Here's another thought: at Med Device trade shows they give out all
sorts of gadgets used for IVs and the like. Check valves, filters,
orifrices. I think I even saw a countercurrent filter. You can do
home-project or school-lab projects with stuff so cheap (if they can
afford to give it out). The stuff is plastic, small and disposable.
Try devicelink.com as a ****tal. Usually it has the added advantage
that it's clear, hence visualisable. But it uses the same principles
as large scale chemical engineering.
Besides, the trend is that in the USA we will do the small-scale
high-value-added specialty processing and the commodity unspecialised
low-value-added mega processing will move to third world countries.
