That's kind of what I was thinking, a separate unit to filter the alcohol between washes as required. I've never heard of a chemical R/O before, could you elaborate? If it's anything like the water ro with a 4 to 1 waste ratio it would be much good. I can't invest in something that will only recover a small portion of the alcohol, it has to be the majority if not all.
Also the sediment won't be beneficial, the parts are actually pretty clean when they go in but there will be traces of grit from the sandblaster and oil from heat treating as well as whatever chemicals are used in the powder coating or plating processes. If any particles remain on the surface the gauging process could fail which is not good.
