Solar disinfection of wild Salmonella sp. in natural water with a 18 L CPC photoreactor: Detrimental effect of non-sterile storage of treated water

| description | ► In this study a 18 L solar CPC reactor was successful to inactivate wild
Salmonella sp. bacteria present in Burkina Faso real raw waters. ► Inactivated wild
Salmonella sp. did not show regrowth after 72
h of dark sterile storage. ► Addition of H
2O
2 did not prevent bacterial regrowth during post-irradiation storage in non-sterile containers.
For the first time solar disinfection of liters of water containing wild
Salmonella sp. and total coliforms was carried out in a compound parabolic collector (CPC) photoreactor at temperatures of almost 50
°C. Using surface water with high turbidity, this treatment was efficient in completely inactivating
Salmonella sp. without regrowth during the subsequent 72
h of dark sterile storage. However if the solar treated water is poured in a non- sterile container, bacteria regrowth occurs even if 10
mg
L
−1 of H
2O
2 is added before the storage. On the other hand, 30
mg
L
−1 of H
2O
2 added when the irradiation started was completely depleted within 2 h and did not prevent bacterial regrowth during post-irradiation storage in non-sterile containers, demonstrating that storage of large volumes of water treated by solar irradiation was not optimal. Finally, total coliforms (
Escherichia coli included) showed a far higher sensitivity than
Salmonella sp. and demonstrated to be an inappropriate indicator for monitoring bacterial contamination in water during solar disinfection processes. |
