Welcome to GPS-XTM Lite. This software is a free, simplified version of GPS-XTM which is a dynamic wastewater treatment plant simulator produced by Hydromantis Environmental Software Solutions, Inc.
This software can be used to complement the textbook:
Theory and Practice of Water and Wastewater Treatment, 2e, by RL Droste and RL Gehr, available from the publisher, John Wiley & Sons.
The GPS-XTM Lite version of the software allows users to become familiar with how to model simple activated sludge processes, and understand the relationships that exist between the physical, operational, stoichiometric, and kinetic parameters of the process models and simulator output.
If you are a professor at an accredited university or college, please contact us to enquire about an academic version of the fully featured version of GPS-X.
Intended Audience
Academic institutions looking to augment their teaching of wastewater treatment concepts incorporating process modelling. The software comes with several dedicated lessons suitable for undergraduate/graduate supplemental material.
People wishing to become more familiar with concepts related to wastewater treatment modelling
People curious about how GPS-XTM can be used to model wastewater treatment plants
Restrictions
As GPS-XTM Lite is a simplified version of GPS-XTM, it allows you to perform various activities, but there are several restrictions in place including:
-
Limited to only the ASM1 model
-
Limited number of unit processes with only one instance of each available unit process
-
Inability to load and run layouts produced in full version of GPS-XTM
-
Limitations on some model parameters including the wastewater influent composition, and the physical parameters of the suspended growth and secondary clarifier model objects
-
Deactivation of several advanced features in GPS-XTM including the Optimizer, Sensitivity Analysis, and Process Control tools
-
The duration of dynamic simulations must be less than 1-day
-
Inability to produce reports of simulation results
The complete version of GPS-XTM provides users with the most comprehensive suite of unit processes, comprehensive process models and advanced features to allow for advanced mathematical modeling, control, optimization and management of wastewater treatment plants.
