Redefining Maximum Achievable Mixed Liquor Suspended Solids Concentrations in Membrane Bioreactors: Introducing Dissolved Oxygen in Membrane Bioreactors by Means of an Innovative Delivery Technology

The oxygen transfer efficiency in the aeration process plays a large role in determining the size and footprint of MBR equipment. Higher concentrations of MLSS tend to restrict the oxygen transfer process when using a conventional fine or coarse bubble process. The Supersaturated Dissolved Oxygen Injection System (SDOX) significantly increases oxygen transfer, is not affected by MLSS concentrations, requires less energy, and requires less footprint than conventional fine/coarse bubble systems.
