5The key process stages of Anaerobic Digestion
- Anaerobic digestion is a complex biochemical
process. - Consisting of reactions by various
microorganisms. - They convert organic compounds into methane and
carbon dioxide. - It is a stabilization process, reducing odor,
pathogens, and mass. - The microorganisms are Temperature PH
sensitive. - Optimums -- 99 to 105 degrees _at_ PH of 6 to 7

19 IBR Digester Technology
The IBR Induced blanket Reactor, consists of
above ground tanks. Developed by Utah State
University
- The tanks have a septum in the top with a
patented plug control mechanism that is able to
retain the solids and the slow growing bacteria.
- The submerged septum in the top of the vessel
causes a sludge blanket or bed to form in the
lower portion of the vessel.
- This sludge bed becomes mostly living
bacteria that the influent has to travel through
thus putting the influent in contact with the
bacteria.
- The tanks are always full and are designed as
a flow-through system. As influent is pumped into
the bottom of the tank effluent flows out the top.
- The system is a modular design and can easily
be adapted to small or large farms. Failed tanks
can be isolated and fixed.
- Controlled Temperature
- Retention time, 3 to 5 days.
