4.6.5.1 Capital Costs
4.6.5.2 Operating Costs


4.6.5.1 Capital Costs

The PPS1 and PPS2 are sold for $800 and $460, respectively. The capacity of these units is not documented, so no attempt has been made in this report to show capital costs over a range of removal capacities. The manufacturer suggests that the PPS2 is applicable to tank volumes of 700 gallons or less and the PPS1 should be used for higher volumes, up to approximately 3,000 gal. (ref. Hard Chrome Plating Consultants, Inc. file)

The capital costs for the Artec polyfluorocarbon membrane technology ranges from approximately $10,000 to $30,000 for standard units with larger custom units available.

4.6.5.2 Operating Costs

Operating costs for the Artec polyfluorocarbon membrane technology are estimated by the manufacturer to range from $5 to $27 per pound of iron removed, depending on the level of bath contamination.

Respondents to the Users Survey reported that O&M labor requirements for the porous pot (PPS1 and PPS2) range from 26 hr/yr to 260 hr/yr and that non-labor costs range from $100/yr to $500 (excluding anolyte disposal costs).

Selected Users Survey cost data for the ion transfer technology is presented in Exhibit 4-25.
