## Background for Membrane Bioreactor Wastewater Treatment Calculations Spreadsheet

A membrane bioreactor wastewater treatment system (MBR) can provide a compact alternative to the conventional activated sludge process. The MBR process uses filtration through a membrane instead of secondary clarification, so it produces a very high quality effluent. Primary clarification is not typically used in a membrane bioreactor wastewater treatment system. Fine screening is needed as a minimum pretreatment, and depending upon wastewater characteristics, coarse screening and grit removal may be needed also. The diagram below shows a general flow diagram for a MBR wastewater treatment system for BOD removal and nitrification.

Currently the membrane module is typically immersed in the aeration tank as shown in the flow diagram. Denitrification can also be carried out by adding a preanoxic tank before the aeration tank.

## Example Membrane Bioreactor Wastewater Treatment Calculations Spreadsheet

An example *membrane bioreactor wastewater treatment calculations spreadsheet *is partially shown in the image below. This Excel spreadsheet can be used to calculate the required volume and dimensions for the MBR aeration tank, membrane module, and preanoxic tank, based on user input membrane module information and wastewater design flow and characteristics. This Excel spreadsheet, as well as others for wastewater treatment process design calculations, is available in either U.S. or S.I. units for a very reasonable price in our spreadsheet store.
