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. Treatment of artificial black water using UASB, the value of efficiency for COD reduction ranged from 35.26 to 52.71%, ranging from 27.71 to 53.58% for BOD5 reduction, TSS reduction ranged from 35.38 to 76.36%.

Abstract

ABSTRACTThis research is aims to reduce the content of total coliform bacteria in domestic wastewater using a combination of vertical flow roughing filter (VRF) and horizontal flow roughing filter (HRF) for each variation of flow rate, the type and the size of filter media. Domestic wastewater influent is used as an artificial wastewater containing total coliform bacteria sample 2400 MPN/100 ml. The results of the best drop reaches 0 MPN/100 ml sample contained in VRF combination with medium-sized fine charcoal filter (10 mm,6mm and 3mm) on the flow rate 0.0926 liters/hour.Variations in discharge and the size of filter media for total coliform bacteria indicates a decrease inversely proportional relationship, where the smaller size of the discharge and the filter media decreased total coliform bacteria. As for the type of filter media, charcoal filter media types work better than gravel to reduce the content of total coliform bacteria.

As an independent region, BSB’s developer shall provide waste management facilities. To increase its purpose and economic value of waste, treatment is necessary, Material Recovery Facility can be an alternative. Thus, the design of waste management and the concept of MRF needed.To design a waste management master plan, evaluating existing systems, sampling to determine waste generation and composition with SNI 19-3964-1994 are needed, then subsequently designing the independent solid waste treatment with MRF system and calculates the required budget plan.Evaluation result shows that the management of solid waste in BSB is quite well but not in accordance with SNI 3242:2008 of Residential Waste Management and SNI 19-2454-2002 of Operational Techniques of Municipal Solid Waste Management. Sampling results show that people in Bukit Semarang Baru produce average waste by weight of 0.64 kg / person / day with a volume of 3.65 L / person / day, thus having density of 175.51 kg/m3. BSB waste composition comprising 53.95% of organic waste, paper (9.26%), HDPE (8.45%) Other (7.64%), PP (4.02%) and PET (2.30% ) glass by 2.94%, 1.54% metal, wood and 1.36%, PS (1.08%), LDPE (0.09%), and PVC (0.00%), and other junk (7.37%). Solid waste management that will be applied in BSB consist of separation from the source, individual indirect collecting system with transfer station in BSB Jatisari, while BSB Mijen implement curbside collection system. Treatment of solid waste include composting or organics, briquettes processing, plastic rope spinning, size reduction and baling of plastics, cans and paper. This system requires an investment of Rp 4.661.599,00 with profit to Rp 9.419.793,00 per year by 2025.

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%.
