Pollution Prevention and Control Technologies for Plating Operations
Section 4 - Chemical Solution Maintenance
4.4 ION EXCHANGE
4.4.5 Costs
4.4.5.1 Capital Costs
4.4.5.2 Operating 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.
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).
