New and improved methods are needed to disinfect pathogens in treated wastewater, especially highly resistant ones like Cryptosporidium parvum oocysts. In addition, new and improved methods are needed to detect pathogens and indicators for them in wastewater in order to monitor the efficacy of disinfection and other waste water treatment processes. Spores of the anaerobic bacterium Clostridium ...

Water supply is a critical issue in the Middle East, particularly in the West Bank and Gaza Strip (Palestine). Water resources are scarce due to the arid climate and the population growth while water resources management and development is complicated by the ongoing Israeli occupation. There is a critical lack of sanitation in the West Bank. Only 45% of the Palestinian population is connected t...

The use of non-conventional water resources including treated municipal wastewater has been increasing in the Mediterranean regions over the last decades to cope with water shortages and uneven rainfalls due to climate change. The aim of this paper is to present the first results from two years of experimental field activities carried out in two different demo-places in Southern Italy: the muni...

The physicochemical conditions of high-rate algal ponds were responsible for a more than 97% reduction in the infectivity of Cryptosporidium parvum oocysts in neonatal mice. The use of semipermeable bags of cellulose showed that pH, ammonia, and/or light seems to be a major factor for the inactivation of oocysts in wastewater, supporting the importance of alga-based systems for safer reuse of t...

Great attention has been paid to the potential of wastewater irrigation as a sustainable water source, particularly due to water scarcity and water pollution issues. However, few studies have focused on its adverse effects and on the health risks it may pose. In this study, the physicochemical properties of soils and plants irrigated with rural domestic wastewater and associated microbiological...

Toxicity of four types of industrial wastewater, treated by Fenton’s reagent, was analyzed. Toxicity was measured using bioluminescent bacteria Vibrio fischeri NRRL B-11177. Application of Fenton’s reagent was a efficient method for treatment of this wastewater. Nevertheless, high efficiency of organic components degradation was not always followed by reduction of toxicity to a very low level. ...
