Membran biyoreaktör sistemlerin modellenmesi

As a result of the ever-increasing the world population, declining fresh water source has given rise to the need for conservation management of wastewater more efficiently. Accordingly, it has increased the need of wastewater reuse applications. Especially due to the benefits of the low space requirement and nutrient removal, the important of the membrane bioreactor (MBR) has emerged. Obtaining better quality effluent with the expansion of membrane bioreactor, wastewater can be reused and accordingly, fresh water sources can be protected more effectively. It is obvious that the increase in the efficiency of wastewater treatment with the use of membranes in the biological processes provides an important contribution to the protection of water sources. To achieve targeted results with the use of membrane bioreactor processes, system design and determination of the optimum operating parameters have a great importance. For this reason, the issues that must be considered for membrane bioreactor design are investigated and the design phases described in this study. The bioreactor design was made according to the ATV-DVWK-A 131 E design criteria for the municipal wastewater. The required bioreactor volume and oxygen demand were calculated according to the different MLSS, SRT and Recycle Ratio and the results were compared for integrated and separated MBR system. Consequently, examining the effects of the some important parameters on the operational of membrane bioreactor system were tried to determine.
