Advanced Wastewater Treatment with Membrane Bioreactors (MBRs)
Membrane bioreactors (MBRs) provide a cutting-edge system for advanced wastewater treatment. MBRs merge biological treatments with filtration processes to achieve high levels of purification.
Typically, an MBR consists of a tank where microorganisms consume organic pollutants in the wastewater. A thin-film membrane then removes the treated water from the biomass, resulting in highly purified effluent. MBRs are known for their ability to eliminate a broad spectrum of contaminants, including suspended solids.
