To calculate the required quantity of MBBR (Moving Bed Biofilm Reactor) media in an aerobic tank, you need to consider the following factors:
1. Tank volume: Determine the volume of your
aerobic tank in cubic meters (m3). This can be
calculated by multiplying the length, width, and
height of the tank.
2. Fill fraction: The fill fraction refers to the
percentage of tank volume occupied by MBBR
media. It typically ranges from 30% to 70%. Choose a
fill fraction based on your specific requirements and
system design.
3. Specific surface area: The specific surface area is a
measure of how much surface area is available for
biofilm growth on the MBBR media. It is usually
provided by the manufacturer and expressed in
square meters per cubic meter (m2/m3).
Once you have these values, you can use the
following formula to calculate the required quantity
of MBBR media:
Required Quantity (in cubic meters) = Tank Volume
(in cubic meters) x Fill Fraction x Specific Surface
Area
It's important to note that these calculations provide
an estimate and should be verified with the
manufacturer's recommendations or engineering
guidelines specific to your system design.
