Abdelsadig, Rami Anwar Osman; Supervisor, -Tyseer Yhya Moustafa Ali
The study objective dealt with evaluating the water quality of Bahri water purification plant. To achieve set goals, the results of the analysis of treated water were recorded for one year from the first of July 2021 until June 30, 2022. The importance of the study is that plant is considered the largest water production plant in the Republic of Sudan, as it produces 300,000 cubic meters per day. It invades many areas of the triangular capital, Khartoum. The study concluded that all the chemical elements conform to the specifications, but the turbidity of the water of the plant does not match the specifications, as well as the amount of residual chlorine, which caused the presence of coliform bacteria in some of the results of the analysis. The solution to the problem lies in the provision of purification materials such as poly aluminum chloride, PAC, as well as disinfection materials such as chlorine in sufficient quantities.

The objective of this study is to determine the pollution loads (both hydraulic and organic) emanating from the factories under the study (food processing factories). Field observation, interviews of the concerned personnel, and laboratories analysis as study tools. The determined loads are relatively high (hydraulic load, organic load) for each of the two factories and don’t agree with the recommended Khartoum north local order (1970) and SSMO (173/2008) standards. The results of samples analyzed for CAPO factory: were:
pH =6.89, TSS = 1000 mg/l, BOD = 4500 mg/l ,COD = 5650 mg/l and oil and grease = 150.100 mg/l. Wastewater flow = 5000 m3/day.
Results for EL mosharf factory: were:
pH = 6.55, BOD = 5516 mg/l, COD = 6825 mg/l, TSS = 350 mg/l.
Wastewater flow = 74 m3/day.
Neither of the two factories is having pretreatment facilities in spite of the need for it.
There is neither inspection nor flow measurement by KSSC for quantity and composition of the industrial wastewater generated.
It is recommended to install pretreatment facilities for the factories industrial wastewater in this plant, so as to be in line with the regulations
The proposed pretreatment unit designed for CAPO Plant as follows:
Q design = 208.33 m3/d, BOD design load = 124 kg/d, design TSS load= 144 kg/d.
Volume of lift station = 1000 m3, manual bar screen length =1.2m, width = 0.5 m, height = 0.5 m.
Volume of aeration tank = 6944.44m3.

The environmentally adequate disposal of oily wastewater is a current challenge to the petroleum industry. Currently, more consideration has been focused on the treatment techniques of oily wastewater. Therefore, oily wastewater treatment has become an urgent problem, and it must be explored and resolved by every refinery company. Oil refinery wastewaters contain many different chemicals at different concentrations for example: ammonia, sulfides, phenol and hydrocarbons. The study considered Khar-toum Refinery as study area, treated wastewaters were qualified using standard la-boratory tests for the following properties: Phenol Content, Ammonia Nitrogen, Suspended Solids, Sulfide content, Chemical Oxygen Demand(COD) and Biological Oxygen Demand (BOD) , the average results of oxidation pond (discharge point) samples were compatible withthe Sudanese Standardsand the Chinese standards in: Phenol Content which is reduced to 0.2 mg/l; Ammonia Nitrogen is reduced to 1.7 mg/l .However, the results were in agreement with one of the two standards ,sulfides is reduced to 7.6 mg/l , Suspended Solids value are reduced to 43.3 mg/l,Biological Oxygen Demand is reduced to 33.3 mg/l, Chemical Oxygen Demand is reduced to 142.7 mg/l. The results obviously showed the effectiveness of the treatment methods adopted by the Khartoum Refinery for decreasing levels of the contaminants in dis-charged wastewaters to meet the standards. More research and development workare recommended to adopt new combined treatment processes for Khartoum Refinery wastewater, to maximize the efficiency while decreasing cost of treatment.

Adam, Sarah EL Fadil Ali; Supervisor, -Ahmed Hamed Ibrahim Elfaig
This study focuses on analysis and control procedures of air pollution at Khartoum Refinery Company (KRC). The study aims at analyzing, discussing and assessing the level of emitted gases such as sulfur dioxide (SO₂), hydrogen sulphide (H₂S), carbon monoxide (CO) and nitrogen oxides (NO, NO₂, NOx). It also shows the control procedures followed by KRC to reduce the emitted gases and their impacts. The study was carried out from 1st January 2018 to 22nd May 2018. Sophisticated measuring devices running continuously are used to measure the levels of such gases. The study points out that the level of sulfur dioxide was (0 mg/m³); hydrogen sulphide was (0 mg/m³); carbon monoxide was (0.4061 mg/m³); and nitrogen oxides was (0.0001 mg/m³). It was also found that the measurement procedures of gas emissions taken are with accordance to Sudanese Standards and Metrology Organization (SSMO). The study found that the levels of the measures gases are within the range specified by Sudanese Standards and Metrology Organization (SSMO).
The study recommends that the existing levels of gases emission should be sustained. The study further recommends that improving awareness of local community is also seen as an important step in exposure to such gases.
