We got fairly good results by putting piggery effluent onto a
gravel pad and letting it drain (once we got the digester going
well). See <a class="moz-txt-link-freetext" href="http://www.youtube.com/watch?v=JCJyyA8LlnY">http://www.youtube.com/watch?v=JCJyyA8LlnY</a> for a South
African view.<br>

Happy digesting,<br>

<p>Thank you Kyle & David<br>
Your quick responses are appreciated & give me more hope
that it will work.<br>
Kyle. <br>
1. On temperature. We in Southern Africa are into the hot
season, so that will give us time to run our trials, but my
reading indicates that a 10 C drop in temp from 38 has a
significant effect on the time the manure has to stay in the
bag.<br>
As it is, I guesstimate that I would need about 150 bags! As I
don't need the gas, (except to dry the effluent), I will try to
heat the bag.<br>
2. I don't think delivering liquid will be an option. There are
machines that are available (at a cost!), to extract water to
about 40%. Water removed would be re-used.<br>
3. Larger digester. I am worried that the larger the digeater
the more likely there will be 'dead zones' & its not so easy
to agitate a bag. I would welcome any more infprmation on this.<br>
4. Pebbles in the droppings. This is a very valid point for me.
Although are birds are in cages, are floors are earth so I will
have to use a system of mix, settle & then pour.<br>
David.<br>
1. That the effluent does not attrack flies is music to my ears!<br>
2. I accept that a bag is short to med term, but I need to start
trials & anyway hopefully others in the world will be
re-inventing digesters, within reason the longer I wait the
better chance I have of getting the most up to date system.
Interesting about Kenya having made so much progress, when I
left in '69 nothing had started. I may well have to pay a visit
to see a med size one working.<br>
3. Due to very limited space we can not 'lagoon' the liquid, nor
can we get the dry grass etc to make compost. I will have to
find a way to dry it sufficiently to sell.<br>
Thank you both for your ideas & time, & ask if anyone
else has experience on drying the effluent.</p>
