Pollution Prevention and Control Technologies for Plating Operations
Section 1 - Overview of Project Results
1.1 Description of Project
1.1.6 Description of the Vendors Survey
The Vendors Survey was conducted to supplement the data from the Users Survey. Whereas the focus of the Users Survey was on determining the performance and operating costs for technologies, the focus of the Vendors Survey was on identifying the types, capital costs and design features of commercially available equipment. Also, companies offering off-site metals recycling services were surveyed. Twelve specific questionnaires were prepared to solicit information on the following topics:
Ion Exchange
Electrowinning
Electrodialysis
Diffusion Dialysis
Membrane Electrolysis
Atmospheric Evaporators
Vacuum Evaporators
Reverse Osmosis
Ultrafiltration/Microfiltration
Acid Sorption (acid retardation)
End-of-Pipe Treatment
Off-Site Metals RecyclingEach of the technology survey forms requested respondents to provide a specific list of applications for their equipment (e.g., recovery of nickel from rinse water), the number of units sold for each application, available equipment sizes or capacities, materials of construction, optional equipment, expected equipment life-span and equipment prices.
Thirty-five manufacturers/vendors of these pollution prevention and control technologies and services completed survey forms or provided equivalent information. These companies are listed in Exhibit 1-3.
