experience growth to form granular sludge biomass.
Granular is a form of biomass that has a diameter of 1-
5 mm and large densities. So have a good ability to
settle. This requires the formation of granular sludge
process control with the requirements of specific
operating conditions and the addition of specific
micronutrients that lasted a relatively long process
depending on the characteristics of waste water
treated. Granular condition is achieved when the
situation is steady state which can be identified by:
Fluctuations COD reduction efficiency is
relatively stable
Ratio (value ratio) against the concentration of
volatile acid concentration is 0.1 alkalinity or
pH values fluctuate in neutral pH region, ranging
from 6.8 to 7.5
Needs of the energy used in the anaerobic UASB
system is relatively similar to anaerobic filter system. UASB
anaerobic systems can operate on organic load 10-30 kg
COD/m 3 , today. Efficiency of wastewater treatment of pulp
and paper industry can be achieved by 80-85% in reducing
pollutant COD. Production of methane (CH4) formed at 35
o C is 0.41 l / g COD reduction. Based on the results of the
efficiency of wastewater treatment has been applied in the
pulp industry achieve COD reduction of 80%, while the
methane gas composition reaches 55-70% or with the
production as much as 0.3 to 0.4 m 3 /kg COD reduction.

In general, emission of gas produced in wastewater
treatment contained in the processing systems and
