Abstract

As a viable solution for the treatment and recycling of sewage from residential areas, this research presents membrane bioreactors (MBRs) systems, both immersed and side-stream. These systems are offered as viable options. This study's objective is to analyse the overall performance of each membrane bioreactor in terms of its capacity to meet water reuse requirements. This will be accomplished with the assistance of water quality indices such as total suspended solids (TSS), biological oxygen demand (BOD), and chemical oxygen demand (COD). It is obvious from the data that the MBR system is capable of producing permeate water of a high quality and that the MBR technology is efficient in reducing total suspended solids (TSS). COD and BOD rejection rates in the submerged MBR were, on average, 92.76% and 94.46%, respectively. This was the case. Comparatively, the percentages of COD and BOD that were rejected in the side-stream MBR were 87.54 percent and 88.98 percent, respectively. It has been discovered through the examination of COD and BOD that the removal of the submerged MBR system is preferable to the removal of the side-stream MBR system.
