يتمحور جوهر هذا البحث في الاختيار الأمثل لمواقع تجفيف نواتج المعاصر (الجفت) بحيث تحقق الشروط البيئية الصارمة، و التي بدورها تتعلق بمجموعة كبيرة من العوامل منها الطبوغرافية، و هي: الارتفاعات و الأنهار و المسيلات و البحيرات و الفوالق، و منها المتعلقة بالعناصر الجغرافية من صنع الإنسان، و هي: المدن و القرى و الطرق و السدود و الآبار و المعاصر. لإنجاز الدراسة و الحصول على النتائج الموثوقة، تم الاعتماد على نظام المعلومات الجغرافي GIS، الذي يتطلب تعريف كل العوامل المذكور أعلاه، على شكل بيئة رسومية و وصفية. إن اختيار المواقع المحتملة يكون من خلال التحقق من الشروط المطلوبة باستخدام نظم المعلومات الجغرافية GIS، و هذا يتطلب وجود معطيات خاصة بكل شرط، و التحقق من الشروط الأخرى من خلال جولات و قياسات حقلية في حال عدم وجود البيانات اللازمة، و من الضروري الاستعانة بالصور الفضائية المتاحة بشكل كبير من خلال GOOGLE-EARTH للتحقق الأولي من المواقع المختارة. يتم استخدام التقانة المناسبة بحسب حالة ماء الجفت، و بحسب الإمكانات الاقتصادية لتطبيق هذه التقانة، و الهدف الأساس من هذه المعالجات هو تخفيض حمولتها من المواد العضوية، حيث ستستخدم المياه المتبقية في ري الأراضي الزراعية، أو يمكن استخدام طرائق التدوير للمخلفات الصلبة الناتجة عن عصر الزيتون من أجل إنتاج السماد العضوي و تغذية المواشي.
The aim of this research is to optimize the selection of the sites of Evaporation Tanks/Ponds, of Olive Mill Waste Water (OMWW). We have to achieve strict environmental conditions, which in turn relate to a wide range of factors including topography, namely: elevations, rivers, silos, lakes and faults, in addition of those related to man-made geographical elements: cities, villages, roads, dams, wells and contemporary. To complete the study and obtain reliable results, we adopt GIS, which requires defining all of the above factors in the form of a graphical and descriptive environment. The choice of potential sites is through verification of the required conditions using GIS. This requires the availability of data specific to each condition, verification of other conditions through field visits and measurements in the absence of necessary data, and it is necessary to use the available space images significantly through GOOGLE EARTH for initial verification of selected sites. Appropriate technology is used according to the state of the OMWW, and according to the economic potential of the application of this technology. The main objective of these treatments is to reduce their load of organic matter. The remaining water will be used to irrigate the agricultural land. Production of manure and feed of cattle.

The research aims to study the economic efficiency of olive mill wastewater
(OMWW) use in fertilizing olive trees, Which included research sample / 294 / farmer in
Lattakia Governorate, depending on the descriptive analytical method,And found the
results to be to fertilize the olive trees with (OMWW) rents high productivity, Where it
posted a net profit of (33,668) SP / acre / year, while gross margin stood at (61 235) SP ,
The coefficient of profitability compared to the cost of production (about 41.32%)%, while
the profitability coefficient was compared to the capital invested approximately 42.98%.
Determining the best location is a complex process that faces decision makers. In the City of Tartous, Syria, this problem springs while selecting the best location for wastewater treatment plant (WWTP) because of the large number of criteria and co
nstrains and the uncertainty in expert's judgments. To solve this problem, we designed a frame work containing multi-criteria decision making (MCDM) technique that is fuzzy analytic hierarchy process (FAHP) to handle the uncertainty situations and geographical information system (GIS) to determine the best location.
In this paper, the FAHP idea was developed to calculate weights of the criterias, the GIS was used to overlay and generate criteria and suitability maps. The study ends with a map of the best sites for constructing wastewater treatment plants by extended aeration method in Tartous region in Syria.
3,4-dihydroxybenzoic acid is one of phenolic compounds that exists in olive mill waste water (OMWW) and different industrial wastewater.Commercially activated charcoal was studied as absorbent of polyphenols. The value of specific surface area was 73
6.7189 m2/g. Equilibriums of 3,4-dihyroxybenzoic acid from aqueous solutions on four different particle sizes of the adsorbent with diameters ranged A(1000-2000), B(500-1000), C(250-500), D(125-250)m was examined at different initial concentrations ofabsorbate. The experimental data were analyzed using the Langmuir and Freundlich isotherm models. Both the isotherm models fit the adsorption data. Monolayer absorption capacities Q0 calculated from Langmuir equation were (0.36, 0.23, 0.34, 0.35mmol/g) for the different granular activated carbon sizes (A,B,C,D) respectively. The values of constant Kf calculated from Freundlich equation were (0.75, 0.61, 0.76, 0.79mmol/g) for the four sizes of granular activated carbon (A,B,C,D) respectively.
The results show that the charcoal activated carbon can be used as absorbent for polyphenol compounds.
Solid waste management is a complex problem facing decision makers in Tartous,
especially in the process of selecting appropriate of solid waste land fill sites, because of
the nature of the province that rich in natural resources and high populati
on density. There
is a large number of large landfills that aren’t in convenient locations, and affect to
neighboring regions environment, adversely affect to the social life in the surrounding
communities.
In this research we identified the criteria that will be on the basis of evaluation of the
locations of these landfills to achieve environmental, social and economic conditions.
GIS was used to produce maps for each classification criterion separately to evaluate
the landfills according to each criterion, in order to extract information from weighted map
to get the appropriate locations.
The study concluded that landfills sites unrealized for the majority of the standards,
and to get a map showing the optimum locations of 18 sites with combined areas doesn’t
exceed 0,012% of the total study area.
The study was conducted to determine the efficiency of the aerobic treatment of primary sludge resulting from sewage sedimentation and to determine the optimum residence time by measuring the indicators of total solids, chemical oxygen demand, organic content and dewatering ability of the sludge.
