Dear Johan,
We are cooperating with a local non-profit organization of Dokars'
drivers to carry out a project on processing horses' wastes to produce
biogas. The side product is high-water-content slurry. The
slurry will be filtered using a conventional way (rock, sand, etc)
into its solid and liquid forms. The solid form will be used as
organic fertilizer (for sell) and the liquid will be used to irrigate
bananas trees. My concern is that whether the liquid is safe for the
environment when applied directly (whether to the banana or dump
into river). This kind of practice have been common for the farmers
who own biodigesters in Boyolali and Salatiga.
We are also planning to treat the liquid using duckweed (a kind of
minute aquatic plant). However, I will still have the same concern
whether the treated liquid is safe for the environment. If it is safe,
then it would be probably beneficial to use the water (liquid) for
fish culture! Duckweed itself could be used for chicken and cows feeds.
What I need to know is what chemicals contained in the liquid,
especially those poisonous heavy metal. So, could you do that, to analyze
the chemical contains of the liquid? If yes, what should I do from my
part? And do charge for the service?
Thank you
Djoni
