This paper presents the results of a multidisciplinary analysis and the evaluation of a suitable technological solution for wastewater treatment for the villages Backi Breg and Kolut, belonging to the Backo Podunavlje Biosphere Reserve. The research was structured as a three part methodology. It encompassed: 1) citizens? habits on wastewater production - investigated by analysing septic tank waste water quality; 2) stakeholders? opinion on the most important features which a wastewater treatment facility (WWTF) has to fulfil-analysed by interviewing stakeholders and the application of multi-criteria decision support tool and 3) finding the most suitable location for future WWTF by applying geographic information systems (GIS). The results revealed that sampled wastewaters were in range for municipal wastewaters. The decision-making model, based on simple additive weighting (SAW), was defined to evaluate two possible solutions (constructed wetland and sequencing batch reactor) across six criteria. The model showed that a constructed wetland system is more adequate, in comparison to the sequencing batch reactor. Finally, by overlapping multiple GIS map layers the most suitable area for setting up the WWTF was found. The proposed methodology is especially suitable for application in biosphere reserves, since the link social attitude - natural resources exploitation - nature conservation is the key element for achieving sustainability.

Oxygen Demand

Sebuah Sequencing Batch Reactor (SBR) digunakan untuk mengevaluasi peranan Biochemical Oxygen Demand (BOD) biosensor dalam proses optimasi proses pengolahan nutrien karbon, nitrogen dan fosfat. Hasil penelitian menunjukkan bahwa BOD biosensor dapat dipergunakan untuk penentuan karbon organik, sehingga reduksi siklus SBR dapat dilakukan dan efisiensi proses meningkat. Pola konsumsi karbon organik ditemukan dengan adanya ‘tanda diam’ pada fase anoksik/ anaerobik, di mana dari tanda ini, fase aerobik dapat segera dimulai. Reduksi durasi siklus SBR dari 8 jam menjadi 4 jam meningkatkan efiesiensi pengolahan C, N dan P yang meningkat pula (hampir dua kali lebih tinggi).
