Abstract
Ozone application at low level seems to be a good treatment to control bulking. The best treatment can be 0.5 to 1 mg O3/g TVM.h (total vola tile matter.hour); phi(R) = 30 min. The injection of the ozone is into the recirculation sludge pipe. It is possible to improve the settling and obtain good reduction of the dissolved organic matter. The mechan isms of ozone's action on the sludge is approached by the determinatio n of byproducts: amino acids, sugars, phosphorus compounds.
