Rest heat sterilization is the process of instant sterilization by holding the instruments in a Bunsen flame till they become red hot. The heat can cause warping to sensitive materials or thin sheets. Ozone is more challenging to produce and deliver than chlorine. Describe the steps required for sterilization of … Moreover, ozone's reactivity makes it a toxic chemical, so operators must design plants in such a way that workers don't come into contact with ozone gas escaping from the water. The advantages and disadvantages, as well as its recommended uses, are explored in this review article. Ozone produces less THM disinfection by-products than result from chlorine disinfection (but bromate may be formed). If the water is rich in organic compounds or suspended solids, a lot of the ozone may be consumed through reactions with these other contaminants, leaving an insufficient amount available to destroy germs.
