Effects of Hydraulic Retention Time and Solid Retention Time of POME on COD Removal Efficiency
The aim of this paper is to report on the effects of Hydraulic Retention Time (HRT) and Sludge Retention Time (SRT) on the removal of Chemical Oxygen Demand (COD) from palm oil mill effluent (POME). In this study, an upflow anaerobic reactor was used to evaluate the effects of HRT at 6, 8 10, 12...

| Summary: | The aim of this paper is to report on the effects of Hydraulic Retention Time (HRT) and
Sludge Retention Time (SRT) on the removal of Chemical Oxygen Demand (COD)
from palm oil mill effluent (POME). In this study, an upflow anaerobic reactor was
used to evaluate the effects of HRT at 6, 8 10, 12 and 15 days. In order to measure the
effects of SRT, the 10, 15 and 20 days aged sludge were used. The differences in COD
value of POME and effluent at inlet and outlet of the anaerobic reactor were used to
measure the effects of HRT and SRT. The experiments were conducted at 35oC for a
length of 60 days, and input-output data of COD were used to achieve the research
objectives. The estimated results show that the COD removal was optimum at 12 days
of HRT and the estimated COD removal performance was at 40.4 percent. It was also
found that COD removal was optimum at 20 days of SRT and the estimated COD
removal performance was at 34.1 percent. The study concluded that anaerobic reactor is
an effective method to remove COD from POME. This study recommends future
researches which aim to increase COD removal to level that is economically and
environmentally sustainable. |
