Digester Project,
Sunday, October 21, 2007
We would like to express a
great deal of thanks to Mr. Gerry Baron
for his design work, expertise and
especially his patience.
Also a great deal of gratitude goes to
Eugene Jovito for his creativity,
innovativeness and help in seeing the
project completed.
Plus all the workers involved in the
project and I truly mean workers!
They showed up faithfully on time
every day rain or shine and we had
lots of rain to contend with. BUT, they all came to work and work they did;
we were very fortunate and extremely
lucky to be blessed
with such a good crew.
Digester Specs:
3M long, 2.2M wide and
2.65 meters below ground
with .7M above ground making the total
size 22 CM.
1.
Digging the
hole, we hit water at two meters and it was a mess.

2.
Lots of dirt
stacked around the hole
3.
We had so much
dirt it had to be moved to a further location
4.
The block
makers: Decided we wanted more strength than you
can get using commercial blocks so we
made our own

5.
In spite of
the water problem the foundation was poured along with the floor.
Because of the digester depth it was
decided the floor should be 20CM
6.
What a mess;
final depth is 2.65 meters with the floor in place.
Every morning water had to be pumped from the hole before
work could begin
7.
Water problem
solved and the walls are starting to take shape.
Walls and posts were done in three
segments

1.
Plastering the
inside
2.
More
plastering. An idea just how deep and
how big the digester is
3.
Rebar for the
top of the digester

4.
Lots of
concrete for the top, 13 CM
5.
Inside the
digester
6.
Workers inside

7.
Shoring and if
you look closely you can see the bottom
8.
Construction
of the slurry chamber

9.
was removed and the inside was painted
with a sealer &
then with external latex paint.
10.
Funnel that
inserts into the inlet pipe.
11.
Covers for the
slurry pit

12.
What’s
this???? Are we making biogas
13.
Unbelievable!!!!! We had a bit of a flame six hours after
pumping
septic tank into digester. Photo taken with flash
14.
Huge flame again
at 71/2 hours (with no flash used.)
Boiled water
right after these
pictures were taken.

15.
WOW!!! What a
system, very functional and simple to operate
This
has been a real adventure, one a bunch of people will never forget.
I know the memories of this will be
with Lorina and me forever.
Again
thank you Gerry Baron, Eugene Jovito, Ruben Aninipot and the crew,
Rudy Sicad, Isigani Jetajobe, Conrad Jetajobe, Vicente Laureta,
Renren Laureta, Tantoy Jeresano, Emman Janoras, Marlon Laureta,
Rommel Janoras and Rambo Laureta.
Without your help and hard work it
would not have happened.
Next,
phase 2 ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
Editor’s Notes:
The
digester above at 22 m3 (cubic meters) is larger than the HBS.
It will be used for a larger
backyard pig farm. It was built as a heavy duty
(not a low-cost) unit. However,
all the design concepts of the HBS were used.
