Membrane Bioreactor (MBR) - Benefits & Applications
MBRs are used in a large variety of applications, some examples are listed below.
Ultrafiltration membranes remove the majority of suspended solids particles and, consequently, replace conventional treatment, such as coagulation/flocculation, sedimentation, filtration, etc. The membrane's ability to retain bacteria, viruses, and microorganisms reduces the size of, or in some cases eliminates disinfection equipment.

  • Operation at higher MLSS => more robust process

  • Compact foot print

  • Lower waste sludge production

  • Fully automated operation => ease of operation and less operator attention

  • Easy upgrade and expansion by adding membrane modules - modular built

  • Sludge generated from the process requires less dewatering

  • Disinfection is reduced or eliminated

  • Provides consistent, superior effluent quality independent of flow variations (heavy rain), floating sludge, etc.

  • Effluent is reusable / recyclable

  • Removes chlorine-resistant Giardia and Cryptosporidium

  • On-lot treatment systems for single or multi family homes

  • Compact containerized package plants

  • Larger scale MBR plants using on-site concrete basins

  • Water reuse and recycling

  • Military camps - mobile package units 

  • Commercial users such as hotels and casinos

  • Industrial users such as food processing plants, etc.

  • Real estate developers

  • Shipbuilders

  • Small municipal communities

  • Areas that have enacted stringent wastewater effluent regulations

  • Sludge dewatering (up to 3%)

  • Industries forced to update current treatment facilities

  • Areas with dwindling water resources

  • Cleaning of pond water

  • Biological landfill leachate treatment

  • Process water treatment
