Abstract

Microbial Fuel Cell (MFC) technology has attracted interest for its dual role in wastewater treatment and energy generation. Aim: This study aimed to evaluate the performance of a Modified Septic Tank-Microbial Fuel Cell (MST-MFC) for office domestic wastewater treatment, focusing on organic matter, ammonia removal, and electricity generation. Methodology and results:  In this study, synthetic wastewater was prepared to simulate the typical composition of domestic effluent from office buildings. The main variables measured in this study included pH, temperature, Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), and ammonia levels. A 196 L reactor (36 h HRT) with anoxic, anaerobic, aerobic, and sedimentation zones was equipped with three pairs of zinc–copper electrodes (2 cm spacing) placed in anaerobic (anode) and aerobic (cathode) chambers. Synthetic wastewater with controlled COD:N:P ratios was applied at two organic loading rates (OLRs): 7 and 11.94 mg COD/L.h. At the lower OLR, COD removal reached 100% versus 93.85% at the higher OLR. Ammonia removal was also higher (27.61% vs. 17.59%), while electricity generation peaked with 461.88 mV, 355.67 mW/m2, and 0.0970% Coulombic efficiency. Conclusion, significance and impact study: The MST-MFC showed strong potential for decentralized wastewater treatment with energy recovery, though limited ammonia removal indicates further optimization is needed, with OLR as a key factor.

Abstract

Domestic wastewater generated from various types of buildings has been recognized to be different to some extent. This research aimed to know the quality, quantity, fluctuation of quality, and fluctuation of quantity of domestic wastewater discharged from office buildings. The composite samples were taken from two office buildings. The black water and gray water were taken from Building A with number of people 53 persons, and the mixed wastewater was taken both from Building A and Building B with number of people 900 persons. The fluctuation and quantity of wastewater were measured every hour from 7 am until 4 pm during the working time. The results showed that the quality of wastewater from office building contained 176 to 238 mg/L COD, 73.06 to 106.51 mg/L TN, and 3.66 to 7.70 mg/L TP with the average of C:N:P ratio was 100:42:2.56. Quantity of wastewater discharged from office buildings were from 39.61 to 49.93 liter/person/day. COD concentration changed significantly during the working time with mean ± standard (252.5±89). The quantity of wastewater varied over time and the peak discharge for black water and gray water were 2.85 litter/person/hour and 3.74 liter/person/hour, which occurred during the beginning of working time and the praying time of muslim Indonesian culture. It suggests that the domestic wastewater from office buildings has specific characteristics and it contains high concentration of nutrient that is required appropriate advanced technology for treating this kind of wastewater.

Abstract

Currently, 24.5% of the population of Bima City lack access to sanitation. The issue is predominantly concentrated in densely populated urban slums along the riverbanks, influenced by the cultural and societal context of Indonesian society. From 2021 to 2022, a comprehensive mixed-method study was conducted in three urban slums, applying the Integrated Framework for Sanitation Services (IFSS) to explore individual aspects within a socio-cultural context. Combining quantitative and qualitative methods, the research involved a household questionnaire survey and in-depth interviews (IDI). The study revealed that individual aspects are shaped by perceptions of the convenience of open defecation and latrine use as well as experiences with shared latrines, driving the adoption of private latrines. Challenges such as financial constraints and limited construction capabilities in urban slum communities often hinder latrine construction, though cultural and traditional values (adat) in the Bima community in urban slums help to alleviate these obstacles. A recommendation is made to enhance the monitoring of sanitation adoption progress, focusing on the sanitation system’s functioning and adherence to the sanitation hierarchy. Despite awareness of the importance of safe disposal, its impact on sanitation behavior in Bima City’s urban slums has been constrained, underscoring the imperative for effective behavior change communication strategies.
