Notes

In the activated sludge treatment plant of Onoda City, bulking has often been caused by filamentous bacteria, types 021N and I-2. Bulking disappeared when Trochilioides recta increased in the mixed liquor of the aeration tank. T. recta was observed to ingest types 021N of I-2. It may therefore be anticipated that this type of bulking could be controlled by T. recta.
