Drinking water is too neccessary for everyone .It must be pure and healthy.Turbidity is one of the most important problems in water .It may cause damage for humanbeings . So it must be controlled. This search aims to determine the suitability of dosing AL2(SO4)3·18 H2O, ,FeSO4.7H2O with the intention of reducing turbidity levels to acceptable limits . In the present study , a series of jar test was conducted to 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.

Research summary
تتناول هذه الدراسة كفاءة استخدام المخثرات الكيميائية في إزالة العكارة من مياه الشرب. تم استخدام كبريتات الألمنيوم المائية (الشبه) وكبريتات الحديدي كمواد مخثرة في تجارب مخبرية لتحديد الجرعات المثلى وتأثيرات pH وزمن التحريك على كفاءة إزالة العكارة. أظهرت النتائج أن كبريتات الحديدي كانت أكثر فعالية في إزالة العكارة بنسبة 98% مقارنة بكبريتات الألمنيوم التي حققت نسبة 96%. كما تبين أن إضافة ماءات الكالسيوم تزيد من كفاءة إزالة العكارة. تم تحديد الجرعات المثلى لكل مخثر عند قيم مختلفة من العكارة الأولية وpH، وأظهرت النتائج أن التحريك البطيء لمدة 15 دقيقة كان كافياً لتحقيق أقصى كفاءة في إزالة العكارة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في مجال تحسين جودة مياه الشرب، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين مجموعة أوسع من المخثرات الكيميائية والطبيعية لمقارنة أكثر شمولية. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية الأخرى مثل درجة الحرارة ونوعية المياه الخام على كفاءة المخثرات. ثالثاً، كان من الممكن توسيع نطاق الدراسة ليشمل تجارب ميدانية في محطات معالجة المياه الحقيقية للحصول على نتائج أكثر تطبيقية. وأخيراً، لم يتم مناقشة الجوانب الاقتصادية بشكل كافٍ، مثل تكلفة المواد المخثرة وتأثيرها على تكلفة معالجة المياه.

Proven chemical analyzes conducted in the summer of 2014 to thirty wells in the village AL-Shamia- Latakia region, that water wells west of the adjacent village to the seaside up to 300 m distance to the east where the salinity increases while decreasing the East Village to become water sweet near way of Lattakia-Kassab, at a distance of 1500 m fromn the sea beach.
Water sources in Syrian coastal area have a great importance due to the variety of the sources and the urgent needs to water for drinking and irrigation. Therefore great efforts are made to protect water sources from contaminants. This research aim ed to study some contaminant indicators in some drinking water sources in the Syrian coastal area. The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and zinc in water samples taken from five sources of water distributed from north Lattakia to north Tartous. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their relative purity and contaminants little reach.
This research focused on one of the stages of the conventional treatment of water in the purification stations, a process of coagulation, which enhanced by using alternatives to alum; such as Ferric Chloride and Poly Aluminum-chloride (PACl), whic h play an important role to reducing the turbidity of drinking water through the destabilization of colloids, which include organic and inorganic materials in order to increase the efficiency of sterilization and disposal of the side effects of sterilization (DBPS) and to minimize the problems of clogged sand filters due to an increase of the turbidity of water inside it. According to that, three types of coagulant agents were used for the purpose of comparison with each other to achieve the best efficiency in the process of reducing water turbidity through a process of coagulation improved by using (Jar-test). Different concentrations of coagulant agents of irrigation water were used depending on experiments. The results found that urinary chloride aluminum gave the highest efficiency in reducing turbidity by (84, 82 and 81%) according to the addition of concentration for coagulation (20 ppm, 10 ppm and 5ppm), respectively. The reduction rates in turbidity for Ferric chloride were (79, 78.2 and 78.1% ) by concentrations added, respectively, but for alum, the reduction rates in turbidity were (58, 56, and, 54%) by concentrations added, respectively.
Fluoride ion is present in high concentration in some regions in Syria. As fluoride occurs naturally in water, We have studied some methods of fluoride removal such as Nalgonda technique and activated carbon method. In Nalgonda technique we add Al um and lime to the water, and we have found that fluoride removal efficiency remains constant when the initial concentrations of fluoride changes, or when the chloride ions exists in water, but it depends on pH, and get better when the method is investigated in two steps. In addition, adsorption of fluoride decreases with increasing sedimentation time, or using Ventilated lime or CaCO3 instead of Ca (OH)2. In activated carbon method we have done different experiments by using charcoal of coconut coir, date seeds and olive seeds. And we have found that olive seeds carbon is better than others, and its fluoride removal efficiency increases after impregnation with solution of 2% Al2(SO4)3.
This research discusses the problem of drinking water shortage and distribution instability in Salamyeh city due to the current crisis. Salamyeh city dependents on Orontes River as a source for drinking water through Hama water supply facility, wh ich sufferes repeated sabbotage attacks. As a result, an emergency measure was implemented by depending on local water sources within the city, which are deep wells that produce water of sulphuric nature.Three desalination plants were provided to treat local sulphuric water producing suitable safe water, but these plants production is way less than the city needs.
