Dear A.D.,
Transporting the wet slurry from a dung based biogas plant to the field is
always a bother.
True. But for such a problem, bio-digesters would have been one of the ideal
solutions for the " bio-degradable waste disposal " in cities ( especially
in tropical countries ).
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.
But, will not this water also contain valuable dissolved nutrients ?
May be, the water can be pumped through a pipe, and the concentrated slurry
carried using other means.
Best Regards,
Rajan
