| Summary: | Environmental management is an important component in sustainable
activity for industrial sector. One of the problems in oil and gas industry is produced
water. Total Indonesia E&P Balikpapan produces a produced water of 22.000-
25.000 barrel per day. Biological treatment is one of alternative method to reduce
COD, phenol, and ammonia compound in produced water. This research was done
in batch reactor to determine the kinetic process coefficient ?max and Ks, the removal
rate of COD, phenol, and ammonia compound using Epyzim commercial bacteria.
The experiments were done in 5 (five) days, and been sampled every 6-12 hours. The
results showed that the value of ?max, Ks, and Kd were 0,114/hours, 0,064 mg/l, and
0,018/hours, respectively. COD removal efficiency of produced water without
adding nutrients was 26,2-38%. And for produced water with adding nutrients to
reach CNP ratio of 100:10:1 was 30,9-39%. Ammonia removal efficiency of
produced water without adding nutrient has negative (-) value because there is an
increasing of ammonia concentraion in effluent reactor, while ammonia removal
efficiency of produced water with adding nutrients to reach CNP ratio of 100:10:1
was 76,5-91,6%. Phenol removal efficiency of produced water without adding and
with adding nutrient to reach CNP ratio of 100:10:1 were 99,8%. Reactor effluent
character in this experiment did not fulfill threshold limit accordance to the
regulation of Environmental Ministry Regulation No. 19 of 2010. Epyzim
commercial bacteria is a good phenol degrader, but not effective for total organic
compound removal represented by COD. |
