based on langelier, corrosion index of water in the distribution system was balanced. shadegan is a city and the capital of shadegan county in khuzestan province, iran. it has an area of 3197 m2 and located 84 km south of ahvaz. water distribution system serves 70,000 people in the city and the total consumed drinking water is 28525 m3per day (3,4).this descriptive, cross sectional study examin...

Preservation of water quality, particularly in areas with inadequate water resources is considered as one of the principles of planning in integrated water management. In Kuhdasht, a region at the west of Iran, groundwater and spring water resources are the major contributors of drinking and irrigation water supply. The aim of this study was to determine the suitability and mapping of springs a...

The Danube is an international river passing partly through Serbia. The protection of the environment and sustainable use of water resources is a primary task that implies constant monitoring of the quality status and evaluation of ecochemical status of the water in the Danube basin. The investigation includes calculation of all-inclusive water quality by the Serbian water quality index (SWQI) ...

Chapter 1 introduced the index and indicator concept and outlined a number of microorganisms (and groups of microorganisms) that have been adopted in the quest to determine whether or not drinking water is microbiologically safe to drink. This chapter examines the range of both microbial and non-microbial parameters and briefly outlines their uses and applications. It is intended to act as an i...

BACKGROUND The bacterial and chemical contamination of dialysate fluids are important problems in haemodialysis therapy and may be caused by the water used for dialysate preparation. METHODS We performed a survey of the microbiological and chemical quality of the water used in seven dialysis wards. Special attention was paid to the effects of each water treatment step, for example ion exchang...

Generally, wavelets are purposefully crafted to have specific properties that make them useful for signal processing. In recent years, wavelet analysis have commonly been used instead of Fourier analysis. This is a new approach for evaluation of water quality parameters. This study determined water quality parameters and effects on water quality in Gölcük, Turkey. A 13-month data series was com...

todays, the world development is facing serious water quality issues. since protect of water quality and ecosystem healthy is an important aspect of ecohydrology. the present research aimed to analyze the temporal trends of water quality parameters of mashin zard river station in order to planning long term management approaches. in this research, trend of some significant factors of water qual...

human activities in the recent years have considerably increased the rate of water pollution in many regions of the world. in this case study, the main sources of wastewater discharging into the gargar river were identified. using river and point source flow rates and water quality parameters measured along the river, the river water quality was simulated using a commonly used, one-dimensional ...
