Drinking water in Cuba and seawater desalination

The lack of drinking water has become a problem at world level because, in many places, supplies are very limited and, in other places, their reserves have been drained. At the present time there are estimated to be around two thousand million people that don't have drinking water for several reasons, such as drought, contamination and the presence of saline waters not suitable for human ...

Effects of drinking desalinated seawater on cell viability and proliferation

Desalination of seawater is becoming an important means to address the increasing scarcity of freshwater resources in the world. Seawater has been used as drinking water in the health, food, and medical fields and various beneficial effects have been suggested, although not confirmed. Given the presence of 63 minerals and trace elements in drinking desalinated seawater (63 DSW), we evaluated ...

Drinking Water Sources, Sanitation and Safeguarding Desalination: a critical element of water solutions for the 21st century

In the face of climate change and the water needs from a growing world population, the use of seawater or brackish water through desalination has increased in importance. The energy efficiency and production costs for desalination plants have been markedly improved. Recent techniques have made it possible to acquire reasonably cheap desalinated water from plants that are fully powered from wind ...

Status and prospects of nuclear desalination

Recent statistics show that currently 2.3 billion people live in water-stressed areas and among them 1.7 billion live in water-scarce areas. In the light of this, the Millennium Declaration by the UN General Assembly in 2000 has set up a target to halve, by the year 2015, the world population who are unable to reach, or to afford, safe drinking water. Better water conservation, water management, ...

Indirect economic impacts in water supplies augmented with desalinated water

Several goals can be considered when optimizing blends from multiple water resources for urban water supplies. Concentration-response relationships from the literature indicate that a changed water quality can cause impacts on health, lifetime of consumer goods and use of water additives like softeners. This paper describes potential economic consequences of diluting Copenhagen's drinking water ...

Overview of seawater desalination status and challenges

Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...
