Design and calculation of tanks in the wastewater treatment system

Designing a wastewater treatment system is the job for an environmental engineer. Calculating the many parameters and choosing the correct coefficient can be a very complicated task. However, the Nam Viet environmental engineering company has designed a quick spreadsheet to assist engineers and help customers with calculating the size and volume of wastewater treatment tanks.

How to use the wastewater treatment system design calculation table:

  • Click on the type of tank you would like to calculate
  • Enter the system parameters and select the appropriate coefficient
  • Press enter and the system will display the relevant results
