background the chemical and physical quality of water used for dialysis fluid is a vital factor in the patients overall care who receive dialysis. therefore, the water used for this purpose must be treated with advanced methods before being used for dialysis. conclusions the evaluation of hemodialysis water quality showed that these hospitals were not significantly polluted and the water qualit...

water quality is a most important factor in areas facing water crisis the survival of which is based upon it. in a determination of water value the factors that should be attended to are: the given volume, specified quality(preservation value), as well as the specific time and place.valuation of water in iran is dependent on types of exploited water resources which include: human consumption(qu...

rivers can be contaminated with different pollutants such as trout farms. evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. in current work, the effect of constructed trout farms near the deinachal river on some physicochemical properties namely chemical oxygen demand (cod), biological oxygen demand (bod5), dissolved oxygen ...

background: although experiments on water quality are time consuming and expensive, models are often employed as supplement to simulate water quality. artificial neural network (ann) is an efficient tool in hydrologic studies, yet it cannot predetermine its results in the forms of maps and geo-referenced data. methods: in this study, ann was applied to simulate groundwater quality and geographi...

introduction: the increasing of population and limited drinking water resources has enhanced the necessity of using bottled water. many people are now using bottled water because they believe it is a healthful alternative beverage to soft drinks or other bottled beverages. therefore, the bottled water industry has grown immensely during the past decades. this descriptive cross-sectional study h...

the application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. in this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. the five treatments were control (withoutamendment), municipal solid waste compost (mc), vermicompost...
