Performance analysis and optimization of an advanced pharmaceutical wastewater treatment plant through a visual basic software tool (PWWT.VB)

Abstract

A user-friendly, menu-driven simulation software tool has been developed for the first time to optimize and analyze the system performance of an advanced continuous membrane-integrated pharmaceutical wastewater treatment plant. The software allows pre-analysis and manipulation of input data which helps in optimization and shows the software performance visually on a graphical platform. Moreover, the software helps the user to "visualize" the effects of the operating parameters through its model-predicted output profiles. The software is based on a dynamic mathematical model, developed for a systematically integrated forward osmosis-nanofiltration process for removal of toxic organic compounds from pharmaceutical wastewater. The model-predicted values have been observed to corroborate well with the extensive experimental investigations which were found to be consistent under varying operating conditions like operating pressure, operating flow rate, and draw solute concentration. Low values of the relative error (RE = 0.09) and high values of Willmott-d-index (d will = 0.981) reflected a high degree of accuracy and reliability of the software. This software is likely to be a very efficient tool for system design or simulation of an advanced membrane-integrated treatment plant for hazardous wastewater.

Mathematical Simulation of Nanofiltration Process: State of Art Review

“…In particular, the considered model was used for describing the water treatment processes 9,55,[68][69][70][71][72][73] . On the other hand, the problem of treatment of hazardous effluent was also considered 62,65,66,74,75 . In several works, the authors restricted the theoretical investigation of the ions transport through the membrane 60,76 or the removal of salts 56,57,61,64,68,69,[77][78][79][80] .…”

“…The extended Nernst-Planck equation-based models were also applied in combination with other theoretical concepts such as the Poisson equation 84 , the concentration polarization models 59 , the method of economic analysis 62 and optimization 80 , as well as the computational fluid dynamics 19,59,84 . However, the combination of the extended Nernst-Planck with the Donnan equilibrium in one investigation was the most common practice 9,56,57,[59][60][61]64,65,[69][70][71][75][76][77][81][82][85][86][87] . This approach will be discussed in detail below.…”

“…Among the software, that was used in publications considered in this section, the application of COMSOL Multiphysics 59,84 , MATLAB 76,82 , and also the program-ming languages Visual Basic 68,75 and Python 72 should be noticed.…”
