Abstract:
This study aims to analyze and examine the effect of the use of palm fronds, and
Zeolite (NaHCO3), the processing of palm oil mill effluent, which aims to reduce
levels of COD palm oil mill effluent, to comply with quality standards issued by
the Ministry of Environmental Living No. Kep-51 / MENLH / 10/95, where‘s final
COD waste can be discharged into the environment is 350 mg / L, in this study
also determine a suitable model, the cell growth curve modeling the
microorganism used in the processing of oil mill effluent oil, as well as the impact
of the use of agents thixotropic to process the COD reduction of waste.
Results of the study showed, that the use of palm frond at 100 grams, is able to
gain COD removal efficiency of 90.6%, whereas without the use of palm fronds
only 33.3%, with a duration of 8 days diving sewage treatment, whereas the
addition of thixotropic agent, can improve COD reduction of waste by 320 mg / L
for 10 days, it is within their premises Ministry of Environment standards, while a
suitable model to model microorganism cell growth curve is Contoins model
