May I suggest we adopt the terms "solid digestion" (for substrates
that won't flow, moved by front end loader) and "liquid digestion"
for the more conventional pumpable substrates - all anaerobic
digestion needs moisture, only the amount varies! There is no such
thing as "dry" digestion as drying is a method of stopping
degradation. If we can't get reasonable terminology ourselves how
is the general public going to understand what we are up to?<br>
<br>
Happy digesting,<br>

Hi Robin,<br>
The dry vs wet debate may re-ignite!<br>
<br>
What I would assert for your planned AD system is a fairly wet
mixture from the start. Generally cheaper to keep it the way it
comes out of the digestate pipe. Dry would be nice, but who would
come to build your plant and at what cost?<br>
<br>
If you could find resellers of Kompogaz, BECON or Dranco, it would
be good for you. I'm only aware of CEM Engineering that did some
AD work in S. Africa, but its a liquid system.<br>
<br>
Have you considered a solid-liquid digestate seperator combined
with UF and flocculation system? <br>
Give us more info on size or scale and amounts of feedstock coming
in. If its still the case for grid connection deadlines in
Germany, engineering firms may be looking for work past that
deadline and most of them have an internationnal portfolio.
Foremost, they are always interested to work in countries where
the waste stream is full somewhat free organic waste to digest -
why send to a landfill!<br>
<br>
Good luck<br>
