Modeling Kinetic Growth Rate at Effect of Palm Oil Fronds and Zeolite (NaHCO3) Utility in Palm Oil Mill Effluent Process Treatment
(2016-04-22) Bowo, Ari; Amri, Idral; Ahmad, Andrianto
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
