Abstract

Fixed Bed Reactor was the biological wastewater treatment reactor that
was one of the Cakung Slaughterhouse (RPH Cakung) wastewater
treatment. Biological wastewater treatment process in principle was
process use of the microorganism to degrade the wastewater pollutant,
where the wastewater will be changed into gas and the particle bio-solid
that enabled to be sediment. The capability of the microorganism
degrading this pollutant was influenced by various factor, some among
them were the distribution of the substrate (microorganism group) in
the reactor. The distribution of this substrate could be known by
measuring the value of pH and organic content as Chemical Oxygen
Demand (COD) or Total Solid (TTS). Considering the importance of the
parameter then must be keep so that both of them, did not exceed
limits that were allowed in the FBR operation. This paper was discussed
by the condition for the distribution of the substrate in various hydraulic
retention time (HRT). Analysis was held for the operation with the up-
flow system. Results of the research could be known that the value of
the pH and TS in various HRT relatively constant, that is between 6.93
– 7.15 (for the pH) and 0.32% - 0.56% (for TS). This value is still in
limits that were allowed. This showed that the FBR reactor had the
good performance was inspected from the condition for the distribution
of the substrate inside.
