Abstract

This paper assessed the potential biochemical oxygen demand (BOD) footprint, which limits number of population to dispose wastewater into receiving water and maintained aerobic conditions. Methods were based on human activities in the form of aerobic respiration process for obtaining BOD footprint due to domestic wastewater. Subsequently, BOD footprint due to wastewater conversion in receiving water was assessed for aerobic and anaerobic processes. Results for the city of Surabaya revealed that complete anaerobic conditions of receiving water would be achieved for the maximum population number of 180,000. In order to maintain aerobic conditions of receiving water, the total population number of 3,000,000 dictated to treat wastewater before disposing into the receiving water. The results suggested to provide wastewater treatment that covers 100 inhabitants. Using the unit BOD production of untreated wastewater of 45 g/person/day and the unit BOD production of treated wastewater of 1.33 g/person/day, then the decrease of the unit BOD represented the treatment efficiency of 97 BOD removal.
