<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>
