There is a lot of literature on the safety of effluent. Basically,
at ordinary mesophilic temps, destruction of most pathogens requires
very long retention times-- months. (Parasites are more susceptible
to mesophilic digestion.) At thermophilic temps-- comparable to the
temperature inside an active compost pile-- anaerobic digestion can
destroy pathogens at more ordinary retention times.<br>
<br>
Of course, as well, rather than use a word like "destroy", which
implies a complete absence of the offending organisms, a more
scientific parlance would be to speak of reduction by factors of
ten, to levels that are considered safe, even if some members of the
species in question are still present.<br>
<br>
Regardless, at least in my view, the effluent should not be used on
land where food is grown, and it would be safest if the liquid
effluent is buried and the de-watered effluent is composted.<br>
<br>
There is, to my knowledge, only one paper extant on using dog manure
to produce biogas: Comparatiw Study of the Potential of Dog Waste
for Biogas Production, by Okomigwe et al, out of Nigeria.<br>
