GPS-X What is GPS-X? Slideshow Modules Wastewater Process Libraries Technical Specifications Detailed Specifications						TECHNICAL SPECIFICATIONS Basic Simulator Features Steady state AND dynamic simulation software. Completely interactive, allowing fast feedback and analysis of results, saves time compared to using "batch" (run and observe) simulators. Built in unit conversion to non-SI units (e.g. US units). Flexible data input and graphical output features (graphs, data files, DDE, etc.). Communicates with spreadsheet programs (e.g. Microsoft Excel). All forms are populated with default values from scientific literature. Reads and uses real plant data as simulation inputs or for comparison to simulation results. Automatic process consistency check and warnings. Capable of supporting different languages. Y2K compliant. Advanced Simulator Features Customizable (user can change models and interface forms, can add new models). On-line automated real-time operation capability. Can be connected to SCADA systems. Automatic calibration, advanced sensor fault detection, process fault detection, automated forecasting available. Contains built-in routines for On-Off, P, PI, PID, and lead-lag feedforward control simulation. Built in PID controller tuning facility. Dynamically links to Matlab for design and simulation of advanced model based control systems. Unit Operations Influent Splitters, 2 to 5 streams Combiners, 2 to 5 streams Pumping Station (Wet Well) Equalization Tank Grit Chamber Activated Sludge Tanks (CSTR, Plug-flow tank, Dual inlet plug-flow tank) Sequencing Batch Reactor Trickling Filter Biological Aerated Filter Rotating Biological Contactor Deep Shaft Thickener Dewatering Primary Settlers (Circular and rectangular) Final Clarifiers (Circular and rectangular) Aerobic Digester Anaerobic Digester Sand Filter Disinfection Black Box (18 predefined transfer functions for empirical modeling, user customizable) Tools (Signal tracking and alarm, pH model, sampler, flow or time based composite samples, PID controller, feedforward-feedback controllers, on-off controller, multivariable controller, low-pass filter) Customize an interface and run your GPS-X simulations from programs such as Microsoft Excel.
