Abstract The use of poorly treated water in hemodialysis centers may lead to fungal contamination, which poses a serious threat to immunologically debilitated hemodialysis patients. This study aimed to isolate and identify yeast species in the water of a Brazilian hemodialysis center by using classic microbiological techniques and Raman spectroscopy. For 12 months, a total of 288 water samples were collected from different points of the hemodialysis treatment distribution center. One hundred and forty-six yeast species were isolated and identified in the samples that tested positive for the presence of yeasts such as Candida parapsilosis (100 isolates, or 68.50%), C. guilliermondii (17 isolates, or 11.65%), Rhodotorula mucilaginosa (23 isolates, or 15.75%), R. glutinis (three isolates, or 2.05%), and Trichosporon inkin (three isolates, or 2.05%). Yeast susceptibility to the antifungal fluconazole was also assayed. Only two C. guilliermondii isolates were resistant to fluconazole: the minimal inhibitory concentrations were higher than 64 μg/mL. The different yeast species present in the water of a Brazilian hemodialysis center call for more effective water disinfection procedures in this unit. Raman spectroscopy is an excellent tool to identify yeast species and is potentially applicable in routine water monitoring in hemodialysis units.

Abstract Solar disinfection, as a low carbon technology, is a sustainable and cost-effective water treatment method, which makes it more likely to be implemented in developing countries. It has been proven that ultraviolet light radiation is effective against pathogens and microorganisms. The aim of this paper is to evaluate the performance of solar disinfection apparatus that is equipped with Wood’s glass and a Fresnel lens. Wood’s glass is a band-pass filter that allows ultraviolet light to go through and blocks most of the remaining spectrum including infrared. This serves a dual purpose. It lets through the part that inactivates pathogens and microorganisms (ultraviolet) and blocks the part that helps the growth of bacteria (infrared). Experimental setup is designed to investigate the effect of Wood’s glass with and without a Fresnel lens on the solar disinfection process. The investigation is done on a batch-based system and on a novel instantaneous water disinfection system. Results of water disinfection process were recorded for each set of experiments taking into considerations vital parameters, such as solar radiation, solar ultraviolet light intensity and water temperature. The results of these experiments showed effective water disinfection up to 85% pathogens removal by the use of daily available solar radiation.
