STRATEGI OPERSIONAL SBR(SEQUENCING BATCH REACTOR) SECARA AEROB- ANAEROB PADA PENYISIHAN KARBON DAN NITROGEN

Abstract

In Biological wastewater treatment by using SBR occurs removal carbon and nitrogen on the system. The removal carbon and nitrogen are influenced by the strategy of operational and ratio C/N. This research purpose to decide strategy of operational aerobic-anaerobic and ratio of C/N removal of carbon and nitrogen. In research was used reactor from plastic material with diameter 25 cm and high is 25 cm, volume of wastewater in reactor is 5 liter and volume of sludge is 35% from volume of wastewater that 1,75 liter. Waste that used was artificial waste glucose soluble with 1013.9 mg/l concentration of COD. As independent variable are strategy of operational: (aerobic-anaeroicb; aerobic-anaerobic, aerobic-anaerobic; aerobic-anaerobic, aerobic-anaerob, aerobic-anaerobic) and ratio of C/N (100:5, 100:15, 100:30, 100:45, 100:60), if dependent variable are removal of carbon and nitrogen. As the result this research shows that the finest of carbon removal is occurred in strategy of operational aerobic-anaerobic, and ratio of C/N (100:5) is 97.93%.. The finest removal of nitrogen on form ammonia is occurred on strategy of operational aerobic- anaerobic, aerobic-anaerobi, aerobic-anaerobic, and ratio of C/N (100:5) is 98.04%.
