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 ...

Water Reuse’s Role in Water-Scarce South Africa
The Development Bank of South Africa is among the voices calling for increased investment in water reuse technology According to estimates from the United Nations, 1.8 billion people around the world will live with absolute water scarcity by 2050, meaning they will have access to less than 500m3 per capita in water supplies. Today, Sub-Saharan Africa has more water-stressed countries than any ...

Consumer perception of water quality, abundance, and cost: comparison of drinking water source, attitudes, and preference
Public attitudes about drinking water quality, fresh water availability, water spending, and suitable uses for recycled water were determined with a survey administered to respondents in the Gulf Cooperation Council (GCC), North America, and Europe. Statistically significant differences in perception were identified as a function of respondent’s country of residence. Among the findings are a ...

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 ...

Water Quality Standards as per BIS (IS 10500:1983 )
Water and it's necessary The world having almost 70 % water and its we can able to drinking water is 1% only. Thats why desalination of water is very important to cover all human to drink. We can not live without drinking water. Atleast 5-6 liter per day need to drink for avarage man. Recommended Guidelines for Physical and Chemical water quality standards as per BIS ...

Acceptance of water alternatives in Australia – 2009
In a nationally representative study with a sample size of 1495, Australian residents were asked about their attitudes to recycled and desalinated water. Specifically, they were asked to state how likely they would be to use these sources of water for 14 purposes. Recycled water was found to have a higher stated likelihood of being used for watering gardens (compared to desalinated water). No ...

Seawater desalination and serum magnesium concentrations in Israel
With increasing shortage of fresh water globally, more countries are consuming desalinated seawater (DSW). In Israel >50% of drinking water is now derived from DSW. Desalination removes magnesium, and hypomagnesaemia has been associated with increased cardiac morbidity and mortality. Presently the impact of consuming DSW on body magnesium status has not been established. We quantified ...

Pros and Cons of Seawater Desalination using Reverse Osmosis for Drinking Water
Seawater desalination will undeniably be the future of drinking water production for coastal communities and island nations in current times of water scarcity. It is already used quite heavily in a few countries. Saudi Arabia, the United Arab Emirates, and the United States are the top three desalination producers of drinking water by capacity in the world followed by Australia, China, and ...

REvivED Project
REvivED water project aims to contribute to overcoming the drinking water challenge via novel desalination. The goal is to produce safe, affordable and cost-competitive drinking water with significantly reduced energy consumption compared to state-of-the-art Reverse Osmosis (RO) desalination technology. The project comprises several systems and applications with 12 pilots in total, ranging from ...

Effect of blending ratio on the formation of bromoform and bromate in blended water samples disinfected with chlorine or ozone
This study was carried out to assess the potential formation of bromoform and bromate in drinking water samples prepared by blending desalinated and brackish ground water when disinfected by chlorination or ozonation methods. The levels of bromoform and bromate were determined under various treatment conditions including blending ratios, disinfectant dosage, temperature, and reaction time. ...

MIDES Project
The production of low-cost drinking water from sustainable resources is still the biggest challenge facing the world. Reverse Osmosis (RO) desalination is broadly used to produce drinking water. MIDES project introduces the Microbial Desalination Cell (MDC) as a pre-treatment for RO. The goal is to dramatically decrease the energy required for the drinking water production, to archive a high ...

Seawater desalination for methanex
Methanex has a large methanol production facility in Punta Arenas, Chile. In this region of the world, fresh water is not available, and the facility requires seawater desalination to provide drinking water and process water. When the facility underwent renovation and expansion of their facilities, Aqua-Chem ICD provided a total of five (5) new Once through Multi-stage Flash plants. The Problem ...

Comparison of commercial analytical techniques for measuring chlorine dioxide in urban desalinated drinking water
Most drinking water industries are closely examining options to maintain a certain level of disinfectant residual through the entire distribution system. Chlorine dioxide is one of the promising disinfectants that is usually used as a secondary disinfectant, whereas the selection of the proper monitoring analytical technique to ensure disinfection and regulatory compliance has been debated ...

Extensive Aquifer Discovered Under Atlantic Seabed
The deposit, which contains brackish water, could be a source of easily desalinated drinking water The Atlantic Ocean is not the first place one would think of looking for fresh water, but that is exactly where Columbia University Lamont-Doherty Earth Observatory researchers have found it — and not just a little bit. The newly discovered aquifer is embedded in porous sediments beneath a ...

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 ...

Desalination in the Caribbean
Islands have long relied on the process to supplement natural water supplies More than 7,000 islands of the Caribbean Archipelago are scattered over a million-square-mile area between North and South America. Some smaller islands are naturally dry, but some volcanic islands — like Grenada and St. Lucia — are well forested and provide significant water catchment to support spring ...

Desalination in the Caribbean
On Aruba and some other Caribbean islands, a lack of rainfall makes desalination a logical choice for ensuring potable water supplies. Islands have long relied on the process to supplement natural water supplies More than 7,000 islands of the Caribbean Archipelago are scattered over a million-square-mile area between North and South America. Some smaller islands are naturally dry, but ...
