N2  - Potential of nutrient removal in Intermittent Activated  Sludge Process w s studied with three laboratory - scale reactors  by using synthetic wastewater containing organic matter and  am onia as sub tr te. Three difrerent oper ting strategies were  applied in order to find the potential of nitrogen and  phosphorus r mova1. Different duration of anoxic/ naerobic.  anoxic nd aerobic phases were applied in three reactors of each  strategy. Based on the results fro this study. nitrifying  b ct ri w re able to urvive and a1 0 gav satisfactory  perform nce under th equence of anoxic - aerobic environment.  Applying sequence of noxic - aerobic ph ses in the reactor  during long period of substrate fe ding can get the relatively  high nitrogen re ov 1 efficiency. Nitrogen removal by endogenous  denitrification lso play significant role in the strategy  where short feeding period was used. Biological phosphorus  removal, so called "luxury uptake". was not ob rved in this study. High removal (95 - 99%> of TOC w maintained in all  three str tegies of inter ittent activated sludge process.
