EXPOPLAN – Software tools for the design of wastewater treatment facilities


Design software for the application of DWA Topic "Design of wastewater treatment plants in warm and cold climates"

In the BMBF-funded EXPOPLAN project, worldwide applicable software tools for the planning of wastewater treatment plants were developed. They are provided free of charge as a web application on the Internet and in new versions of the simulation software SIMBA# (from version 4.2).

The software tools are based on the DWA Topic T4/2016 "Design of wastewater treatment plants in warm and cold climate zones", which was published for the first time in 2016 and describes internationally applicable design approaches for wastewater treatment plants. In addition, calculations of costs and CO2 equivalents were implemented in the tools to evaluate the plants. The web-based EXPOPLAN planning tool is not only open to users, but also to developers of other process modules.

Access to the web application

Free login without registration (design data is only saved on the user's local computer):

No SIMBA# knowledge is required for the application. After the login a manual with further information about structure and background is available.

Process steps implemented

The currently integrated process modules of wastewater treatment are:

  • Mechanical pre-treatment
  • Activated sludge stage (activated sludge tank and secondary clarification)
  • Trickling filter
  • Anaerobic wastewater treatment as UASB reactor
  • Anaerobic, aerated and optional wastewater ponds
  • Sewage lifting station (inlet or intermediate lifting station)

Sludge streams arising in each stage are collected additively and fed into the sludge treatment as a mixture. Options for this are:

  • Mechanical sludge dewatering
  • Anaerobic sludge tratment (digestior)
  • Agricultural application
  • Solar sludge drying
  • Sludge mono-incineration
  • Sludge co-incineration
