[Digestion] question about digestion of Vodka Draff

[thecogas at cs.com]

Hello All,

Does anyone have experience with the digestion of residues from the 
production of Vodka? And does this give a high amount of H2S in the 
biogas which cannot be removed by simple blowing in a small amount of 
air?

I seem to get confusing answers. Some say it is notorious for high 
hydrogen sulfide levels, others say it doesn't .

Hope you can help me,

Theo Bijman
