1. Longitudinal Section of a Broad Crested Weir with Free Flow overthe Weir
The flow over a broad crested weir is referred to as free flow if the depth of water flowing immediately downstream of the weir is lower than the weir crest (the top of the weir), as shown in Figure 1. The _broad crested weir calculations spreadsheet_ being described here can calculate the flow rate over the weir for user specified values of the depth of flow upstream of the weir, y1, the length of the weir crest, L, (typically equal to the width of channel in which the broad crested weir is placed), and the value to be used for the weir coefficient, C. The equation used for this calculations is:A
similar calculation can be made for submerged flow over the broad crested weir, in which the depth of flow immediately downstream of the weir is greater than the height of the weir. Submerged flow over a broad crested weir is shown in Figure 2 below.Also
the required upstream head above the weir crest can be calculated for a given flow rate over the weir for either free flow over the weir orsubmerged flow

Excel spreadsheet is intended for making design calculations for either pre-anoxic or post-anoxic denitrification in a sequencing batch reactor. 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.

It is available in either U.S. units or S.I. units. Read on for background information about_ dissolved air flotation design calculations_. BACKGROUND FOR DISSOLVED AIR FLOTATION DESIGN CALCULATIONS Dissolved air flotation is an alternative to clarification for removal of fine suspended mater from a water or wastewater stream. It is especially good for fine suspended matter that doesn’t settle out well with regular clarification. The air-solids ratio, A/S, is typically calculated with the following equation:Where:
sa is the air solubility, f is an efficiency factor, P is the recycle pressure, R is the recycle flow rate, Sa is the influent suspended solids concentration, and Q is the influent flow rate. The required DAF area can be calculated based on a design value for DAF hydraulic loading rate or based on a design value for DAF solids loading rate. EXAMPLE DISSOLVED AIR FLOTATION DESIGN CALCULATIONS SPREADSHEET An example _dissolved air flotation design calculations spreadsheet _is partially shown in the image below. This Excel spreadsheet can be used to calculate A/S, the needed air to solids ratio, and the required DAF area based on user input information on influent design flow and characteristics.

Excel spreadsheet is intended for making membrane bioreactor process design calculations. YOU CAN BUY A CONVENIENT MEMBRANE BIOREACTOR WASTEWATER TREATMENT CALCULATIONS SPREADSHEET FOR A VERY REASONABLE PRICE. This spreadsheet . It is available in either U.S. units or S.I. units. Read on for information about a membrane bioreactor wastewater treatment calculations spreadsheet. BACKGROUND FOR MEMBRANE BIOREACTOR WASTEWATER TREATMENT CALCULATIONSSPREADSHEET
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. EXAMPLE MEMBRANE BIOREACTOR WASTEWATER TREATMENT CALCULATIONSSPREADSHEET
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.

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).
