Solar Disinfection Using Zero Valent Iron for Inactivation of Escherichia coli and Total Coliforms in Water Using a Raceway Reactor

Water, Год журнала: 2023, Номер 15(18), С. 3211 - 3211

Опубликована: Сен. 9, 2023

Contamination from microorganisms is one of the gravest types water pollution. In 2022, there were 842,000 new cases gastrointestinal diseases worldwide. The aim this study was to size, construct, and evaluate a Raceway reactor (28 L total capacity) as laboratory-scale solar disinfection system for inactivation Escherichia coli coliforms in water, using Zero Valent Iron (ZVI). For purpose, sample E. contaminated potable treated with steel wool source ZVI irradiation. Using 23 factorial design four central points 12 trials, following investigated: effect Fe0 dose (0.6–1.8 g L−1); it should be noted that both natural drinking waters area have iron concentrations less than 0.1 mg L−1. Depth tests carried out at different levels (5, 7 9 cm) duration six hours. Therefore, concluded reactor/ZVI effective >2419.6 MPN/100 mL, reaching 99.96% cases; also cost-effective treatment due its inexpensive inputs.
