"Over the past 4 years, we have been working with Hydromantis on the development of a hybrid MABR (membrane-aerated biofilm reactor) using the GPS-X platform. Hydromantis developed a process model which we used to guide our research and interpret piloting results. Modelling allowed us to shrink the development schedule and reduce the cost of experimental work. GPS-X now contains a full-fledged MABR model validated with field data. We are extremely pleased with the support that we got from Hydromantis in this project."

"I recently spent 30 days analyzing numerous waste streams that enter a refinery wastewater treatment plant. Some of those streams included crude tank water draws, alky unit wastewater, desalter brine, and wastewater stripper effluent. Oxygen uptake rate testing was conducted repeatedly to determine the time to endogenous respiration, the oxygen consumption associated with the individual waste streams, and the total oxygen consumption in the biological reactor. Along the way, numerous data tables and graphs were being generated and communicating the wealth of information very quickly became a difficult task.

All that changed when I ran several GPS-X simulations as part of a presentation. Immediately, everyone, knowledgeable in wastewater treatment or not, could understand and relate to how increasing the COD loading consumed oxygen in the biological reactor. Everyone could see and understand how the biological reactor was deficient in oxygen-generation capacity. The GPS-X model was then used to show how much additional aeration input was going to be required to sustain a dissolved oxygen concentration ≥ 2.0 mg/L, evaluating both horsepower requirements and pounds of air per day.

The mountains of laboriously collected and compiled data had failed to communicate, to "tell a story." The simulations and the different scenarios modeled using GPS-X succeeded where no amount of data could. This is a tool I cannot imagine being without. Thank you!!"

Successful Calibration and Application of the Mantis2 Biological Model at a Full-scale Wastewater Treatment Plant

"We developed a whole-plant process model for a large treatment plant in Pennsylvania with the new Mantis2 biological model on the GPS-X platform. The process included primary treatment, high purity oxygen activated sludge, secondary clarification, thickening, anaerobic digestion, dewatering, and advanced side-stream treatment. Two intensive sampling programs were carried out to render dynamic calibration and validation databases. It was clear that the new and more detailed influent characterization framework of the Mantis2 model coupled with the extensive array of dynamic state variables and process rate equations proved to represent both aerobic and anaerobic treatment performance extremely well. This helps establish the new Mantis2 biological model as one of the premier "Super Models" in the wastewater process modeling industry.

In addition, the new multi-tabbed graphical interface of GPS-X Version 6 made tracking each interunit's process performance a breeze. Over 20 ready-made process unit summary tabs and 40 dynamic graphs were created in a matter of minutes, while the excel-based reporting feature made simulation scenario documentation a snap."

"GPS-X 6.1 is the best tool to model complex biochemical systems to confirm or enhance my intuition and gain process insight which might not have been readily obvious.  It offers intuitive interfaces and an unmatched level of sophistication that reinforces my experience and has made me a better process analyst and designer."

"I just wanted to let you have some feedback on my use of GPS-X 6.1.  Overall, I’m extremely pleased with the mantis2 biological model.  It’s been very easy to calibrate, particularly using the influent advisor.  One of the features I like best is the standard report format in Excel.  The ability to generate separate tabs for each graph and process is great – this is vastly superior to the Word output reports used by competing products."

"GPS-X is one of the most powerful tools available in the marketplace and the only one that could accommodate our need for customized interfaces.  We have simulated our two regional wastewater treatment facilities and one sub-regional facility with GPS-X.  Both the software and the expertise from Hydromantis have offered tremendous help with our planning, process design, and plant operations."

"I have been a Toxchem™ user since 2001, beginning with version 3 and recently graduating to version 4.  My chemical manufacturing facility has an onsite wastewater treatment plant, and Toxchem™ gives me all the modeling power I need for our environmental reporting obligations.

Toxchem version 4 enables me to perform modeling tasks efficiently and effectively, including evaluation of the data and results reporting. Additionally, the Hydromantis technical support staff was very helpful in making the transition from version 3 to 4 a smooth one.

Features in this version will allow our facility to evaluate anticipated process changes and their potential effect on our water discharge permit limits, giving us time to implement revised compliance strategies."
