Question
What is the efficiency of drinking water disinfection methods, reported in log-clearance?
Answer
Rationale
Data
| Method | Campylobacter | E.coli O157:H7 | Rotavirus | Norovirus | Cryptosporidium | Giardia |
|---|---|---|---|---|---|---|
| UV | [1] | [1] | [1] | [1] | [1] | [1] |
| Chlorination | [2]; [3] | [4]; [5] | [6] | [7] | [8] | [9] |
| Ozonization | [10] | [10] |
| Obs | DisinfectionMethod | Pathogen | Unit | Result |
|---|---|---|---|---|
| 1 | UV | Campylobacter | Logdecrease | 26.4 |
| 2 | UV | E.coli O157:H7 | Logdecrease | 19.3 |
| 3 | UV | Rotavirus | Logdecrease | 3.1 |
| 4 | UV | Norovirus | Logdecrease | 3.2 |
| 5 | UV | Cryptosporidium | Logdecrease | 8.8 |
| 6 | UV | Giardia | Logdecrease | 5.0 |
| 7 | Ozonization | Campylobacter | Logdecrease | 0 |
| 8 | Ozonization | E.coli O157:H7 | Logdecrease | 0 |
| 9 | Ozonization | Rotavirus | Logdecrease | 0 |
| 10 | Ozonization | Norovirus | Logdecrease | 0 |
| 11 | Ozonization | Cryptosporidium | Logdecrease | 2 |
| 12 | Ozonization | Giardia | Logdecrease | 2 |
Calculations
Cut the data saved to the previous ovariable by chosen disinfection methods. The default choice includes UV and Ozonization. The creation of the ovariable with the choices can be found on page Drinking water treatment efficiency
