Membrane bioreactor (MBR) process has emerged as a prominent solution for wastewater treatment due to its ability to achieve high removal efficiencies of organic matter, nutrients, and suspended solids. MBRs integrate a biological reactor with a membrane separation unit, effectively combining the advantages of conventional activated sludge systems with ultrafiltration capabilities. The configuration results in the compact and efficient treatment process that produces high-quality effluent suitable for reuse or discharge into sensitive environments.

MBR technology consists several key components, including an aeration tank, a membrane module, and a recirculation pump. The biological reactor provides the environment for microorganisms to transform organic contaminants. The membrane module acts as a biological barrier, retaining suspended solids and microorganisms from the treated water.

Several factors influence the performance of MBRs, including membrane characteristics, operating conditions, and influent composition. Optimization of these parameters is crucial to achieve optimal treatment efficiency and system stability. MBR technology offers several advantages over conventional wastewater treatment methods, such as high effluent quality, compact footprint, and reduced sludge production.
