تهدف هذه الدراسة إلى دراسة فعالية كل من (كلوريد الحديد, الرماد, تفل القهوة) في إزالة الفوسفور من مياه صرف مخابر مرفأ اللاذقية التي يتم تجميعها في حفرة تفتيش منفصلة, و تم إجراء تجارب مخبرية على مياه تحوي تراكيز عالية من الفوسفور سواء أكانت مياه صرف حقيقية أو محاليل عيارية من أوكسيد الفوسفور المخبري. حيث تم تجريب كلوريد الحديد عند جرعات (FeCl3/P=(0-5 كمعدل وزني ليعط نسب فعالية %(-8070) بما يتوافق مع قيمة الـ pH و تم تحديد زمن إعادة تحرر الفوسفور بعد (10 - 12) ساعة من بدء الترسيب, كما تم تجريب الرماد كعامل ممتز بجرعات (Ash/P=(2-4.5 كمعدل وزني لتعط نسب فعالية وصلت إلى 98% و لوحظ إعادة تحرر الفوسفور بعد 11 ساعة مع تحديد قيم الـpH الموافقة لذلك, أما تفل القهوة فعند إضافته بجرعات (Coffee dreg/P =(3-10 كمعدل وزني حقق نسبة إزالة تتراوح % (40 - 99) و عاد للتحرر بعد 24 ساعة و بنتيجة هذه التجارب تم اقتراح الحل الأمثل من الناحية الاقتصادية بالنسبة لحالة الدراسة.
This research aims to study the effectiveness of each(ferric chloride , ash and coffee dregs) to remove phosphorus from Lattakia Port Laboratories' waste water which is assembled in a separate sewage pit by doing laboratory experiments on water containing high concentrations of phosphorus, whether real wastewater or standard solutions of phosphorus oxide. Where it has been experimenting with ferric chloride at doses as weight average(FeCl3/P = (0-5)) to give effectiveness ratios(70- 80)% with determining the value of the pH-compliant and it was noted re-releasing of phosphorus time after(10-12) hours of the start of precipitation, beside that it has been experimenting with ash as adsorpted agent at doses as weight average(Ash/P = (2-4.5)) to give effectiveness ratio which it had reached to 98% where it was noted re-releasing of phosphorus after 11 hours with determining the pH values of approval for that, As coffee dregs when added in doses)Coffee dreg/P = 3-10) as weight average, it fulfilled proportion removal(40 - 99) % and phosphorus re-released after 24 hours. The outcome of these experiments was to propose the most appropriate economic solution in the case of study.

Research summary
تهدف هذه الدراسة إلى تقييم فعالية ثلاث مواد مختلفة (كلوريد الحديد، الرماد، وتفل القهوة) في إزالة الفوسفور من مياه صرف مخابر مرفأ اللاذقية. تم إجراء تجارب مخبرية على مياه تحتوي على تراكيز عالية من الفوسفور، سواء كانت مياه صرف حقيقية أو محاليل معيارية من أوكسيد الفوسفور. أظهرت النتائج أن كلوريد الحديد بجرعات معينة يمكن أن يحقق نسبة إزالة تصل إلى 80%، بينما الرماد يمكن أن يحقق نسبة إزالة تصل إلى 98%، وتفل القهوة يمكن أن يحقق نسبة إزالة تصل إلى 99%. تم تحديد زمن إعادة تحرر الفوسفور لكل مادة، حيث أعاد الفوسفور التحرر بعد 10-12 ساعة من بدء الترسيب لكلوريد الحديد، وبعد 11 ساعة للرماد، وبعد 24 ساعة لتفل القهوة. بناءً على هذه النتائج، تم اقتراح الحل الأمثل من الناحية الاقتصادية لحالة الدراسة.
Critical review
تعتبر هذه الدراسة خطوة هامة نحو تحسين جودة مياه الصرف في مخابر مرفأ اللاذقية. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم تناول تأثير العوامل البيئية الأخرى مثل درجة الحرارة والرطوبة على فعالية المواد المستخدمة في إزالة الفوسفور. ثانياً، الدراسة تركز بشكل كبير على الفوسفور دون النظر إلى الملوثات الأخرى التي قد تكون موجودة في مياه الصرف. ثالثاً، يمكن أن تكون هناك حاجة لتجارب ميدانية إضافية للتحقق من فعالية هذه المواد في ظروف بيئية مختلفة. وأخيراً، يمكن أن تكون هناك حاجة لدراسة تأثير هذه المواد على البيئة المحيطة عند استخدامها بكميات كبيرة.

The biological role of chitosan which was prepared by chemical method from
shrimp waste Penaeus semisulcatus and the outer skeleton for marine crab Portunus
pelagicus in some industrial and agricultural applications were studied. The
concentration
of prepared chitosan was 1% (w/v) at pH (4 and 8) for 12 hours in
precipitation and chelating heavy metals (Lead, Zinc, Iron, Cupper and Cadmium)
from of sewage water. Concentration of elements was measured by Flame Atomic
Absorption Spectrophotometer ) FAAS). The results of the study indicated that the
concentration of the water elements was high before treated with chitosan. The
results showed a significant (p<0.05) decrease in element concentration percentage
after treated with crab chitosan. In contrast, shrimp chitosan displayed a minimum
effect on decreasing the amount of heavy metals. Moreover, the results showed that
the higher percentage for mineral adsorption was at pH (4 as compared with 8).
The results confirmed the possibility of using chitosan in chelate and precipitate the
mineral ions from polluted water.
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.
Multi-modal transport is a new legal transport system that aims to develop and activate the international transport of goods, it has become an essential part of the global supply chain which is essentially based on safety and quick delivery of the pr
oduct from producer to consumer through a combination of highly efficient operations and logistics services in various countries of the world.
This paper deals with the subject of multi-modal transport and the possibility applied in Lattakia port as it is the first container port in Syria. It also tries to describe the reality of Lattakia port, study and analysis the multi-modal transport elements as a network of roads and railways connecting the port inland areas and free zones to the neighboring states. The research also addresses the technological infrastructure in the container terminal of Lattakia port and focuses on the work of the customs administration, as the reform of the customs work and automatization of the fundamental factors are important for the establishment of an effective multimodal transport. Based on the results, the research presents some recommendations to activate the multi-modal transport and make Lattakia port an essential link in the logistical chain of regional and international transport.

evaluate the optimum pH, dosage and performance parameters
for coagulants,.We studied the effect of AL2(SO4)3·18 H2O,
,FeSO4.7H2O dosage on reducing of turbidity, The influence of
pH on turbidity reducing , and the effect of slow mixing time
on turbidity .
And turbidity reducing by AL2(SO4)3·18 H2O was removed 96
% of the total turbidity.
And turbiditu reducing by FeSO4.7H2O was removed 98 % of
the total turbidity.
Maritime transport is considered to be one of the most liberal and open industries having really complicated and sophisticated market systems. This sector is prominent in international spread and intensive in capital.
It significantly contributed to
the development of international
economy in general and to economic globalization in particular.
Maritime transport is known for embracing almost all new trends in information technology and telecommunication in which they have become the basic features that characterize the global maritime transport sector and essential factors to enhance and upgrade the capacity of seaports due to maritime need to speed in shipping and the follow up of shipments across the countries as well as accuracy and safety in the completion of loading and unloading inside the ports.
