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.

Where to Find a Sequencing Batch Reactor Design Calculation Spreadsheet

To obtain a Sequencing Batch Reactor Design Calculation excel spreadsheet, click here to visit our spreadsheet store. For use in wastewater treatment design calculations, you can buy a convenient sequencing batch reactor design calculation excel spreadsheet for a very reasonable price? This spreadsheet will make calculations for BOD removal, nitrification, denitrification, and biological phosphorus removal for given information about wastewater flow rate and characteristics, in either U.S. or S.I. units. Read on for information about Excel spreadsheets that can be used for SBR design calculations.

Sequencing Batch Reactor Design Calculation Background

A typical activated sludge wastewater treatment process operates as a continuous flow process, with incoming wastewater flow coming into a primary clarifier and treated effluent continuously coming off from the secondary clarifier. A sequencing batch reactor wastewater treatment system, on the other hand, operates as a batch system. Two or more tanks are required. While one tank is receiving influent wastewater (the “fill” part of the cycle), another tank is undergoing aeration (the “react” part of the cycle), settling (the “settle” part of the cycle) and decanting of treated effluent (the “decant” part of the cycle). This is illustrated in the diagram below.

Sequencing Batch Reactor Design Calculation Applications

A sequencing batch reactor wastewater treatment system has a great deal of flexibility. It can be used for traditional BOD removal and nitrification using the four cycle components shown above. In that case there may be aeration for at least part of the fill cycle. If denitrification is to be accomplished also, then there should be no aeration during the fill cycle. If the SBR wastewater treatment system is to be designed for biological phosphorus removal as well, then an anaerobic react period is needed after the fill portion of the cycle, and an anoxic react is needed after the aerobic react part of the cycle, as shown in the diagram below.

Example Sequencing Batch Reactor Design Calculation Excel Spreadsheet

The Sequencing Batch Reactor Design Calculation excel spreadsheet partially shown in the image below can be used to make a variety of design calculations for an SBR wastewater treatment system. Based on input information about the wastewater flow rate and characteristics, as well as the treatment objectives, the spreadsheet leads the user through calculations for deciding on times for each part of the SBR cycle, tank number and size, and checks on the adequacy of the design. This Excel spreadsheet, as well as others for wastewater treatment calculations, is available in either U.S. or S.I. units for a very reasonable price in our spreadsheet store.
