Huge quantity of produced water is salty water trapped in the oil wells rock and brought up along with oil or gas during production. It usually contains hydrocarbons as oil and suspended solids or turbidity. Therefore the aim of this study is to treat produced water before being discharge to surface water or re injected in oil wells. In this paper experimental results were investigated on treating produced water (which is obtained from Middle Oil Company-Iraq), through electrocoagulation (EC). The performance of EC was investigated for reduction of turbidity and oil content up to allowable limit. Effect of different parameters were studied; (pH, current density, distance between two electrodes, and electrolysis time). The experimental runs carried out by an electrocoagulation unit was assembled and installed in the lab and the reactor was made of a material Perspex, with a capacity of approximately 2.5 liters and dimensions were 20 cm in length, 14 cm in width and 16 cm height. The electrodes employed were made of commercial materials. The anode was a perforated aluminum rectangular plate with a thickness of 1.72 mm, a height of 60 mm and length of 140 mm and the cathode was a mesh iron. The current was used in the unit with different densities to test the turbidity removing efficiency (0.0025, 0.00633, 0.01266 and 0.0253 A/cm2).The experiment showed that the best turbidity removing was (10, 9.7, 9.2, 18 NTU) respectively. The distance between the electrodes of the unit was 3cm. The present turbidity removing was 92.33%. A slight improvement of turbidity removing was shown when the distance between the electrodes was changed from 0.5 to 3 cm with fixation of current density. The best turbidity removing was 93.5% , (7.79 NTU) when the distance between the electrodes were 1 cm. The experimental results found that concentration of oil had decreased to (10.7, 11.2, 11.7, 12.3) mg/l when different current densities (0.00253, 0.00633, 0.01266, 0.0253) A/cm2 were used, respectively with the distance between the electrodes was 3 cm. The best result of oil content decreasing was 10.7 mg/l with current density 0.0253 A/cm2. These results are within allowable limit to provide the possibility of reuse the water and can be injected in oil wells
The research aims to identify the organizational culture of the Angels and administrative technical staffs for teams participating in the West Asian Taekwondo Championship, and the التنظيمية الثقافة يف مقارنة دراسة والفنية االدارية املالكات بني املشاركة للفرق ...... 363 difference in organizational culture between the administrative staffs of art, and the level of the dimensions of organizational culture (cooperation, innovation, conssinon, efficiency) from the viewpoint of administrative technical staffs. Descriptive approach was used with survey, style the research sample consisted of (44) people (28) administrative and (16) art divided into four teams (Iraq, Jordan, Lebanon, Palestine To achieve the objective of this research the researchers used a questionnaire of organizational culture prepared by the (Alkhhali and Tamimi, 2008), where the questionnaire organizational culture (26) items distributed in to (4) areas:(cooperation, innovation, consistency, efficiency), and was processing the data statistically using the ratio percentages and the arithmetic mean, standard deviation and assumption mean alpha coefficient and (T) test. The researchers concluded the following: 1-the emergence of a high level of organizational culture reflects the importance of its elements from the standpoint of administrative and technical staffs of the participating teams in the West Asian Taekwondo Championship. 2-There are no significant differences in organizational culture between administrative staffs and technical staffs for the participating in teams in the West Asian Taekwondo Championship. 3-the emergence of variation in the levels of the dimensions of organizational culture (cooperation, innovation, consistency, efficiency) from the viewpoint of administrative and staffs for the participating in teams in the West Asian Taekwondo Championship where it came from levels of the dimensions of culture of management (cooperation, innovation, cohesion) high and (effective) is very high. While levels of the dimensions of culture came to the Angels art (collaboration, innovation) and high for (consistency, efficiency) is very high.
On 31 December 2019, pneumonia of unknown cause was detected in Wuhan, China, and was first reported to the WHO Country Office in China. On 30 January 2020, the outbreak was declared a Public Health Emergency of International Concern. 1
It was an outbreak of severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) infection that occurred in Wuhan, Hubei Province, China and got spread across China and beyond. WHO officially named the disease - Corona virus Disease 2019 (COVID-19) on February 12, 2020. 2
It has been spreading worldwide for a period of atleast a year & half 3 This review article addresses the current scenario caused by the SARS- Co V along with the treatment protocols and ongoing vaccines.
