to observe anaerobic debromination of BDE-209 under conditions representing three bioremediadon strategies: biostimulation, bioaugmentation and natural attenuation. To simulate biostimulation, a defined mineral medium containing both a carbon source (sodium formate) and electron donor (ethanol) was added into sediments. Bioaugmentation was established by enrichment of the s...
