The Membrane BioReactor (MBR) is a state of the art pre-engineered sewage treatment system utilizing Pure Aqua’s water treatment expertise with Toray’s submerged membrane technology. The membrane separation process eliminates the conventional sedimentation tank and allows high volumetric loading, resulting in a smaller footprint. The MBR can produce high quality effluent with high BOD5 removal (about 98%), complete nitrification and partial de-nitrification and achieves virtually complete TSS removal.
Membrane bioreactor (MBR) is composed of an exclusive wastewater treatment method created for many municipal and industrial applications with plant sizes that reach 48 million liters per day. Membrane bioreactor systems are designed to be used in applications such as water reuse, turnkey projects, new housing developments, retrofits, parks, and hotels. It comes between ultrafiltration or microfiltration with a suspended growth bioreactor. MBR claims two types of configurations: internal and submerged. Internal: membranes are immersed in and are an integral to the biological reactor. Submerged: membranes are a separate system method needing an intermediate pumping step.
Membrane bioreactor systems are practical solutions for existing and future wastewater treatments when it comes to the demand of recycling wastewater and stricter environmental regulations. MBR methods can generate effluent of high quality enough to be discarded to coastal, surface or brackish waterways or to be recovered for urban irrigation when being used with domestic wastewater. MBR claims other advantages such as small footprint, easy retrofit and upgrade of old wastewater treatment plants. MBR methods can be operated at higher mixed liquor suspended solids (MLSS) concentrations in comparison to conventional settlement separation systems, therefore, decreasing the reactor volume and achieving the same loading rate.
