Where to Find a UASB Design Calculations Spreadsheet

To obtain a UASB Design Calculations Spreadsheet, click here to visit our spreadsheet store.  This Excel spreadsheet is intended for making design calculations for the upflow anaerobic sludge blanket wastewater treatment process. You can buy a convenient spreadsheet for making USAB design calculations  for a very reasonable price.  It is available in either U.S. units or S.I. units.  Read on for background information about upflow anaerobic sludge blanket wastewater treatment design calculations.

Background for a UASB Design Calculations Spreadsheet

The upflow anaerobic sludge blanket wastewater treatment process is typically used for treatment or pretreatment of wastewaters with a high BOD concentration.  The process has a sludge blanket in the reactor zone, through which the influent wastewater flows.  Also, the top part of the reactor includes a means for collecting the methane biogas generated by the anaerobic process.  A schematic flow diagram of the process is shown here:

 Example UASB Design Calculations Spreadsheet

An example UASB design calculations spreadsheet is partially shown in the image below.  This Excel spreadsheet can be used to calculate the required UASB reactor volume and dimensions, sludge production rate, methane production rate, and required alkalinity addition based on user input information on wastewater flow and characteristics, biokinetic parameters, methane stoichiometry parameters, and reactor configuration and design parameters.  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.
