<DIV>Greetings Kevin ,</DIV>
<DIV>One correction re washing -at least-fibrous dung. The fibers that would
remain ARE thee binder. The rest is infilling hopefully carbon rich 'heat
-extractable' material.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># OK!! Thanks for the "good news." I was concerned that
perhaps the fibres remaning after digestion would be relatively smooth, and
without the leached componts to act as "sticker stuff", binders would be
reduced or absent. </FONT></DIV>

<DIV><FONT face=Arial>Best wishes,</FONT></DIV>

<DIV><BR></DIV>Hello,
<DIV><BR></DIV>
<DIV>I'm looking to clean/rinse cow dung and do not have any experience
doing so. Does anyone have any experience cleaning dung and would
like to share? </DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># I've never done it, but I think it is a good idea,
requiring further development work. Big thing is to have use for the "wash
water". </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial># Simplest thing would be to slurry the Manure/dung
to remove solubles. Solubles could be simply decanted, or the remaining
pulp could be filter pressed to get a drier cake.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial># Removal of the soluble protein, salts and
micronutrients should allow the remaining fibre to be dried easier, to
have a higher calorific value, and to burn safer, with less risk of dioxin
formation. Washed dung could be briquetted in a simple press, but the
washing process would probably remove the natural "binders", and thus a
binder of some sort may have to be added. Richard Stanley has done a lot
of work on manufacturing fuel briquettes from various locally available
biomass feeds</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial># On the one hand, the "dung wash water" could make
an excellent "Fertigation Feed." On the other hand, depending on dung
source, soil type, local rainfall, crop being grown, intensity of use,
etc, there may be a problem with salt buildup in the soil.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
