Description
In this spreadsheet, you will be able to design a two-stage MBBR (moving bed biofilm reactor) wastewater treatment plant including the following:
- Sizing a BOD removal tank 
- Sizing a Nitrification tank
- Generate the quantity of media needed in both tanks 
- Generate the aeration requirements for the BOD tank
- Generate the aeration requirements for the Nitrification tank
As support, you can refer to the following youtube video https://youtu.be/EhQWMNV6fMw which explains how the spreadsheet was designed and how to fill the values. You can also watch some educational videos about the MBBR technology on the same channel (technical description, design tools, step by step calculations,  etc...)
