Background and Objective: Surface water and underground water quality in countries that facing dehydration have increased the interest of the community to use Household Water Treatment devices. The aim of this study was the evaluation of the quality of drinking water of Household Water Treatment devices and general distribution network in Garmsar, which is under the control of the water safety ...
The main portion of water demands of arid regions like Kashan Plain, Iran supply by groundwater wells. This research was conducted to assess the groundwater quality as well as modelling and mapping groundwater quality in the study area using geosatistics and deterministic techniques. Five water quality parameters, including Electrical Conductivity, Sodium Adsorption Ratio, Total Hardness, ...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
the influence of leachate from open solid waste dumping near salhad stream (abbottabad, pakistan) was investigated to quantify the variations of water quality during august 2007 to april 2008. samples were collected from five different sites located along the salhad stream. two sites were located before the mixing of solid waste leachate with the surface water. one sampling site was of leach...
Introduction: With attention to the existence numerous numbers of industrial towns and them volume of generated wastewater and problems of shortage of water in the Yazd province, therfore the proper wastewater treatment and efficient management of waste water of industrial towns for reuse of them is one of the most important of program for reducing & saving in water consumptio...
The surface water chemistry of Thiruvananthapuram Museum Lake was carried out in the period of February 2013 to January 2014. Correlation study of the parameters and overall CCME WQI (Canadian Council of Ministers of the Environment Water quality Index) was also prepared in the study for the lake water. The parameters analysed are cations such as Ca2+, Na+, Mg2+ and K+ and the anions like PO4-,...

magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
Droughts are natural events and could lead to declining surface water quality of regional basin. Understanding the complex impacts of drought may help authorities to monitor changes in different regional basin and to make appropriate decision on development of a river basin management plan. In this study 20 years annual precipitation time series from 1994-2013 from 7 synoptic weather stations l...
Introduction: Considering the increasing population and the growing need for food and drinking water, it is essential to explore and understand the factors of crop production, especially water resources. Today, the removal of undiluted water from underground water sources has produced qualitative issues, in addition to a few shortcomings. These issues are more significant in arid and semi-arid ...
