Abstract (English): Water pollution is currently one of the most serious problems facing humanity. In this regard, making this natural resource usable and unpolluted is of great social and economic importance. However, eliminating organic pollutants has received special attention to purify water waste. Chemical coagulation procedures are used by determining the optimal speed and dose of coagulants required to remove turbidity and dye from an aqueous solution while fixing pH and temperature to optimal values based on previous research. Aluminum sulfate (alum) and ferrous sulfate Fe2 (SO4)3 were used. Alum was found less efficient than Fe2 (SO4)3. It has been found that reducing turbidity was more effective than removing pigment. Maximum turbidity (NTU) and decolorization of (88% and 83%), respectively, were achieved with an optimum dose of 30 mg/L at pH 11, a settling time of 50 min, and a stirring speed of 120 rpm. Maximum turbidity (NTU) and color removal of (84% and 81%), respectively, were achieved at an optimum dose of 30 mg/L at pH 8, a settling time of 50 minutes, and a stirring speed of 120 rpm. On the other hand, physical and chemical technologies can be used as a rapid and cost-effective treatment method in terms of the availability of materials used compared to other treatment processes.

Abstract (Arabic): بعد تلوث المياه حاليا أحد أخطر المشاكل التي تواجه البشرية. وفي هذا الصدد، فإن جعل هذا المورد الطبيعي صالحًا للاستخدام وغير ملوث له أهمية اجتماعية واقتصادية كبيرة. ومع ذلك، فقد حظي التخلص من الملوثات العضوية باهتمام خاص لتنقية مخلفات المياه، حيث يتم استخدام إجراءات التخثر الكيميائي من خلال تحديد السرعة والجرعة المثلى لمواد التخثر اللازمة لإزالة العكارة والصبغة من المحلول المائي مع تثبيت الرقم الهيدروجيني ودرجة الحرارة إلى القيم المثلى بناءً على الأبحاث السابقة. تم استخدام كبريتات الألومنيوم (الشب) وكبريتات الحديدوز . لقد وجد أن الشبة أقل كفاءة من كبريتات الحديد. لقد وجد أن تقليل التعكر أكثر فعالية من إزالة الاصباغ. تم تحقيق الحد الأقصى من التعكر وإزالة اللون (۸۸ و ۸۳) على التوالي مع الجرعة المثلى البالغة ٣٠ مجم / لتر لكبريتات الحديد عند درجة الحموضة ۱۱ ، وزمن الترسيب ٥٠ دقيقة وسرعة التحريك ۱۲۰ دورة في الدقيقة. الحد الأقصى للتعكر وإزالة اللون (٨٤) و (۸۱) على التوالي عند الجرعة المثالية البالغة ٣٠ مجم/ لتر للشبه عند درجة حموضة ، وزمن استقرار قدره ٥٠ دقيقة، وسرعة مزج تبلغ ۱۲۰ دورة في الدقيقة. ومن ناحية أخرى يمكن استخدام التكنولوجيا الفيزيائية والكيميائية كوسيلة معالجة سريعة وفعالة من حيث التكلفة وتوفر المواد المستخدمة مقارنة بعمليات المعالجة الأخرى.
