One of my biggest concern is the purification of the electrolytic solution. How is it normally done in industry? Should I use some special filter (eg. activated carbon filter) and pump the solution into a purification station? I really appreciate your comments on this issue.

Another concern is about the rectifier. How did you guys choose the rectifier while you are considering building up a production line? My application needs to have a high current density. concerning the surface area of the carbon fiber is large, the required current output from the rectifier as well. I checked some info. of rectifier on internet. It seems that the voltage range is kinda low but the current range is very high. How do they make that happen? Does that mean the loading resistance must be extremely low in order to get a high current output?

Thanks for your attention. I am looking forward to your help.
