Pollution Prevention and Control Technologies for Plating Operations
Section 4 - Chemical Solution Maintenance
4.7 MEMBRANE ELECTROLYSIS
4.7.7 Operational and Maintenance Experience
The following summarizes the respondentís O&M experiences and provides operating labor information.
- Two shops provided operating labor data. For these shops, the average number of annual operating hours per membrane electrolysis unit were: 200 hrs/yr (assumes 250 hrs/yr for each of the two units operated by PS 275). The following is a breakdown of the responses for skill requirements (based on data from PS 006, PS 052 and PS 275):
Environmental Engineer: 0 Process/Chemical Engineer:0 Chemist: 1 Consultant: 0 Plumber/Pipe Fitter: 0 Electrician: 0 Vendor: 0 Senior-Level Plater: 1 Junior Level Plater: 0 Trained Technician: 2 Common Labor: 0 Other: 0
- Reported O&M problems for this technology include: (1) occasional clogging of pipes (PS 052); short life span of membrane and anodes (PS 006); and (3) very difficult to clean out collected residuals from unit.
- Ionsep reported the following expected life spans of system components: membrane >12 mth, anode 12 to 36 mth, and cathode >60 mth.
