A computer model package 'ASPAIR' was developed in the project to describe the air stripping process along with processes for controlling the air emissions. The package is integrated with a commercially available process simulator called ASPEN to design and cost an air stripper and emission control system for specific applications. The applicability of the ASPAIR model package was demonstrated through several case studies which highlighted the effect of important parameters such as, Henry's Law constant, gas to liquid ratio, VOC removal efficiency, and wastewater throughput. The results of these case studies are presented in a graphical form to allow quick 'short-cut' estimates of the performance and cost of an air stripper and associated air emissions control units. Two figures are provided in the manual that illustrate the capital and annualized costs as a function of wastewater flow rate and Henry's Law constant for a desired VOC removal efficiency of 90%. Two additional figures are provided that illustrate a similar cost correlation for a desired VOC removal rate efficiency of 99%. The manual also provides capital and annualized costs graphs for catalytic oxidation and carbon adsorption units used to control the emissions from air strippers.
