This report presents a novel Advanced Multi-Effect Distillation (AMED) method that can enable the production of substantial quantities of low-cost desalinated water using waste heat from high temperature reactors (HTRs). Conventional MED systems can currently compete with reverse osmosis desalination in areas where energy costs are relatively low, such as the Middle East. Because AMED can perfo...

Background: Continuous expansion of potable water pollution sources is one of the main concerns of water suppliers, therefore measures such as water safety plan (WSP), have been taken into account to control these sources of pollution. The aim of this study was to identify probable risks and threatening hazards to drinking water quality in Lighvan village along with assessment of bank filtratio...

groundwater is the main source of potable water in most areas of mazandaran province, like sari and babol city. thus the safety of groundwater supplies is very important in these regions. unfortunately attention to groundwater quality has remained limited in iran. in recent years, the growth of industry, technology, population, and water use has increased the stress upon both land and water res...

Groundwater is an important source of potable water because it is abundant and readily available in many locations and often requires little or no treatment. In 1995, groundwater accounted for approximately 20% of potable water use in the U.S., and approximately 50% of the U.S. population relied on groundwater for their source of drinking water. In most European countries, groundwater accounts ...

Growing demands for potable water have strained water resources and increased interest in wastewater reclamation for potable reuse. This interest has brought increased attention to endocrine-disrupting chemicals (EDCs) as emerging water contaminants. The effect of EDCs, and in particular natural steroid hormones, on humans is of heightened interest in the study of wastewater reuse in advanced l...

background : microbial monitoring of aquatic sources is essential in the correct management of these vital sources. multiple tube fermentation (mtf) technique is currently used for assessment of the microbial quality of water sources. however, today enzymatic assay has been presented as an alternative approach for detecting indicator bacteria. the purpose of this study was to compare enzymatic ...

Current centralized urban water supply depends largely on energy consumption, creating critical water-energy challenge especially for many rapid growing Asian cities. In this context, harvesting rooftop rainwater for non-potable use has enormous potential to ease the worsening water-energy issue. For this, we propose a geographic information system (GIS)-simulation-based design system (GSBDS) t...
