MODIFIKASI DIGESTER UNTUK PRODUKSI BIOGAS DARI AIR LIMBAH INDUSTRI MINYAK KELAPA SAWIT SECARA FED BATCH
Daftar Isi:
- The purpose of this research is to biogas production in the digester modification equipment by fed batch of the palm oil mill effluent (POME) to determine the quality of POME after a treatment and the concentration of biogas that is formed every 24 hours within 10 days. The raw materials used is Palm Oil Mill Effluent. In the initial stage is sedimentation process in the first digester tank at a flow rate 6 Litres/minute and then observing the retention time of 24 hours. POME flowed into the second digester tank for fermentation process with the addition of active microbes seed every 24 hours to produce biogas. After fermentation process is complete, POME flowed to third digester tank for water treatment stage before being released into the environment. COD content test values obtained after processing, namely 766, 362 and 350 mg/L, while the BOD value are 212,75, 125 and 110,9 mg/L, and the percentage of methane gas in the can are fermentation time for 10 days, 10,88% methane, 19,2% oxygen and 75,83% nitrogen.
