Abstract

An Intermittent Cycle Extended Aeration System (ICEAS) offers advantages for treating sewage; such as easy operation, process flexibility, and low capital cost. The laboratory bench scale experiments were carried out treating domestic wastewater of Basrah City in fabricated ICEAS reactor of 72 L working volume. The domestic wastewater has the following characteristics (average values) pH= 7.5, Biochemical Oxygen Demand BOD= 200 mg/L, Chemical Oxygen Demand COD= 410 mg/L, Total Phosphorus TP= 7 mg/L, Total Suspended Solid TSS= 272. The aim of this research was to evaluate performance of the ICEAS system for treating domestic wastewater. Experimental results showed that the efficiency of ICEAS reactor to remove COD, Ammonia, TN, and TP were 91%, 83%, 60%, and 72%, while SBR efficiency were 87%, 81%, 58%, 69%, respectively. So, removal efficiency of ICEAS reactor was slightly higher than SBR. Comparison the effluent quality of ICEAS reactor with WHO, European and China discharge standards into surface waters were explained that COD concentration (37 mg/L) was meet to all standards (including Iraqi standard), while Ammonia NH3-N (7.87 mg/L), Total Nitrogen TN (17.16 mg/L) and TP (2.84 mg/L) were to European and China but not meet to WHO standard with slightly differences.

Abstract

We conclude from the research that the human soul has received great attention from the Sunnis. We note how the research began by mentioning the conversations that confirm the brotherhood and taking into account the feelings of others and their impact on social psychological harmony and its basis that establishes its existence. It was followed by a means of psychological influence on one, Its importance and role on the emerging in the consolidation of positive concepts, and also addressed the model of the conversations we extracted, including the impact that arises when attention to people and listen to them and not underestimated, the fact that listening to others is an art in itself is very influential in strengthening the bonds of society, and building bridges of communication between them, The study of warning conversations of two qualities affect the self and reduce the self-development of arrogance and anger and indignation, and showed their social impact and treatment and eliminate their causes and leave what is called for them, the research came as a means of self-treatment in the year.

نخلص من البحث بأنّ النفس البشرية قد نالت من السنة اهتماماً كبيرة ، إذ نلحظ كيف بدأ البحث بذكر الأحاديث التي تؤكد الأخوة ومراعاة مشاعر الآخرين وأثرهما في الإنسجام النفسي الاجتماعي ، وقاعدته التي ترسخ وجوده، ثم اعقبها بوسيلة من وسائل التأثير النفسي على المرء وهي القدوة ، وبينا اهميتها ودورها على الناشئ في ترسيخ المفاهيم الايجابية لديه ، وتناول أيضاً انموذج لأحاديث استخرجنا منها الأثر الذي يبرز عند الاهتمام بالناس والاصغاء لهم وعدم استصغارهم، كون الإصغاء للآخرين هو فن بحد ذاته له بالغ الأثر في تقوية أواصر المجتمع، وبناء جسور التواصل بينهم، وختمت البحث بأحاديث تحذير من صفتين تؤثر على النفس وتحط من رقيها الذاتي وهما التكبر والغضب المذموم ، وبينت أثرهما الإجتماعي وعلاجهما والقضاء على أسبابهما وترك ما يدعو إليهما، فجاء البحث كوسيلة لعلاج النفس في السنة .

Abstract

The ability of various soaking media in enhancing the temperature of waste materials, once they are exposed to microwaves has been investigated. Such information helps development of microwave techniques to destroy viruses, spores and other microorganisms by temperature enhancement if they may not be affected by microwave radiation itself. Oily media were observed to have higher elevation in temperature; however, they have the inherent drawback of sticking into the inner surface of the container. Such drawbacks can be minimized by using enclosed non-stick container for the microwave application.Among aqueous fluids, commonly found detergent solution showed the best performance in raising the temperature. Such material has many other advantages such as, low cost, non-toxic nature, environment friendliness, ready availability etc.
