WHERE TO FIND MBBR MBR SBR SPREADSHEETS To obtain _MBBR MBR SBR spreadsheets_, click here to visit ourspreadsheet store
. YOU
CAN BUY YOUR CHOICE OF SEVERAL DIFFERENT MBBR MBR SBR SPREADSHEETS AS A CONVENIENT MBBR-MBR-SBR SPREADSHEET BUNDLE OR EXCEL SPREADSHEETS FOR WASTEWATER TREATMENT DESIGN FOR MBBR WASTEWATER TREATMENT, MBR WASTEWATER TREATMENT OR SBR WASTEWATER TREATMENT FOR VERY REASONABLE PRICES. This Excel spreadsheet bundle include process design calculations for MBBR wastewater treatment processes, MBR wastewater treatment processed, SBR wastewater treatment processes. These Excel spreadsheets are available in either U.S. units or S.I. units. Read on for more information about _MBBR MBR SBR Spreadsheets_. 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. Figure 1. MBBR Wastewater Treatment Flow Diagram for Pre-AnoxicDeniitrification
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.Figure
2. MBR Wastewater Treatment Flow Diagram for BOD Removal andNitrification
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.REFERENCES:

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. Figure 1. MBBR Wastewater Treatment Flow Diagram for Pre-AnoxicDeniitrification
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.Figure

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.REFERENCES:

YOU CAN BUY A CONVENIENT SBR DENITRIFICATION CALCULATIONS SPREADSHEET FOR A VERY REASONABLE PRICE. It is available in either U.S. units or S.I. units. Read on for background information about_ sequencing batch reactor denitrification process design calculations_. BACKGROUND FOR AN SBR DENITRIFICATION CALCULATIONS SPREADSHEET The sequencing batch reactor is a batch type, fill and draw alternative to the continuous flow activated sludge process for biological wastewater treatment, including BOD removal, nitrification and denitrification. The typical components of a sequencing batch reactor operating cycle for BOD removal and nitrification are shown inthe diagram below.
At
least two tanks are typically used. In that case, the length of the fill period would be equal to the sum of the times for the react, settle and decant periods. Thus one tank would be filling while the other tank was going through the react, settle and decant periods and then the roles would be reversed. In order to achieve denitrification, an anoxic period must be added. A typical sequencing batch reactor cycle for a post-anoxic denitrification process is shown in the figure below. A mixed anoxic react period is included after the aerobic react period.For
a pre-anoxic denitrification SBR process, some or all of the fill period would be anoxic and there would be no anoxic react period after the aerobic react period. EXAMPLE SBR DENITRIFICATION CALCULATIONS SPREADSHEET An example _SBR denitrification calculations spreadsheet _is partially shown in the image below. This Excel spreadsheet can be used to set the times for the different parts of the SBR operating cycle, calculate the required tank size and check on the adequacy for nitrification and for denitrification. 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.

WHERE TO FIND AN API 570 PIPING INSPECTION CALCULATIONS SPREADSHEET To obtain an _API 570 Piping Inspection Calculations spreadsheet_, click here to visit our spreadsheet store. This
Excel spreadsheet is intended for making piping inspection calculations from API 570 and API 574.. YOU CAN BUY A CONVENIENT API 570 PIPING INSPECTION CALCULATIONS SPREADSHEET FOR A VERY REASONABLE PRICE. This spreadsheet calculates required minimum pipe wall thickness, long term corrosion rate, short term corrosion rate, remaining life, and maximum allowable working pressure (MAWP). It is available in either U.S. units or S.I. units. Read on for information about using an API 570 piping inspection calculationsspreadsheet.
FORMULAS FOR API 570 PIPING INSPECTION CALCULATIONS SPREADSHEET The required minimum wall thickness for piping being inspected must be the greater of the calculated pressure design wall thickness and the structural minimum wall thickness. The pressure design wall thickness is sometimes calculated with the Barlow formula and sometimes it is calculated with the ASME B31.3 formula. Both areshown below.
In
the Barlow formula and the ASME B31.3 formula, P is the design fluid pressure in psig, D is the pipe O.D. in inches, S is the allowable unit stress of the pipe material in psi, E is a longitudinal quality factor, and Y is a coefficient that is a function of the pipe material and the operating temperature. The structural minimum wall thickness is available in API 574 Table 6 for some pipe materials. The required minimum pipe wall thickness is the greater of the calculated pressure design wall thickness and the structural minimum wall thickness. The long term corrosion rate and short term corrosion rate are calculated from values for the current measured pipe wall thickness, a previous pipe wall thickness or the initial pipe wall thickness and the time between the two. The remaining life of the pipe is calculated as the difference between the current measured pipe wall thickness minus the required minimum pipe wall thickness divided bythe corrosion rate.
The maximum allowable working pressure for a pipe is calculated fromthe formula:
MAWP = 2SET/D
In this formula, S, E, and D are as defined above and t is the measured pipe wall thickness in inches. EXAMPLE API 570 PIPING INSPECTION CALCULATIONS SPREADSHEET An example _API Piping Inspection Calculatons spreadsheet _is partially shown in the image below. This Excel spreadsheet can be used to calculate the required minimum pipe wall thickness, corrosion rate, remaining life, and maximum allowable working pressure (MAWP).
