Solar disinfection of turbid hygiene waters in Lexington, KY, USA

Abstract Solar disinfection (SODIS) could be a key to providing clean, hygiene water for birthing uses, but the recommended climate zone is limited, microbial indicators are related gastrointestinal illness and not wound infections. SODIS feasibility was investigated remove Escherichia coli from turbid at temperatures less than 50 °C in Lexington, KY. Increasing turbidity 0 200 NTU decreased E. inactivation 5 1 log. With same experimental protocol, more 4-log of Staphylococcus aureus epidermidis (common human-skin microorganisms serious post-partum infections both mother child) achieved different levels with maximum, in-bottle temperature 49.2 after 5.5 h. The thermal bacterial assessed without UV radiation 37 47 °C. Skin bacteria were inactivated completely 9.5 h °C, only 58% removal happened thermo-tolerant coli. These results suggest that application may expanded geographically treat purposes. However, as also capable causing infections, required produce safe by outside latitudes.
