MBBR processes in Wastewater Treatment Spreadsheet Bundles

MBBR wastewater treatment process design spreadsheets are included in all of the MBBR-MBR-SBR spreadsheet bundle mentioned above.  The MBBR wastewater treatment process is quite flexible.  It is used for domestic and industrial wastewater treatment and can be designed for BOD removal alone or in combination with nitrification or with nitrification and denitrification.  It is used as a single stage process or as a two-stage or three-stage process.

The diagram below shows the general configuration of a Pre-anoxic nitrification denitrification MBBR wastewater treatment process.  Denitrification can also be carried out in a Post-Anoxic nitrification denitrification process.

MBR Processes in Wastewater Treatment Spreadsheet Bundles

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.
