Alkaline Cleaner Recycling/Ceramic Membranes

I'm working on a project to verify the benefits of metal finishing pollution prevention technologies, and I need some feedback on the expected life of ceramic crossflow membranes used with backpulse in recycling alkaline cleaner baths. The membrane manufacturers claim 10+ years, but have no trustworthy data in hand.

Jim,

I would suggest that you contact Tom Weaver from DTW Systems. Tom has the original patents on the use of ceramic on alkaline cleaners, and has probably forgotten more than the current vendors ever knew, past & present.

For alkaline cleaner bath's you might consider using polypropylene membranes. They're cheaper and last longer in an alkaline environment.
