In addition, the new multi-tabbed graphical interface of GPS-X Version 6 made tracking each interunit's process performance a breeze. This helps establish the new Mantis2 biological model as one of the premier "Super Models" in the wastewater process modeling industry. 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. Two intensive sampling programs were carried out to render dynamic calibration and validation databases. The process included primary treatment, high purity oxygen activated sludge, secondary clarification, thickening, anaerobic digestion, dewatering, and advanced side-stream treatment. "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.
Successful Calibration and Application of the Mantis2 Biological Model at a Full-scale Wastewater Treatment Plant This is a tool I cannot imagine being without. 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. 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. Everyone could see and understand how the biological reactor was deficient in oxygen-generation capacity. Immediately, everyone, knowledgeable in wastewater treatment or not, could understand and relate to how increasing the COD loading consumed oxygen 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.Īll that changed when I ran several GPS-X simulations as part of a presentation. 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. Some of those streams included crude tank water draws, alky unit wastewater, desalter brine, and wastewater stripper effluent.
"I recently spent 30 days analyzing numerous waste streams that enter a refinery wastewater treatment plant.
