April 7, 2016 – CyboSoft released Real-Time pH Process Modeling and Control Simulation Software family to help engineers learn how a pH process behaves, and how to effectively control this extremely nonlinear process to comply with EPA wastewater discharge codes and save chemical reagent.
The software is built in National Instruments' LabVIEW platform and includes: (1) pH process diagram, (2) a strong-acid-strong-base pH model, (3) a weak-acid-strong-base pH model, (4) a strong-acid-weak-base pH model, (5) a weak-acid-weak-base pH model, (6) MFA control simulation for the 4 pH processes using an MFA pH controller, (7) PID control simulation for the 4 pH processes, (8) On-Off control simulation for the 4 pH processes, (9) graphical interface with control faceplates and real-time trends, (10) LabVIEW diagrams, and (11) pH process model description, MFA controllers used, and recommended control strategy.
The pH process models are delivered as VIs (virtual instruments) in LabVIEW. The user can design and test their pH control systems using the pH process models running in real-time. For instance, a pH process model can run in a PC with real-time interface to a popular pH controller on the market or to an existing pH controller in service. The control results can be compared with the MFA pH control results obtained in MFA control simulations. The user can then take the results, estimate the chemical reagent savings, and show the potential return-on-investment (ROI) when applying for budget to buy the proper pH controller or control software to improve pH control performance.
