[Stoves] Stoves Digest, Vol 4, Issue 13

[Anand Karve]

Dear Rajan,
Transporting the wet slurry from a dung based biogas plant to the field is
always a bother. One can allow the slurry to be filtered through a bed
of straw. The water in the slurry drains out, leaving the relatively dryer
slurry on the surface of the bed of straw.  The slurry, now devoid of most
of its water is easier to handle and to transport
Yours
