Abstract

Anaerobic digestion was developed to treat high concentration organic compound efficiently in certain Digestion Time (DT). High ammonia concentration could influenced removal organic compound in digestion. This bench scale study investigated the effect of digestion time on anaerobic batch reactor with high ammonia concentration. Total Ammonia Nitrogen (TAN) concentration was adjusted 4000 and 5000?mg/1, Digestion time was ranged from 0-26 d, operation temperature was ranged from 28-29°C, inoculum was collected from slaughter house sludge. The degradation of Chemical Oxygen Demand (COD) correlated with digestion time. The concentration of TAN from synthetic wastewater contain 5000?mg/1 of TAN more fluctuated than those use 4000?mg/1 of TAN. However, the biogas production from wastewater contained 4000?mg/1 of TAN gradually increased until 24 d of DT. The reactor contain 5000?mg/1 of TAN only growth until 12 d and steady state at over 12 d of digestion time.
