Small WWTP Configuration

Extends from Modelica.Icons.Example.

Information

This fictitious plant provides an ASM3 example model with a small number of equations.
It consists of one denitrification and 2 nitrification tanks and a settler.

Change into the directory ../ASM3 and translate the model.
Before simulating the model load initial values from the script file small_asm3.mos
that is provided besides the model.
A 14 days dynamic influent data file is provided. So you may simulate up to 14 days.
But start with 1 day as it may take some time for simulation.
After simulation you may have a look at internal concentrations but most interesting
are the relevant concentrations at the effluent of a plant which can be viewed via the 
sensors at the effluent of the secondary clarifier.
