[QUOTE="Chad Gardner, post: 334719, member: 20677"] I have been working on recovery of IPA after seeing how much I was spending on it monthly. I have come up with a simple filtration system that can be made for $50-150, depending on how much IPA you’re filtering. Bigger tank = more filters = more costs. Been using the same IPA for months now and took a sample to a local university chemistry professor for analysis and it came back 97%+ IPA and the original 99.99% bottle tested 99.111%. Only problem is it’s slow. Takes about a week for 4 gallons to be cleaned. Does anyone think there is a market for simple IPA recovery at such a slow rate? If so, what size would be ideal? 1-2 gallons = 1 filter and tanks for about $50. Above that and you need 2-3 filters. The filters are good for 10k gallons of water, so far they have done about 80 gallons of IPA and are doing great. And you get back about 91-93% of what you put in, so you’re losing some but what you get back is as good as a fresh bottle. Is the rate just too slow? I’m toying with pressurizing the tank to speed it up, but that will increase costs. Thoughts? Waste of time? Already been done? Not needed? [/QUOTE]
