In the digester there is an anaerobic process
by the bacteria, so the waste can break into biogas estimated within 1 week (No 1).
The advantages of an anaerobic process
are that it has low energy consumption and can produce energy itself.
Angelidaki, "Hydrogen and methane production from desugared molasses using a twostage thermophilic anaerobic process
," Engineering in Life Sciences, vol.
Generation of methane via anaerobic process
is an appropriate solution for food waste management.
An increase of temperature favours the anaerobic process
by increasing the anaerobic bacteria activity and therefore C[H.sub.4] and C[O.sub.2] emissions are increased.
The anaerobic process
enables us to obtain a biologically stabilized effluent with fertilizing properties that is hygienically safe.
UASB uses an anaerobic process
whilst forming a blanket of granular sludge which suspends in the tank.
In addition, studies by Poh , Choi  and Zinatizadeh  also demonstrated the success of anaerobic process
to treat POME.
"Combining Omnitek's technology with the abundance of biogas derived through this innovative anaerobic process
offers significant economic and environmental benefits to the agricultural industry.
In his "The Origin of Cancer" (Science magazine), he observed that most cancer cells predominantly produce energy in an anaerobic process
rather than the aerobic process used by most normal cells.
For HRT of 0.1 days, VFAs/TA was 0.24 which showed a disruption in anaerobic process
due to low HRT.
