An Attempt to Find Suitable Parameters for Coagulation-Flocculation Processes for the Treatment of Water

تعتبر عكورة المياه من المحددات الفيزيائية المهمة لقياس نوعية المياه كونها مؤشر جيد لتحديد المعالجة المطلوبة لمياه الشرب.في الدراسة الحالية ,فحوصات الجرة القياسية ستجرى للحصول على افضل المحددات لتصميم عمليات التخثير- التلبيد.اثبتت النتائج بأن افضل زمن للخلط السريع (t1),  ولزمن الخلط البطيئ  (t2), ولزمن الترسيب (t3)   كان  1, 50 ,60 على التوالي اذ ان اعلى كفاءة ازالة للعكورة كانت (99.31, 98.56 , 94.72)% لزمن خلط سريع مقداره 5 دقائق وزمن خلط بطيئ مقداره 50 دقيقة وزمن ترسيب مقداره 60 دقيقة لقيم حامضية تتراوح (3.7 - 8.9). تم تمثيل القيم المقاسة لنسب ازالة العكورة بأستخدام تقنية الشبكات العصبية الصناعية ...اذ اوضحت النتائج تقارب جيد بين القيم المقاسة والقيم المخمنة بقيمة معامل تحديد (R2) وقيمة معدل الخطأ  0.932 , 0.5501 على التوالي.Water turbidity is considered as an important physical parameter of water quality. It is a good indicator for assessing the required treatment for the drinking water. In the present study, a standard jar tests were conducted to obtain the most suitable parameters for the design of coagulation-flocculation process. Results proved that the best rapid mixing time (t1), slow mixing time (t2), and settling time (t3) are 1, 50 and 60 min respectively. The maximum removal efficiencies of turbidity were 99.31, 98.56 and 94.72% at t1,  t2 and t3 equal to  5, 50 and 60 min respectively, with pH values ranged from 3.7 to 8.9. The measured values of water turbidity removal perecentage were represented using an artificial neural network (ANN) technique and the results signified that there is a remarkable agreement between experimental and predicted values with coefficient of determination (R2) and root mean squared error (RMSE) equal to 0.932 and 0.5501 respectively

Removal Turbidity of Water by Application of Electromagnetic Field Technology

Human and which serves to preserve the resource at the science forefront. Water of electromagnetic is old but addressed to popular the quantity of contaminants in a new way. The current study presents results related to the influence of an electromagnetic field (EMF) on synthetic water with $Al_2Si_2O_5(OH)_4$ (represented by Turbidity). The impact of an EMF as the only factor or as an intensifying element in stainless steel packing systems that limits pollutant concentrations in the treated water was analyses. The system that combined simultaneously stainless steel filling was most efficient. The electromagnetic treatment unit was designed and constructed for testing the treatment of syntheses water having turbidity. The influence of two variables on the efficiency of contaminant elimination during the function of the electromagnetic treating unit was checked. A significant dependence between the kind of system used reactor diameter and number of electrical coil windings were observed. The results showed that the PH values remain constant with EMF. The performance of the unit is determined by turbidity, the result shows greatest efficiency removal with 99.99% at the minimum diameter (2.54 cm), 99.99% in three reactors with three different numbers of coil turns
