Abstract

Fish waste is a problem arising from the activities of the fishing industry. In General, fish waste containing organic compounds are high, therefore, sewage treatment needs to be done to minimize waste. One of the technology for processing waste, namely by means of the creation of biogas by anaerobic. The advantage of this treatment is to produce a little mud than reprocessing in aerobics. This research aims to analyze the influence of addition of rumen of biogas production, the influence of dilution of biogas production and biogas production influence of stirring. This research was conducted in laboratory scale by using a typical analysis for digester capacity 500 mL. The sample used is a waste of the Stingray fish smoking industry, using a sample of mashed and not mashed as well as extracts of bovine rumen as a starter. Water used for dilution in the study is well water with salinity levels of 7.6 ppt. on variable dilution, yield the most high biogas contained on the dilution of 37.5 mL. For the addition of rumen biogas results higher than without the rumen. Stirring 3 times more effective for producing biogas is higher compared to without stirring and stirring 1 time.

Abstract

In this study using a mixture of domestic wastewater. Parameters to be researched is the Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD) and nitrate-nitrogen (NO3-N). Alternative anaerobic treatment is to use UASB (upflow Anaerobic Sludge Blanket) . This study performed a variation of Hydraulic Loading Rate (HLR) and the influent concentration to obtain the optimum conditions on an UASB reactor laboratory scale for removal BOD5, COD and NO3-N in a mixture of domestic waste water (grey water and black water). Pollutant removal efficiency by varying the influent concentration and HLR for BOD5 was about 57% -76%, for COD was about 59% -69% and NO3-N was about 75% -98%. The results is the lower influent concentration will decrease removal efficiency that occurred on the parameters of BOD5, COD and NO3-N. The maximum removal efficiency on the parameters BOD5 and COD occurs when HLR low at 0.025 m3/m2/hour or 6.94 x 10-6 m / s. While the maximum removal efficiency of NO3-N occurred when HLR high 0.05 m3/m2/hour or 1.4 x10-5 m / s.  Removal for BOD5 optimum occurs at low concentrations are 419 mg / l with a variation HLR of 0.05 m3/m2/hour  or 1.4 x10-5 m / s,  for COD occurred at low concentrations are 878 mg / l with a variation HLR of 0.025 m3/m2/hour or 6.9 x10-6 m / s, and NO3-N concentration was occur in the 36 mg / l with a variation  HLR of 0.033 m3/m2/hour  or 9.2 x10-6 m / s. The results of treatment using UASB  still above the standards that should UASB be used as a secondary treatment  to obtain the effluent below quality standart.
