Advanced Wastewater Treatment with Membrane Bioreactors (MBRs)
Membrane bioreactors (MBRs) offer a cutting-edge system for advanced wastewater treatment. MBRs merge biological treatments with filtration processes to achieve high levels of clarification.
Typically, an MBR consists of a vessel where microorganisms break down organic pollutants in the wastewater. A thin-film membrane then filters the treated water from the biomass, resulting in highly purified effluent. MBRs are known for their potential to remove a diverse array of contaminants, including organic matter.
Furthermore, MBRs offer benefits such as:
* Reduced footprint
* High effluent quality
* Adaptability in setup
