Software Products GPS-X: Dynamic simulation of WWTP’s General Purposes Simulator for eXpert

Modeling Advantages Cheaper than building/modifying the real system - Try several different options and see what works best Can be easier than carrying out test on existing systems - Whip up a storm instantaneously - Take processes off-line Fast results! - Don’t need to wait for 3 SRTs (weeks or months) to see results Consequence-Free! - Simulated plant failures are a lot less costly than real ones :-)

GPS-X Application Fields Calibrated GPS-X models can be used for: Engineering –Design, optimization, analysis –Advanced control design Plant operation –Operator training –Daily operational advice –Interface model with on-line instrumentation to update model parameters and provide more precise predictions Planning and Compliance

Bio-P Plant Ortho-phosphate Ammonia Nitrate Nutrient profile along length of staged bioreactor

Uncontrolled Case Controlled Case Internal recycle is constant Nitrate in Anoxic 2 wanders Internal recycle is manipulated to control nitrate Nitrate in Anoxic 2 is kept close to setpoint of 1 mg-N/L

Calibration Example: Diurnal Flow Final effluent SS, mg/L Time, days

Effluent Forecasting GPS-X predicts: the effects of biological growth solids separation conventional water quality parameters including: –BOD, COD, TKN, TSS, Ammonia, Nitrate/Nitrite, and Soluble Phosphorus Quality of output from a model depends on: quantity and quality of input data available types of models utilized

GPS-X Advanced Features Operating Cost Models Dynamic Operating Cost Models are available for: Aeration energy cost Pumping energy cost Chemical dosage cost Sludge disposal cost (hauling, incineration, etc.) Miscellaneous energy cost (from rakes, gates etc.)

GPS-X Advanced Features Influent Advisor Influent Advisor modules assist in characterization of influents

GPS-X Advanced Features Dynamic Data Exchange (DDE) The possibilities for alternative interfaces for GPS-X are endless

Example of Customized Alternative Interface for GPS-X Clickable picture Data input Customizable output such as specific tables and/or graphs Excel worksheet functionality Layout can include customizable space for logo and/or other information Simulation progress Simulation control buttons Output choices

GPS-X Advanced Features Sensitivity Analysis The GPS-X Analyzer automates the task of performing sensitivity analysis on model parameters

GPS-X Advanced Features Parameter Optimization Example

GPS-X Optimization: GPS-X can tell you the optimal amount of polymer to add Give GPS-X a goal –Minimize total costs GPS-X will tell you the answer –Optimal polymer dosage

GPS-X Advanced Features Industrial Pollutant Modeling 30 user defined components are available to be incorporated into GPS-X to track industry specific pollutants

GPS-X Advanced Features Dynamic Parameter Estimator (DPE) Most model parameters used in GPS-X dynamic models are kept constant over the entire calibration period to simplify the modeling process A more rigorous approach would be vary the specific parameter(s) over the simulation period using the Dynamic Parameter Estimator (DPE)
