Ask ChatGPT about the research

Resulting backwash water from existing filters, in the water purification plants, is actually thrown in most cases in water bodies, valleys or discharged into other system without making any benefit from it. The amount of backwash water is well estimated to be in average (3-4%) of purified water amount. Even if this amount is generally not relevant, it can however be considered to be useful in some circumstances, where the source water is rare or there is no water resource in the region at all. Treatment of backwash water depends on the reuse need of it, either for drinking or irrigation purposes, so that the treated water must be in accordance with the water quality standard stated in related specifications. In this research, the resulting backwash water purification plant at Roum Dam near Swaida town has been scientifically analyzed and treated in a plant designed and built for this purpose. In this paper, the results of experiments are discussed; important facts have been concluded and economic feasibility for water reuse was determined.

Research summary
تتناول هذه الدراسة مشكلة هدر المياه الناتجة عن غسيل المرشحات في محطات تنقية المياه، حيث تُلقى هذه المياه في المصادر المائية أو محطات الصرف الصحي دون أي استفادة منها. تهدف الدراسة إلى تحليل ومعالجة مياه الغسيل العكسي للمرشحات الناتجة عن محطة تنقية سد الروم في السويداء، وتحديد الجدوى الاقتصادية لإعادة استخدامها لأغراض الشرب أو الري. تم إجراء تحاليل علمية على مياه الغسيل العكسي، وتمت معالجة هذه المياه في محطات التنقية المصممة لهذا الغرض. أظهرت النتائج أن معالجة مياه الغسيل العكسي يمكن أن تكون مجدية اقتصادياً وتساهم في توفير كميات كبيرة من المياه، خاصة في المناطق التي تعاني من شح المياه. كما تم دراسة وتصميم نماذج لأحواض الترسيب لتحديد الأنسب منها لمعالجة مياه الغسيل، وأظهرت النتائج أن حوض الترسيب الدائري الأفقي هو الأكثر كفاءة. توصي الدراسة بضرورة إجراء تجارب دورية لتحديد الكميات المثلى من المواد الكيميائية المضافة لتحسين نوعية المياه وتقليل استهلاك المواد الكيميائية.
Critical review
تعتبر هذه الدراسة خطوة مهمة نحو الاستفادة من مياه الغسيل العكسي للمرشحات، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين دراسة مقارنة بين تقنيات معالجة مختلفة لتحديد الأكثر فعالية من حيث التكلفة والجودة. ثانياً، لم تتناول الدراسة بشكل كافٍ التأثيرات البيئية المحتملة لإعادة استخدام مياه الغسيل العكسي، وهو جانب مهم يجب مراعاته لضمان استدامة الحلول المقترحة. ثالثاً، كان من الممكن توسيع نطاق الدراسة ليشمل محطات تنقية أخرى في مناطق مختلفة من سوريا للحصول على نتائج أكثر شمولية. وأخيراً، ينبغي التركيز على تطوير تقنيات معالجة مبتكرة تتطلب أقل كمية من المواد الكيميائية، مما يقلل من التكلفة ويحسن من جودة المياه المعالجة.

The research aims to determine the water Quality Index for the Lake of 16 Tishreen Dam. To achieve this aim, we have carried out different periodical physic-chemical and bacterial measurements on the lake water. The samples were taken at five sites along the lake for a period of one complete year. The indicators that have been measured are: Temperature, Turbidity, PH, EC, DO, BOD5, NO3, NO2, NH4 ,PO4, F.C. Measurement results were represented diagrammatically, and compared with the Syrian Specification Standards for portable Water. The lake was classed according to these Indices: Malays quality index, Canadian Indices (NSFWQI), (NEWWQI). The Lake was Classed according to these indices as following: from third grade at all locations (Malays Index), from second grade at the middle lake and from a third grade to all other locations (NSFWQI), and from second grade at all locations (NEWWQI). According to this indices the water is not good for drinking and needs treatment. The Productivity of the lake was determined. The Lake is Eutrophic according to TN,TP in the middle but Hypertrophic according to TN,TP in all other locations.

This study was achieved through Mars 2011 until February 2012 the samples collected monthly from Baksa dam from different four location which differenced each other with chemical and physical qualities. We could in these study classified 132 speci es of phytoplankton distributed as 59 species belong to chrysophyta, 40 species of chlorophyta and 28 species of cyanophyta , 5 species of Euglenophyta. Physical and chemicalanalyzing ofBaksa waters showed the difference of values between studding regions, The concentration of Nitrate ions ranged between 17.7 mg/l at third location and 0.3 mg/l at second location, The highest rate to Phosphate ions was 18.8 mg/l and the less was 0.01mg/l, and it was noticed the difference in these values in the same region with the difference of period of time. The diversity and distribution of studied phytoplankton correlated with the environmental factors. It was noticed The abundance of cyanophytain the water of third location which near to the sewage channels which is suitable environment to these group of phytoplankton.
Modelling the relationship between drinking water turbidity and other indicators of water quality in Al-Sin drinking water purification plant using Dynamic Artificial neural networks could help in the implementation of the stabilization for the per formance of the plant because these neural networks provide efficient tool to deal with the complex, dynamic and non-linear nature of purification processes. They have the ability to response to various instant changes in parameters influencing water purification. In this research, four models of feed-forward back-propagation dynamic neural network were designed to predict the effluent turbidity from Al-Sin drinking water purification plant. The models were built based on turbidity, pH and conductivity of raw water data while the effluent turbidity data were used for verify the performance accuracy of each network. The results of this research confirm the ability of dynamic neural networks in modeling and simulating the non-linearity behavior of water turbidity as well as to predict its values. They can be used in Al-Sin drinking water purification plant in order to achieve the stabilization of its performance.
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 .
