ABSTRACT:
The present invention relates to a test procedure for evaluating nitrification activity which takes thirty minutes and accurately demonstrates a correlation of the nitrification activity when compared to ammonia nitrogen removal efficiencies. The test procedure involves treating sludge samples with an ammonium nitrogen/carbonate medium and a buffer and measuring BOD, and then adding thiourea and again measuring BOD. The nitrification activity is determined by subtracting the two BOD measurements.
