Abstract

Greenhouse gasses (GHG) that produced by anaerobic digestion of wastewater consists of CH4 gas and NO2 gas. Beside the data of specific activity, the specific emission factor also plays important part to determinate GHG emission. The aim of this paper is to know specific emission factor value from communal wastewater treatment plant (WWTP), as an input to determinate GHG emission for determination of GHG emission reduction rate. The data was collected by taking sample of BOD, CH4 gas, and CO2 gas from communal WWTPs. Sampling location were communal WWTPs in Jakarta City, Bandung City, and Yogyakarta City. Those WWTPs using anaerobic baffle reactor as their treatment system with capacity varied between 40-200 EP. The parameters were BOD and CH4 that measured using grab sampling in the morning and evening. Data analyzed by quantitative methods. The specific emission factor value was determined from CH4 gas measurement which affected by wastewater treatment unit dimension, gas catcher chamber, and air suction pump capacity. The analysis results showed specific emission factor for communal WWTPs from the three cities is 0.00171 kg CH4/kg BOD. The value has bid difference when compared to IPCC’s default that is 0.48 kg CH4/kg BOD. This is due to the formation of CH4 gas and CO2 gas was strongly influenced by environmental condition in real time condition. This factor is not taken into consideration in IPCC’s default.

Abstract

The sanitation development target that everybody has access to sanitation infrastructure has not fulfilled yet, and only 65% of 146 units of septage treatment plant operated well. These conditions need to be improved and the first thing to do is analysing existing condition and composing scientific information as a reference for implementation. The aim of this research is to map the condition and management status of septage treatment plant system in 8 cities selected. This research was conducted by assessing the content of septage treatment technologies using technology atlas approach, which consists of elements technoware, humanware, infoware and orgaware. Mapping carried out on two types of septage treatment plant, that uses Imhoff tank and Anaerobic Baffle Reactor (ABR). Mapping was also conducted on the status of rehabilitation and operational conditions for each septage treatment plant.The results of this study concluded that the sophistication level of septage treatment technology is a medium category with coefficient contribution is 50%. Operational conditions of septage treatment plant is almost optimum with the  ability of septage processing is 54%.  A recommendation to increase the performance of septage treatment plant are : improving septage supply, improving the maintenance quality of processing units, improving SOP quality, sharpening tasks and responsibilities as well as improving human resource competencies.

Abstract

Domestic wastewater pollution in the watershed area which has ecologically sensitive area, such as peat water, can be resolved by water management that combines raw water treatment and wastewater treatment with closed loop system on a community scale. This paper describes the removal characteristics of organic and nutrient in biofilters loop system to treat raw water that contains color <300 units PtCo, COD 102-116 mg/L, and domestic wastewater. Water treatment system which consists of a biological treatment and multimedia filtration is used to supply drinking water and to conduct wastewater treatment on a community scale by using the potential of ecosystems and chemical-physical characteristics of peat. The study was conducted by applying method of field scale to serve 50 families and method of performance evaluation models based on approach of first-order kinetics plug flow and Kadlec and Knight k-C* model. The case study is located in downstream of Siak watershed areas, as one of the national strategic watersheds, which is packed with urban slum areas with low access to surface water utilization and good sanitation infrastructure. Water treatment unit that consists of peat biofilter systems, hybrid aerobic biofilter, and zeolite cation-anion filtrationcan support water supply in public sanitation facilities. The biofilters loop model for wastewater treatment consists of hybrid Upflow Anaerobic Sludge Blanket (UASB), biofilters, and constructed wetlands which its media is a combination between porous media and peat soils. At steady state, the removal of organic and nitrogen is larger than 90%.
