Hi Nikolaus,

You suggest some interesting possibilities:

I'm not sure that the smoke water you and I know is the same as gasifier 
condensate, or it might be heavily diluted. Gasifier black liqueur as 
drained, will kill growing weeds and grass.  I am referring to condensate 
that has tar or oily rainbows floating on the surface.

Could you advise how this might be done in a tank, so that we might say, 
fill the tank with charcoal instead of soil, and pore the black stuff in the 
top, and then drain the clean water out the bottom?  Is this a possibility, 
or do we need soils bacteria to make it work, or can we seed the charcoal 
with bacteria from some source?

The reason I ask these questions, is to help identify effective, but basic 
solutions for gasifier condensate disposal.  As I have some capability to 
develop this type of application, it will be interesting to see how it 
works. The only problem, is I don't make black liqueur (:-)
