001120 |
2.0.0 |
New version (2.0.0) of the simulator: The sedimentation unit has been
upgraded to a layer model with 10 vertical layers. A supervisory DO controller
is now implemented The treatment results in terms of total N removal,
BOD removal etc.are now presented in a comprehensive way. |

1.0.1 |
Changed (fastened) the sampling interval for oxygen PID controller.
Changed to volume dependent oxygen transfer function, KLa*V0/V
where V0 is the default volume. |
980327 |
1.0.0 |
New demo version for the simulator!!!!!! |
980225 |
0.1.5 |
Added temperature dependent process constants in the simulators |
980223 |
0.1.4 |
Added possibility to run simulations with time varying flows
in the simulators built for Uppsala and Västerås wwt plants |
980212 |
0.1.3 |
Updated versions for the waste water treatment plants in Uppsala and
Västerås completed. |
971212 |
0.1.2 |
Nodified data transfer between different program parts (bug fixed)
changes in process parameters now affect all zones (bug fixed) added possibility
to plot air flow rates and carbon flow rates in all basins. |
970903 |
0.1.1 |
Added LQG regulator for external carbon source, added units of
all flows in the process image, corrected deafault values of bar diagrams |
970825 |
0.1.0 |
Added possibility to click on a zone (or the settler) in the
processimage to shade the corresponding bars in the bar diagrams. This
makes it a lot easier to read off the diagrams. We thank Stefan Mårtensson
for suggesting this feature. |
970822 |
0.0.2 |
Added value checking for all input data, added units to the scrolling
graph, changed text in choice bars to lower case letters |
970821 |
0.0.1 |
Changed colours of pump symbols (green means active pump, yellow
inactive), changed value of COD for carbon source to 1200000 mg/l (methanol),
changed text colours in the interface |
