| Treatment for bacteria and sediment includes ozonation, ultra-violet irradiation and filtration. |
| Early work has shown that the effects of ozonation, prior to chlorination, depend on treatment design and raw water quality and thus are unpredictable. |
| Current treatment options to remove the toxin from drinking water include ozonation and carbon absorption. |
| This limits cooling water temperature for adequate application of ozonation. |
| Iodinated contrast media are among the compounds found most often in drinking water, since they generally persist after activated carbon treatment as well as oxidation processes such as ozonation. |
| Cryptosporidium microorganisms are chlorine-resistant and can be filtered and disinfected through microfiltration, ozonation and UV disinfection. |
