Innovative Tools:

GPS-XTM contains a suite of sophisticated tools allowing you to create advanced plant layouts, run interactive simulations, and perform in-depth analysis on model results.

Process Controllers:
GPS-X includes a set of robust process controllers to create treatment plant layouts with complex process control schemes.

Various Types of Controllers

1. PID Controller
2. ON/OFF Controller
3. Timer Controller
4. Flow Timer Controller
5. Scheduler Controller

In addition to stand-alone controllers, many unit processes have built-in PID controllers for easy setup (e.g. DO controller in aeration tank, RAS and WAS controller in secondary clarifier etc.).

A collection of standalone PID, PID feedforward, ON/OFF, Timer and Scheduler controllers allow you to build complex control systems like cascade ammonia based DO control, flow sequencing control in plant etc.

Analyzer:

The Analyzer module allows you to automatically perform steady-state or dynamic sensitivity analyses on model parameters, which will save you a significant amount of time and effort.

Monte Carlo Analysis:

Monte Carlo analysis in GPS-XTM allows users to generate probabilistic distribution of model outputs based on inputs with predefined probabilistic distribution. Both steady-state or dynamic Monte Carlo simulations can be performed in GPS-XTM. This analysis can be used to assess the effect of uncertainty in model parameter and or model input on the model outputs.

A robust Monte Carlo Analysis Tool allows users to evaluate plant performance when not all of the model inputs are well-known. Users can now run simulations using a typical distribution of values, rather than being forced to choose a single value, and observe a range of model outputs.

For example, users can predict a range of effluent ammonia concentrations given the typical range of nitrifier growth rates, even though the true actual growth rate isn’t known.

The Monte Carlo Analysis Tool is a valuable addition to the GPS-XTM toolkit, and provides users with a way to bring the uncertainty of real life into their models.
