4.4.5.1 Capital Costs

A diagram showing the equipment costs for the application of ion exchange to chromic acid baths is presented in Exhibit 4-10. Installed costs for these systems are approximately 10 to 30 percent higher than basic equipment costs.


4.4.5.2 Operating Costs

Operating cost data provided by respondents to the Users Survey are presented in Exhibit 4-11. The annual costs and savings for the respondents are shown graphically in Exhibit 4-12, which also expresses capital costs in terms of 1993 dollars. This graphic indicates that a relatively rapid capital payback is possible with this technology (see bar graph for PS 049 and PS 191).
