Thanks for pointing this out, Robert! We are aware of this study, and were in contact with the authors at Santa Clara last year regarding the methods they used. It is an interesting but quite limited study, and what we are proposing in this project moves well beyond it.

Yes - we place bottles like this containing different doses of char and mixtures of trace chemical contaminants on tumblers and shake tables to agitate for ~ 2 weeks.

We use a set of scaling equations based upon mass transport models to define the small column parameters - the dimensions of the column, the flow rate, the mass and particle size of char, etc. These models allow us to maintain similarity between the small-scale lab column and the full-scale treatment system. But our operational run-time scales way down, so that we can simulate 1 or a few years' full-scale operation in 2-3 weeks, and using much smaller quantities of reagents and water. Good question John! I can nerd-out on this stuff super hard, so ask as many questions as you like.....

Thanks for your support Xavier! You can find some how-to materials at http://www.aqsolutions.org - let me know if you have questions. There are many PunPun people, and some folks around Mae Sot, too, who have experience with these systems and could potentially help you out. Let me know if you'd like me to put you in touch.

Thanks Lach! I think some people at University of Vermont tried something like that - they used mesh bags of char suspended in streams near dairies, to try to protect water quality in Lake Champlain. I will check in with them and see how it worked....
