In this study, iron chloride solution ١٠٪ was used as absorbance matter which absorbs all dyes and the organic substances during its precipitation . The accumulation of these wastes in nature is considered to be a serious source of pollution and health hazard. We determined the optimal pH and the optimal dose of a minimom number of the reagent used as well as the water of dyehouse baths, and we compared the difference between using iron chloride and aluminium sulfate .We adopted the experimental observation in measuring the results and the strength of absorption within the spectrofield in a wave length of ٣٥٠ – ٧٥٠ nanometer .

Research summary
في هذه الدراسة، تم استخدام محلول كلوريد الحديد كعامل امتزاز يمتص جميع الأصباغ والمواد العضوية أثناء ترسيبه. تراكم هذه النفايات في الطبيعة يعتبر مصدرًا خطيرًا للتلوث وخطرًا صحيًا. تم تحديد درجة الحموضة المثلى والجرعة المثلى لعدد قليل من الكواشف المستخدمة وكذلك مياه أحواض الصباغة، وتمت مقارنة الفرق بين استخدام كلوريد الحديد وكبريتات الألمنيوم. اعتمدت الدراسة على الملاحظة التجريبية في قياس النتائج وقوة الامتصاص ضمن الطيف عند طول موجي محدد. الهدف من البحث هو رصد هذه الملوثات والعمل على معالجتها للتخفيف من ضررها على البيئة. تم استخدام تقنيات مختلفة لمعالجة مياه المصابغ، بما في ذلك الامتزاز باستخدام رزينات التبادل الشاردي، الأكسدة باستخدام الماء الأكسجيني والأوزون، والمعالجة الحيوية باستخدام الأحياء الدقيقة. كما تم استخدام المعالجة الكيميائية بإضافة أملاح معدنية مخثرة ومرسبة، وتمت مقارنة فعالية كلوريد الحديد وكبريتات الألمنيوم في ترسيب الأصباغ والمواد العضوية من مياه المصابغ.
Critical review
دراسة نقدية: تعتبر هذه الدراسة هامة في مجال معالجة مياه المصابغ، حيث تقدم حلولًا عملية لتقليل التلوث البيئي. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة تعتمد بشكل كبير على التجارب المخبرية دون تقديم تحليل اقتصادي لتكلفة المعالجة باستخدام كلوريد الحديد مقارنة بكبريتات الألمنيوم. ثانيًا، لم يتم التطرق بشكل كافٍ إلى تأثيرات هذه المواد الكيميائية على البيئة على المدى الطويل. وأخيرًا، يمكن تحسين الدراسة بإضافة تجارب ميدانية لتأكيد النتائج المخبرية وتقديم توصيات أكثر شمولية لتطبيقها في الواقع العملي.

In this study, microorganism separated from the Syrian soil were used in treating the waste water from dyehouse and some dyes which are oftenly applied. A great difference was found in the speed of microorganism growth as well as the great variati on in color disappearance, in addition to inactivating the enzymatic work by some of the dyes. Also, the effect of the dyes density on the growth of microorganism. The absorption strength measurment in the field of visible spectrum between ٣٥٠ –٧٥٠ nanometers was adopted for analyzing the filtrates resulting from the biological treatment .
This study was conducted to determine the chemical and physical analysis of two important water sources in the coastal erea, namely: Northern Elkabeer river and Balloran Dam. The study took a year and a half starting from June ١٩٩٩. The temperatu re the cations and the anions were periodically determined in three sites selected along the river bed. Results showed, that there are a large variations in the concentrations of the studied elements, in both water sources. The same variations were also observed among the three defined sites of the same source according to the ruling climatic factors during the year. The increase in the concentrations of most of chemical elements in water source was observed when the temerature increased. These concentrations generally reach the highest value in the latest Summer and the beginning of Autumn. It was shown that the impact of the biogeochemical factors namely: rainfall and floods, the water drianing from soils and the effect of agricultural and in dustrial waste - water became clear . According to the international and Syrian standards of water chimical qualities, the water of Balloran Dam and ١٦ Tishreen Dam can be used for drinking and irrigation purposes. While water of the tow studied sites on the Elkabeer river can only be used for irrigoation.
The research has been conducted in different sites in lattakia, Alhamra and alsabahia villages of Rabea and Aen alzarqa of Mashqeta. 14 cases of precipitation was marked which caused runoff and water erosion of soil during the research (seasonal ra infall in 2011/2012). Samples of rain water of every precipitation case were collected. by using rain gauges that were installed in the research sites. After that, samples were moved to the laboratory. The pH was determined after that the samples were analyzed by using an ion chromatography device(IC).
This research was performed to study the effect of sewage water on the surface water of the Addelbeh Valley stream, and groundwater on both sides of the stream in Tartous Cement Factory area. Water samples were taken from the factory water outlet and Addelbeh Valley water to study the content of pollutants. We also took groundwater samples from selected wells on both sides of the waterway in the studied area. We repeated that process every two months for a full hydrological cycle from July 2013 to May 2014. We found a great increase in content of the industrial drainage water include oils and heavy metals especially iron, copper and zinc. For example: iron concentration in sewage water exceeded 150 mg/l in all samples. Besides sewage water and stream water contained high concentrations of ammonia and nitrite versus low concentration of nitrate, unlike water wells samples. The study revealed increased EC and salts concentration markedly in wells water due to its adjacency to the sea.
The present study contains results of some experiments that had been carried out to study the advantage of olive mill waste water (OMW) use ability and in sugar's factories wastes in Syria as fungi cultures to produce stall-feed rich in proteins. The results showed that Geotrichum rich in proteins had been grown and geminated more rapidly and revealed that inorganic nitrogen additions (nitrates or ammonia) to the culture have advanced the fungi growth which is rich in proteins, the highest quantity of proteins was (8.6 g/l) in NH4NO3 (1.5%) media and urea (2.0%) media whereas the fungi biomass was higher with NH4NO3 (1.5%) than with urea (2.0%).
