The 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

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.
