Design Of Biogas Electicity Generator Pilot Plant by Cow-Palm Plantation Integration
MetadataShow full item record
Wastewater treatment utility is one of the most important components in the palm oil production. This utility is normally used to treat a large volume of palm oil mill effluent (POME) generated during the production of crude palm oil (CPO) before the effluent is safely discharged to the surrounding environment through water ditches or rivers. The production of POME in Indonesia is estimated around 28.7 million tonnes per year. Most of the palm oil mills use the conventional pond system to treat their POME. However this system has many disadvantages such as: long retention time (90-120 days), large area required, high demand for maintenance, loss of nutrition and high emission of methane. Previous research at the laboratory scale have produced large volumes of biogas and high decomposition rate of COD, however prior to be filled to the fermentor tank POME should be supplied with ammonium bicarbonate as a nitrogen source. In order to be applied to the industry, this method should find out the alternative nitrogen source which has the criteria such as; cheap, easy to obtain, and available at any time (continuity). One of the nitrogen sources which fu lfill this criteria is cow manure or dung. The objective of the project is to design a more efficient POME treatment plant using an anaerobic continous stirred tank reactor (CSTR) in the pilot plant scale. The produced methane gas will be used to generate electriCity with a capacity of 15-20 kWh. For natural nitrogen source cow manure will be used, and in order to obtain them easily and cheaply, cow-palm plantation integration concept will be adopted. Biogas electriCity generator pilot plant will be operated by applying a variation of hydrolic retention times (HRT), namely HRT 10, 8, 6 and 4 days. Quality and quantity of the produced biogas will be recorded daily on each HRT, produced electricity will be recorded as well.
