I see now that the information I sought is on the turner biodiesel website.

Thanks for uploading the diagram of your system, Dorn. Where are the filters and what sizes are they?

That would be great! How many gallons before you need to change the media? Do you have an estimate of cost/gal to use this method? This source says 2-4 cents per gallon with DW-resin. http://www.biodieselmagazine.com/articles/8999/ion-exchange-resin-as-dry-wash-media

Actually I found some on my own. Where did you buy the column itself?

From reading at journeytoforever.org I gathered that it is good to eliminate water-washing as it leaves the water contaminated. Can you direct me to a resource where I might read more about the polishing column's function? So you put the hardwood chips in the polishing column and press the methyl esters through like a filter? Thanks for your response.

Wow, awesome. Do you have funding through GreenStart for this? If so, could you talk about that?

Are you considering opening the build of the processor to the public? If it's happening this summer then I would love to come out and learn first-hand the process of fabricating it.

Weird. Is there a way to put it back?

Thanks. In the upper left corner of a google doc there is a blue button that says "SHARE"

When you click it select HTML for Embedding or something of that sort and it generates an html code that you can copy -> paste into the page here. I had to resize it to width=1000 to make it look OK.
