Abstract

Domestic wastewater from toilets is termed as fecal wastewater or "black water" with a high organic content. Black water in Indonesia is still largely done by processing flows into the septic tank. UASB reactor (Upflow Anaerobic Sludge Blanket) is the anaerobic reactor processing with influent wastewater flow in through the bottom up through the sludge blanket. UASB reactor has the ability to treat wastewater with high organic load and tolerant of shock loads. Therefore we need the existence of a study on the effectiveness of domestic wastewater treatment using UASB. Characteristics of domestic wastewater from the black water test results in the Gabahan Village, District of Semarang Tengah, Semarang has value 3.000 mg COD /l, BOD 1.218 mg/l, TSS 1.800 mg/l, temperature of 27.03 º C, and pH 7.13. UASB reactor in this study using a continuous system. Wastewater used in this study using artificial black water that are tailored to the characteristics of the Gabahan Village, District of Semarang Tengah, Semarang. Artificial black water is made using distilled water, glucose, and kaolin.

Abstract

Domestic activities such as household (residential) result in a waste water effluent. Domestic wastewater is one of the biggest polluters of water sources. High content of organic material in domestic sewage pollution on the bodies of water increases the receiver. One indication of water contamination levels of BOD and COD is in excess of standard quality. One effective method that can be taken into consideration is the Phyto-biofilm technique to reduce levels of BOD and COD are appropriate quality standards. Fito-biofilm technology is a combination of waste water treatment using water spinach plants and biofilms formed by the honeycomb media. The study was conducted by using Phyto-biofilm reactor with a system plug flow. Based on the results of this study, found that the domestic wastewater treatment with Phyto-biofilm technique is able to lower the BOD parameter of 97% and COD 95%.

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.

Abstract

Along with the increasing number of urban population and urbanization, it will grow a lot of waste generated as well. According to the Public Works Department, the rate of domestic waste in Temanggung is 2.79 L/person/day, so that waste generation in Temanggung each day is 128m3/day. But the ministry was still 6.27%. To reduce the amount of waste generated in Temanggung had done some trash pemialahan in each house. Given the role of such a society, the waste produced by the settlement will be slightly reduced, where the waste could still be recycled back can still be useful. Based on the need to evaluate the condition of the existing waste management and to the development of waste management system in Temanggung.

Abstract

In this study, will be known ability of UASB reactors (Upflow Anaerobic Sludge Blanket) in a laboratory scale in processing the mixture of domestic waste water (grey water and black water) by varying the upflow velocity and influent concentration. Influent concentrations used are of three kinds, namely the concentrations of low, medium and high. The parameters examined were BOD5 (Biological Oxygen Demand), COD (Chemical Oxygen Demand) and TSS (Total Suspended Solid). Maximum values ​​obtained of COD removal efficiency is 69%, whereas the maximum BOD5 removal efficiency is 76%, and the maximum TSS removal efficiency is 72%. The higher the concentration of waste water, the greater the concentration of BOD5, COD, and TSS that can be removed by the microorganisms in the UASB reactor. Overall, the reactor with slow upflow velocity is allowing time for microorganisms to decompose the substrate in the wastewater, so that the removal efficiency obtained is higher. However, the results of treatment using the UASB reactor was not yet meet the quality standard (KepmenLH. No. 112 , 2003 and Perda Jateng No. 10, 2004), thus requiring further processing to be discharged into water bodies.

Abstract

The difference of Nitrogen levels  in flowKali Plumbon sea,  West Banjir Kanal and East Banjir Kanal due to the difference of utilization area. Nitrogen can be degradated by nitrifying bacteria that has been able to adapt in high salinity water. In addition to minimizing nitrogen in the sea, the bacteria can be applied to the industrial wastes water that containing nitrogen with high salinity. The water samples from the three locations were put into the reactor and the ammonium was added as much as 25 mg-N / L, and then the nitrification process have to observed for 29 days. Nitrifying bacteria obtained from marine estuarine flow West Banjir Kanal  is the most optimal bacteria than the bacteria obtained Plumbon Kali and East Banjir Kanal sea,it’s because the bacteria obtained West Flood Canal was able to adapt to the conditions of high salinity, so that the bacteria can be able to degrade ammonium to nitrite and then to nitrate faster than the two other locations.
