Membrane Bioreactors for Wastewater Treatment to Produce Useable Water

Abstract

Membrane bioreactors (MBRs) are a cutting-edge treating wastewater technology which combine bioremediation of effluent with membrane technology of solids and liquids. MBRs have gained increasing attention in recent years due to their ability to effectively treat complex and high-strength wastewater streams and produce high-quality reusable water. In this review article, we examine the principles of MBR technology, its applications in the treatment of various effluents, and the advantages and limitations of the technology. We also discuss the current trends and future directions for MBR research and development. Modern membrane bioreactor technology has undergone a revolutionary change as a result of advances in water treatment technology. The old, activated sludge process’s high cost, low efficiency, and significant space demand have created the space required for the MBR system to function. Immersed and side-stream MBR can take the role of the traditional sludge procedure and tertiary filtering. The historical development of the MBR method for the treatment of municipal and industrial effluents is described in this study. The efficiency of the MBR process is greatly influenced by the structural characteristics and design parameters, such as membrane surface qualities, water flux, storage time, pH, alkalinity, temperature, and washing regularity.
