“…The results of the SODIS experiments were analyzed using the Geeraerd and Van Impe Inactivation Model Fitting Tool (GInaFiT) (14). This model has been used previously for the fitting of solar (1) and photocatalytic disinfection (34,35) studies. The following models were used: loglinear regression (2), log-linear plus tail (13), Weibull model (22), biphasic model (5), and Weibull model (14).…”

Batch solar disinfection (SODIS) inactivation kinetics are reported for suspensions in water of Campylobacter jejuni, Yersinia enterocolitica, enteropathogenic Escherichia coli, Staphylococcus epidermidis, and endospores of Bacillus subtilis, exposed to strong natural sunlight in Spain and Bolivia. The exposure time required for complete inactivation (at least 4-log-unit reduction and below the limit of detection, 17 CFU/ml) under conditions of strong natural sunlight (maximum global irradiance, ϳ1,050 W m ؊2 ؎ 10 W m ؊2 ) was as follows: C. jejuni, 20 min; S. epidermidis, 45 min; enteropathogenic E. coli, 90 min; Y. enterocolitica, 150 min. Following incomplete inactivation of B. subtilis endospores after the first day, reexposure of these samples on the following day found that 4% (standard error, 3%) of the endospores remained viable after a cumulative exposure time of 16 h of strong natural sunlight. SODIS is shown to be effective against the vegetative cells of a number of emerging waterborne pathogens; however, bacterial species which are spore forming may survive this intervention process.

“…It has been proven that solar disinfection is very effective in spores of phytopathogenic fungi, which are responsible for diseases of great incidence in agriculture and hospital distribution systems [64,65]. It is possible to inactivate about 1000 colonies per millilitre of spores of five types of the Fusarium species (F. equiseti, F. verticillioides, F. solani, F. oxysporum, and F. antophilum) with different level in bottle reactor during 1-6 h exposure to natural solar radiation in perfectly sunny day [66].…”

A primary concern of developing countries throughout the world is that of obtaining safe drinking water. Waterborne diseases are still common in developing countries since drinking water sources are contaminated and the conventional rural water treatment plants are often inefficient to produce safe drinking water. This situation in developing countries is a major problem in terms of preventing public health. It is estimated that diarrhea accounted for 99% of the 69 million deaths among children before the age of five. Inadequate operation and maintenance after installations caused by a lack of trained operators, by a treacherous supply of chemicals and spare parts, and by financial problems lead to produce unhealthy drinking water. Since major urban water supplies are also not always capable of maintaining a regular supply of qualitatively good water, the distributed water is often considered unsafe for direct consumption. Treatment of water at the household level (etc. boiling) or purchasing of mineral water for consumption is more real than an exception in urban areas of developing countries. Recently, another small-scale approach using the lethal effect of sunlight has gained importance to sanitary contaminated water. Solar disinfection (SODIS) is one of the simplest methods for providing acceptable quality drinking water and consists of filling transparent containers (plastic bags, plastic bottles or glass bottles) with water and exposing the containers to sunlight for approximately 6 hours. Because of the low cost and easy usage, solar disinfection is commonly used in developing countries in Asia, Africa and South America. The aim of this literature review is to give information about solar disinfection mechanism, to compare the efficiency of solar disinfection on different microorganisms based on the past studies, and to discuss the several applications of solar disinfection in the world.

“…Since then, there have been a large number of research studies reporting the use of photocatalysis to inactivate microorganisms including bacteria (cells (8,9), spores and biofilms (10), viruses (11), protozoa (12), fungi (13) and algae) (14). Photocatalytic disinfection has been reviewed by several researchers including Byrne et al (15), McCullagh et al (16), Malato et al (17) and Robertson et al (18).…”

The lack of clean and safe drinking water is responsible for more deaths than war, terrorism and weapons of mass destruction combined. This suggests contaminated water poses a significant threat to human health and welfare. In addition, standard water disinfection approaches such as sedimentation, filtration, and chemical or biological degradation are not fully capable of destroying emerging contaminants (e.g. pesticides, pharmaceutical waste products) or certain types of bacteria (e.g. Cryptosporidium parvum). Nanomaterials and nanotechnology based devices can potentially be employed to solve the challenges posed by various contaminants and
