Monitoring and Analysis of Tabuk Sewage TreatmentPlant

摘要

The increasing need for water in the arid areas of the world has resulted in the emergence of wastewater application for agriculture and landscape. This study aims to determine the mechanism and the functioning of waste water purification plant in the city of Tabuk, and see if the water was purified by the station impacted positively on the environment surrounding human beings, as well as determine if we can re-use the treated water in the various human uses. The objective of this research was to establish the operational parameters of Influent and effluent such as temperature, pH, TSS, biochemical oxygen demand (BOD), chemical oxygen demand (COD), dissolved organic carbon (DOC), TN, TP, and oil & grease (O&G). Three years of data (2010-2012) were manually collected at both the inlet and outlet. The results indicated that the pH was in between 6.213 to 7.493. Municipal wastewater showed that the TSS, BOD and COD were within the Saudi standards.It was revealed from the performance study that efficiency of the treatment plant was good with respect to removal of parameters like total suspended solids, BOD and COD. The overall performance of the wastewater treatment plant effectively removed TC, FC, and FS. The treated effluent can be safely discharged or it can be reused for irrigation of a fodder crops, golf course, green way, parks, for landscaping and for groundwater recharge. This work has confirmed that, the plant efficiency is comparable to that of other Saudi’s wastewater plants using the same or different type of biological treatment. Finally, based on this analysis, we proceed to identify niches in which wastewater reuse could be increased.
