-ase of ozone production from air or oxygen by

electric shoc.

Ozone is highly corrosive and toxic.

-ase 2eaction with organic and inorganiccompounds because of their high reactivity andreduction potential .

3he initial cost of the e4uipment is highgenerators re4uire much energy .

the Ozone reduces 3O5 , color , odor andturbidity of treated water.

Ozone must be generated 6in situ6 by probin storage and transportation

Ozone oxidizes iron, manganese and sulfides. 3he half life of ozone in the distribution syst! minutes at room temperature , soozonation does not ensure clean drining w

being necessary to add chlorine.

one of the most efficient chemical disinfectants ,as it re4uires a little time contact.

89:s are formed in the presence of bromaldehydes, etones , etc.

In the absence of bromine, are not formed 89:s.

filters are re4uired for removing actibiodegradable organic carbon

Ozone is more effective than chlorine,chloramines and chlorine dioxide to inactivateviruses, 5ryptosporidium and ;iardia .
