Hi, TechNetters:
Does anybody know the present situation by using the ultra-filtration
system
to recycle the developer and the stripper which should be discarded after
aging
everyday.
Are there many users or only some users in the States to use UF in this
PCB or etching process?
Hope to get some ideas about the marketing or the users experience in
these alkali solution recycling.
It is said to save much fee for treating the waste solution and COD
problem.
Thanks
Chung J. Lee /Hsin-Sun
