Post-Anoxic Denitrification Process Design Calculations Process design of a post-anoxic denitrification MBBR system requires sizing an MBBR tank for BOD removal, one for nitrification, and one for denitrification. For all three of these reactors, the key design parameter for sizing the MBBR tank is the surface area loading rate (SALR), typically with units of g/m2/day, that is g/day (of the parameter being removed in that reactor) coming into the MBBR tank per m2 of carrier surface area in the reactor. Using design values for wastewater flow rate and concentration of the removed parameter entering the MBBR tank, the loading rate in g/day can be calculated. Then dividing the loading rate in g/day by the SALR in g/m2/day gives the required carrier surface area in m2. The carrier fill %, carrier-specific surface area, and carrier % void space can then be used to calculate the required carrier volume, tank volume, and the volume of liquid in the reactor. A typical flow diagram for a post-anoxic denitrification MBBR process is shown in the figure on the next page
