Design your own MBBR with a handy calculation tool
Bacteria in the Moving Bed Biofilm Reactor convert nitrates to nitrogen gas. To have this denitrification process as optimal as possible, it is important to create ideal conditions to accommodate the bacteria: i.e. enough food and pleasant temperatures. The happier the bacteria, the better the conversion rates!
Therefore, an optimal design of the MBBR reactor is important to ensure high removal efficiencies ranging between 60 to 90%. KU Leuven developed the MBBR design tool to assist you with the correct dimensioning of your reactor. It is an Excel spreadsheet which needs to be completed with information about amongst others the influent nitrate concentration, the water temperature and the flow. Based on this input, the reactor volume and the carbon dosing rate will be calculated.
