دليل تصميم محطات معالجة مياه الصرف
يتناول هذا الكتاب جانبين هامين، أولهما : ضرورة الاستفادة من مياه الصرف في البلدان التي تقع في المناطق الجافة والقاحلة من العالم حيث تكون موارد المياء الطبيعية شحيحة والحاجة ماسة لتوفير أي قدر ممكن من المياه للاستخدام العام ولري المزروعات، وثانيهما : ضرورة معالجة النفايات البشرية بشقيها السائل والصلب لمنع التلوث ونقل الأمراض وانتشار الروائح الكريهة، ويتناول هذا الكتاب إحدى التحديات التي تواجه العالم النامي نسبة للزيادة السكانية المستمرة والانتقال من الريف إلى الحضر وما يتبع ذلك من زيادة كبيرة في كمية النفايات البشرية السائلة والصلبة التي لا تستطيع المدن استيعابها دون معالجة.

Determination of Heavy Toxic Metals \Pb, Cr, Co and Cd\ and Total Dissolved Solids in Purified drinking Water Plants in AL-Marj City in 2020
The purpose of this study was to determine the levels of heavy metals and total dissolved solids in purified drinking water plants in AL-Marj City. The studied water samples were randomly collected from different plants. The levels of heavy metals were that determined by flame atomic absorption spectroscopy (Flam AAS) instrument, at the same time, the total dissolved solids (TDS) were also detected by TDS meter. The obtained results showed the appearance and contamination of the most tested samples by toxic heavy elements via Pb, Cr, Co, and Cd. Additionally, the results showed that most of the samples suffer from losing total dissolved solids, which are important to human health. The results showed that most samples of water had greater levels of toxic heavy metals and lower content of total dissolved solids (TDS) than the standard values mentioned by the World Health Organization (WHO) and Libya Health Organization (LHO). Therefore, the study recommended that decision-makers in the city should be taken more care about purifying drinking water plants with monitoring and checking, comparing with the standard level of the Libyan Health Organization.

Investigation of a Modified Treatment Method of Industrial Wastewater in GIAD Factory
This study aims at solving the pollution problem in one of the industrial factories of GIAD manufacturing chemical compound. For dealing with this problem, a lab scale wastewater has been designed to recycle water. To extract the dissolved Na2SO4 and NaNO3, raw materials (activated charcoal, Na2SO4, NaNO3, two gas cylinders of H2 and CO were used. The experiments were prepared and carried out by mixing charcoal with water which contains Na2SO4 & NaNO3 and adding mixtures of gases containing (CO and H2) inside conical flask under temperature of 35°C. Three tests at different times were performed. Each test consisted of five results which were read and tabulated and three flowcharts were plotted from the obtained data. A process is described whereby sulphate is reduced to sulfide. Nitrate was converted to ammonia in the anaerobic reactor. From the obtained results the lab scale plant was scaled up to industrial size as a solution for the main problem. So it is highly recommended to construct the designed treatment plant to purify the wastewater station

خطة التسويق الإستراتيجي
يعتبر التخطيط الاستراتيجي الأساس في فرض القضايا التي تواجه إدارة المنظمة، والتخطيط يبدأ بوضع الرؤيا والمهمة وقيم المنظمة ومن ثم وضع الخطط للأنشطة المطلوب إنجازها انطلاقا من هذه الرؤيا والمهمة مع الالتزام بتلك القيم، وعليه فإنه يحدد توجه الإدارة لتحديد الأهداف الممكنة التطبيق في ضوء تأثير مختلف العوامل ذات العلاقة بالمنظمة. التخطيط الاستراتيجي ما هو إلا تلك العملية التي يتم من خلالها وضع مجموعة من الأهداف التي تترجم مهمة ورؤيا المنظمة لما تريد أن تصل إليه.
