We're constantly striving to improve GPS-X and stay on the leading edge of the wastewater industry.
Click the version numbers below to see what was added or improved in that release.
Bug fix for inactivation of controllers in a scenario
Add Japanese and Korean language translations
Update to address memory management issue on some newer computers
Adjustment of Monte Carlo sampling methodology
Updated default parameter settings for Mantis3 and PW2 models, to align with Mantis2 defaults
Assorted menu text changes/fixes for typos and improved clarity
New Interface Features
New model output benchmarking, quickly identifying parameters out of typical ranges New Data Filtering and Outlier Logging for all input time series Scenarios can now include changes to input controllers New Simulation Log for keeping track of simulations and viewing warnings
Weekly Scheduler Controller – easily set a weekly schedule for process operation (e.g. centrifuge only runs 8am-4pm on weekdays)
Conditional Controller – set parameter values based on other parameter values in the model (e.g. bypass flow if influent is greater than a certain amount)
Discrete Event Scheduler – create discrete parameter changes to happen a scheduled or random time in the future
Estimation of Oxidation/Reduction potential (ORP) in all tanks and streams Australian Water Balance Model (AWBM) – a sophisticated runoff model that simulates stormwater flow based on rainfall Delayed Pipe Model – simulate the effects of a delay in flow between unit processes Updated Chemical Dosage Model – new features to allow dosage by chemical volume (e.g. L/min, gal/d, etc.) Updated Calibration of Various Models – to reflect advances in wastewater technology, through our experiences applying GPS-X

Plug-Flow Tank volume correction
If you chose "Individual Volumes" to define the tank volumes in your model, then the correct volume was not being set in the model. This was corrected and it is confirmed that this was a bug that got introduced in version 8.0 due to a model update.
This fix will affect your calculation only if you chose "Individual Volume" method in any of the Plug-Flow Tank, Dual Inlet Plug-Flow Tank, Plug-Flow Tank with Aeration header, Closed Basin HPO, membrane aerated bioreactor.
Fixed an issue where switching a process object's model would sometimes lead to a layout saving error.
Added the ability to "show tooltips" and "copy cryptic to clipboard" on new table format dialogs.
Corrected the Treated Water object's quick panel display.
Fixed the incorrect units on "Solid Loading Rate" display variables in clarifiers.
