[Digestion] Digestion Digest, Vol 21, Issue 4

[stan simon]

I would be interested in reviewing your design.  We can read a pdf file or 
dwg format.

What kind of studies have been done on duckweed?  I assume you are referring 
to the Lemna (major or minor) species. A small plant that grows on the 
surface of still waters.

>> Hi All,
>>
>> I am building a small algae raceway to see what kind of production I can
>> get. I intend fermenting the algae and distilling off the ethanol prior
>> adding the residue to an AD. The biogas will be used for heating the
>> still to get off the ethanol. The digestate will be added back to the
>> algae pond as nutrient. I also intend adding cow manure to the AD as an
>> additional source of nutrients.
>>
>> I have my own design of this digester and would appreciate it if anyone
>> on the list would be willing to give me feedback on the design. We are
>> about to start clearing the site to build the digester and I want a last
>> review before committing.

>> Kind regards
