Relationship between the pH and the rate of nitrification in aeration tank for activated sludge was investigated. 1) For the determination of pH and nitrogen compounds of mixed liquor in the aeration tank, samples must be filtered at each sampling time. 2) The pH of the mixed liquor in the aeration tank decreased with increasing rate of nitrification, and increased with decreasing rate of nitrification. 3) While the nitrification was in progress. pH decreased in the order of the mlet, middle, and outlet of the aeration tank. 4) There was a good negative correlation between the rate of nitrification and the pH of the mixed liquor in the aeration tank. It was suggested that the pH could be used as an index to estimate the rate of nitrification of the mixed liquor in the aeration tank.
