2021 : Application of Sequencing Batch Biofilter Granular Reactor (SBBGR) on Hospital Wastewater Treatment
Adhi Yuniarto ST.,MT.,Ph.D
Hospital wastewater was everything that was left from any activities in the hospital, including human waste, which may still be containing microorganisms, toxic waste, radioactive, and blood that could do harm to human health. Complex processing based on the variation of steps was needed to get an effective effluent. In this study, removal of organics, ammonia, and phosphate was done using a lab-scale with Sequencing Batch Biofilter Granular Reactor (SBBGR). The wastewater that used in this research was taken from the inlet unit of a wastewater treatment plant of a general hospital in Surabaya, Indonesia. Variation of attached growth surface area and variation of aeration duration were used in this research as the main variable. Variation of bio-balls surface area were 3.6; 4.4; dan 5.3 m2. While variations of aeration duration were 8; 12; and 18 hours. This reactor using an up-flow system. Corresponding analysis that used was based on Indonesian National Standard. The preliminary test of this study included seeding and bacteria acclimatization, due to the importance to know the characteristic of the hospital wastewater. The results showed that the removal efficiency of COD, Ammonia, and Phosphate were about 77 %, 90 %, and 65 %, respectively.
