This research aims to study the effect of some operation variables like (air flow rate, speed of mixing, temperature, acidic function ( pH ) , and dilution rate of alcohol ) , on acetic acid production. The operation conditions that worked are (air flow rate ( 1 - 4) m3 / hr ) , speed of mixing( ( 50 - 400) rpm ) temperature (( 18 - 33)C? ) , and dilution rate ( ( 0.005 - 0.02) hr - 1 )). The optimum operating conditions to produce acetic acid by continuous process are as follow : (air flow rate ( 3 m3 / hr ) ,speed of mixing (100 rpm) , temperature ( 30 C? ), dilution rate of alcohol(0.005 hr - 1) initial alcohol concentration ( 48 g / l ) and initial concentration of acetic acid ( 40 g / l ))..

Abstract: تهدف هذه الدراسة الى ايجاد تاثير المعالجة الكيمياوية بطريقة الترسيب الكيمياوي على كفاءة ازالة العناصر الثقيلة في مياه الفضلات الصناعية المطروحة لتصل الى النهر بالتراكيز المسموح بها. تتم عملية الترسيب الكيمياوي بالسيطرة على الدالة الحامضية لمياه الفضلات ب | This study aims to find the effect of chemical treatment by chemical precipitation on the efficiency of removing heavy metals from wastewater to be poured back to the river. Chemical precipitation is done by controlling the (PH) of wastewater by adding a suitable hydroxide ,different hydroxides were used like the hydroxides of sodium ,calcium and potassium 0.05N each and sodium carbons 0.1N in removing heavy metals of wastewater. The study has taken prepared samples contain different concentrations of heavy metals ions like cupper 2,4 and 6 ppm zinc 5,10 and 15ppm and manganese 2,5,8 ppm Jar taste is used to show the chemical precipitation. Fast and slow mixing periods were written down to get the velocity gradient (G) and (GT) The used materials were highly efficient to remove the ions of metals. The removed amount of metals was measured by (AAS) Atomic Absorption spectroscopy. The paper has also studied the effective factors on the efficiency of precipitation like the (PH) is (8,9,10,11) and The precipitation time is (0.5,1,2,3)h.The result show that the best precipitation efficiency when an ion is used alone in the solution (PH) is (10,11) precipitation time 2h hydroxides precipitation (0.05N) it removes about 98% of cupper ions when sodium and calcium hydroxides are used ,more than 96,66% when the potassium hydroxide is used.a complete removing appears of manganese ions when the calcium hydroxide is used more than 90% when the potassium hydroxide is used.77% when the sodium hydroxide is used more than 98.4% of zinc ions removed when the sodium and calcium hydroxide is used 95.9% of zinc ions is removed when the sodium carbons are used the best treatment condition appear when the (PH) is (9 to10) and precipitation time is 2h when an ion is used alone in the solution 98% of cupper and zinc ions are removing 90% of manganese ions.When the ions are mixed in the solution the best removing efficiency appears when the (PH) is (9 to 11) and precepitition time is 2h when the hydroxides and carbons are used a complete removing of cupper ions 90% of zinc ions and more than 98.2% of manganese ions.The time of reaction to get 10.5 PH using hydroxides is (25 - 30) second when sodium carbon's are used the reaction time to get 8.5 is (50) second for cupper and zinc ,(25) second for manganese.The reaction is zero order when hydroxides are used and first order when carbons are used in treating heavy metals.

Abstract: ان هدف الدراسة الحالية هو ازالة البنزين والفينول والباراكلوروفينول من مياه الصرف الصناعية في مصفى بيجي بعملية الامتزاز بواسطة الكاربون المنشط الحبيبي وامكانية تمثيل العملية بنموذج رياضي.وقد صمم وصنع جهاز مختبري لغرض انجاز الدراسة اخذين بالاعتبار امكاني | The aim of the present study is to remove phenol, parachlorophenol and Benzene from waste water of Baiji refinery by using granular activated carbon. Moreover using the present models to represents the experimental data.A Laboratory scale apparatus is designed and constructed taking into account the most important parameters effecting adsorption. In performing the present study Actual wastewater of Baiji refinery is taken to perform the experimental work.The results indicated that phenol, parachlorophenol and Benzene can be removed completely using granular activated carbon. Also the results indicated that breakthrough and exhaustion time are inversely proportional with the concentration of pollutants and liquid hourly space velocity, while they are directly proportional with the thickness of granular activated carbon. Its found that the Adsorption capacity is directly proportional with the concentration of pollutants and liquid hourly space velocity. The results of this work indicated also the thickness of adsorption zone, which is calculated depending on the result of this study, is directly proportional with liquid hourly space velocity.Application of the most famous available models that are used to represent adsorption phenomena on our experimental data show that only Freundlich model gives excellent agreement.In order to find mathematical model for breakthrough and exhaustion time as a function the most important parameters, an advanced computer program is used.We found two mathematical model for breakthrough and exhaustion time as a function of granular activated carbon thickness, liquid hourly space velocity and the concentration of pollutants. These two models give acceptable agreement with the experimental results.The adsorption capacity for the three pollutants are calculated and found to be directly proportional with liquid hourly space velocity and pollutants concentration.

Abstract: تعتبر عمليات التخثير والتلبيد والترسيب من اكثر العمليات شيوعا في معاملة المياه لغرض الحصول على مياه صالحة للشرب. ولتحقيق هذا الغرض نستخدم عدة مواد كيمياوية في مرحلة التخثير. يعتبر الشب من اكثر المواد شيوعا كمادة مخثرة. بينت العديد من الدراسات والبحوث ا | Coagulation, flocculation, and settling processes are the most important processes for water purification chemical materials have to be used for coagulation processes Alum is one of the most prevalent as a coagulation material many researches and studies explain that the Alum has a side effect causes a health problems and discuses for consumer, so it is necessary to search for alternatives. In our study we explain the usage of some alternatives of Alum, we choose the Starch, Dextrin, Okra seeds & Cactus oil as a natural coagulants, we test them within the range of initial turbidity from (30 - 500 NTU) and range of pH (from 5 to 10) and we found the best dose for each coagulant.We design and fabricate a laboratory Jar test device and use the Lamella settler for test these natural coagulants.We are made many experiments by using the Jar test and Lamella settler and when compared results found that the Lamella settler has a good settling efficiency.Results show that the efficiency of the Jar test (50 - 60%) and for Lamella settler (40 - 50%).
