fuzzy water quality index (fwqi) was applied in order to assess the degree of drinking water resources in yazd province, iran. thisstudy has also offered the creation of a new fuzzy water quality index (fwqi) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...

The Johns Hopkins Hospital in 1999 began to evaluate the safety and efficacy of chlorine dioxide for Legionella control in a potable water system in an acute care hospital environment. The evaluation includes chlorine dioxide, its by-products and their impact on Legionella and pathogenic bacteria, biofilm, medical and laboratory filtration systems, corrosion rates and the environment. The appli...

Recently, Fielding and Roiko found that information provision affects knowledge of and support for potable recycled water. However, recent cultural-sociological insights suggest that such effects are not universal. A re-analysis of the original data reveals the relevance of cultural predispositions: significant effects only exist in specific subgroups of the population. Only those who are comfo...

Water is a prime natural resource and physiological necessity to mankind. Therefore, drinking water must not carry harmful chemicals as well biological contaminants for the well-being human health. Some of like Fluoride, Iron, Arsenic, Cadmium, Chromium, Lead, selenium, Nitrate in may produce serious changes when exist beyond permissible concentration.
 
 The Aim study was create spat...

In the absence of recycling, water represents over 90% of the life-support consumables for a manned spacecraft. In addition, over 90% of the waste water generated can be classified as moderately or slightly contaminated (e.g. shower water, condensate from the air-conditioning system, etc.). The ability to recover potable water from moderately contaminated waste water hence enables significant s...

Over a Period of three months (summer), 108 samples of water collected from four hospitals in Te-hran. They were taken from numerous potable and non-potable water, including main supply cis-terns, calorifiers, hot and cold tap water, shower, cooling tower and drain of air condition system. Culturing of concentrated and non-concentrated water samples on Buffered Charcoal Yeast Extract (BCYE) Aga...

–Abundant as it may seem, in Nigeria, access to clean and potable water is a great challenge. Hence, the reason the physiochemical properties of the groundwater in Agbowo and Ajibode communities in Oyo State, Southwestern Nigeria was analyzed. Water samples were collected from fifteen shallow wells, with varying depths. The water quality parameters were analyzed in accordance to standard method...
