This membrane bioreactor (MBR) has an open-source wastewater design that can operate MBR modules from different suppliers. It provides flexibility to switch from one membrane to another without having to redesign the treatment plant.
 
The flexMBR technology can be used in new systems, but can also be incorporated into an existing wastewater treatment system. The design gives system owners the flexibility to negotiate the price of their replacement membranes, and to possibly choose a different membrane model for replacement. With this open-source approach, replacement of modules becomes a more competitive process and is open to new module designs that may be developed in the future. This allows owners to take advantage of the latest technology and pricing options offered by different membrane manufacturers.
