You can buy your choice of several different convenient wastewater treatment excel spreadsheet bundles for a very reasonable prices. These Excel spreadsheet bundles include process design calculations for MBBR wastewater treatment processes, MBR wastewater treatment processed, SBR wastewater treatment processes, activated sludge design calculations, and several other wastewater treatment processes. These Excel spreadsheets are available in either U.S. units or S.I. units. Read on for more information about these wastewater treatment spreadsheet bundles.
Available Wastewater Treatment Spreadsheet Bundles
The wastewater treatment spreadsheet bundles available from the EngineeringExcelTemplates.com DOWNLOADS page are “Biological-Secondary Wastewater Treatment Bundle“, “Nitrification and Denitrification Bundle“, “Wastewater Treatment Complete Spreadsheet Bundle“. and “MBBR-MBR-SBR Spreadsheet Bundle”.
Descriptions of these spreadsheet bundles and descriptions of the spreadsheets included in each of them are available through the links in the previous paragraph.
MBBR processes in Wastewater Treatment Spreadsheet Bundles
MBBR wastewater treatment process design spreadsheets are included in all of the wastewater treatment spreadsheet bundles described 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.
