Abstract

Abstrak Concentration of nitrogen which over in waste water can caused decreased of dissolved nitogen consentration, sparked the growth of algae in the waters and be toxic to organism. One of nitrogen elimination using biological treatment is trough anaerobic-aerobic process. Research was conducted with variation of discharge for 2 mg/l, 6 mg/l, 8 mg/l and residence time variation is used to process is 24 hours, 8 hours and 3 hours. Anaerobic and aerobic process are 8 hours, 3 hours and 1 hour. The results showed that the discharge affects the process of ammonia-nitrogen and COD elimination, where the amount of discharge is inversely proportional to the concentration of ammonia-nitrogen and COD produced. Research results also showed COD concentration can be decline until 11% - 35% and ammonia-nitrogen removal efficiency by 13% - 98%. Keyword : COD, ammonia, anaerobic-aerobic process
