Fresh Look and Feel

The entire GPS-XTM software interface has been reconfigured with a more modern look and feel. The look is brighter with crisp, clean lines and a more consistent colour scheme.

We've been around since the 80s, but we don't need to look like it.

Button Icons

Menus/Buttons

Most of the menus and buttons are still found in the same location as previous versions of GPS-XTM, however the button icons have been updated with a fresh look.

Scenarios

Another improvement involves the scenario menu. The current scenario is now displayed in the lower left-hand corner of the screen (just below the Start button).

This provides a better method to see scenarios with long names and to keep track of which scenario is being edited.

Scenario Identification

Model Additions/Improvements

High Purity Oxygen

Updated Closed-Basin High-Purity Oxygen (HPO)

This model simulates the feed of high-purity oxygen into the covered headspaces of the activated sludge tanks in series. The headspaces allow for the gas to move downstream and eventually be vented from the final headspace. The model predicts the gas transfer of O2, CH4, H2 and N2 between the headspace and the liquid (the transfer of N2O is modelled in the Mantis3 model as well).

Updated Chemical Dosage Model

A newly updated and expanded chemical dosage model has been created for the "In-line Chemical Dosage" object. The dosage is now specified as the mass of the total chemical, not just the metal ion as in previous versions of GPS-X.

Chemical Dosage Model

The list of available chemicals has been expanded. It now includes:

  • Aluminum sulphate (Al2(SO4)3·18H20)
  • Polyaluminum Chloride (PAC) (Al2(OH)nCL(6-n)
  • Sodium Aluminate (NaAlO2)
  • Ferric Chloride (FeCl3)
  • Ferris Sulphate (Fe2(SO4)3·9H20)
Composite Sampler

New Composite Sampler Object

You can link the composite sampler model to a specific stream label in the layout. The sampler will then create a composite sample from the continuous stream of model output.

Updated Sourcing Features

Sourcing Improvement

The sourcing feature allows you to link units together, so that they share a common set of biological and/or settling parameters.

The method to specify the sourcing has been improved and simplified, and new symbols have been added to the drawing board to differentiate between the parent and child.

Improved Management of Input/Output Tabs

Input/Output Tab Management

If you create many controllers and/or graph tabs, after a certain point the tab bar will change from displaying multiple rows to displaying a single scrolling row.

In addition, a drop-down menu has been added to allow quick access to the different tabs.

No More Hardware Dongles!

No Hardware Keys

You have spoken and we have listened! Over the years, the use of hardware keys has been a huge hassle for you and we are now pleased to announce that this latest release uses a dongle-less licensing system. You will not be required to insert a USB dongle key as with previous versions of GPS-X. Network licensing continues to be supported, and users can still have multiple versions of GPS-X on the same computer (the previous versions will still require the USB dongle).

+ so much more!

  • Updated SRT definition and control features
  • Improved autoscaling of time-series and bar graphs
  • Improved setup menu for the scale of time-series and bar graphs when autoscale is not being used
  • Detailed instructions for some of the more complex features (SRT definition, scenario configuration, etc.) are now shown directly on the menu
  • Options for copying-and-pasting cryptic variable information
  • Ability to easily hide the MLSS lines in the Sankey diagram if they are much thicker than the rest of the lines in the layout
  • Many small fixes and adjustments to improve solver performance, model predictions, and data exportation performance
