background: the chemical quality of water used for dialysis fluid is a vital factor in the overall care received by dialysis patients. therefore, water used for this purpose should be treated with advanced methods before use for dialysis. the objective of this study was to assess the efficiency of reverse osmosis systems to improve water quality used for dialysis fluid. methods: in this descrip...

background: groundwater resources in arid and semi arid regions are very important. groundwater is contaminated by agricultural, industrial and municipal activity which as a result reduces its quality. investigating of the chemical quality of the groundwater is emphasized to identify pollutant environmental impacts associated with incorrect waste disposal practice. this research investigated th...

Kosovo has limited natural water resources which should be well managed. This is recently realised through quantitative and qualitative monitoring of both surface and groundwater and by characterizing their quality according to their destination. In this paper, the Water Quality Index (WQI) developed by the Canadian Council of Environment Ministers (CCME WQI) was applied to evaluate the groundw...

globally, irrigated agriculture is the largest extractor and the most frequent consumer of groundwater resources, with important groundwater-dependent and largely spread agro-economies. quality of irrigation water is one of the key factors which have either direct or indirect impact on plant growth, soil and water management practices and plant yields. this work aims at highlighting the importa...

Abstract Background and purpose: According to the reported problems in area of the inappropriateness of water quality which used for washing and staining of car apparatuses in a car factory, this research was carried out for identification of physical, chemical, and microbiological characteristics of the consumed water in Babol car factory, Iran. Materials and Methods: Physical and chemical par...

This paper presents a procedure for standard application of hydrologic ⁄water quality models. To date, most hydrologic ⁄water quality modeling projects and studies have not utilized formal protocols, but rather have employed ad hoc approaches. The procedure proposed is an adaptation and extension of steps identified from relevant literature including guidance provided by the U.S. Environmental ...

Target 7C of the Millennium Development Goals is to "halve, by 2015, the proportion of people without sustainable access to safe drinking water and basic sanitation". However, the corresponding indicator measures the "proportion of population using an improved drinking water source". This raises the question of whether "safe" and "improved" can be used interchangeably. This paper tests this hyp...

Evaluation of surface water quality is a complex process undertakingmultiple parameters. Converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.The main aim of this study is to plan effective water resources management system forKarun River by combination of CCMEWQI and Geographic Information System ...
