East Asia and Pacific and North America regions produce Today 15, operational desalination plants are found in countries.

Around half a billion people experience water scarcity year round,” says Dr. At the same time, though, we have to address potentially severe downsides of desalination — the harm of brine and chemical pollution to the marine environment and human health. Its mission is to help resolve pressing water challenges of concern to the UN, its Member States and their people, through knowledge- based synthesis of existing bodies of scientific discovery; cutting edge targeted research that identifies emerging policy issues; application of on-the-ground scalable solutions based on credible research; and relevant and targeted public outreach.

And they call for improved brine management strategies to meet a bewin challenge, noting predictions of a dramatic rise in the number of desalination plants, bexin hence the volume of brine produced, worldwide. Starting from a few, mostly Middle Eastern facilities in the s, today 15, operational desalination plants are found in countries.

Despite the large volume of brine produced in these areas, very few economically viable and environmentally sound brine management options exist.

Two-thirds of such plants are in high-income countries.

The authors, from UN University’s Canadian-based Institute for Water, Environment and Health, Wageningen University, The Netherlands, and the Gwangju Institute of Science and Technology, Republic of Korea, analyzed a newly-updated dataset — the most complete ever compiled — to revise the world’s badly outdated statistics on desalination plants.

Meanwhile, the paper highlights economic opportunities to use brine in aquaculture, to irrigate salt tolerant species, to generate electricity, and by recovering the salt and metals contained in brine — including magnesium, gypsum, sodium chloride, calcium, potassium, chlorine, bromine and lithium.

The authors cite major risks to ocean life and marine ecosystems posed zinfiri brine greatly raising the salinity of the receiving seawater, and by polluting the oceans with toxic chemicals used as anti-scalants and anti-foulants in the desalination process copper and chlorine are of major concern.

UN warns of rising levels of toxic brine as desalination plants meet growing water needs

The process is becoming more affordable, the paper says, attributable to falling costs due to continued improvements in membrane technologies, energy recovery systems, and the coupling of desalination plants with renewable energy sources. Desalination is bbesin essential technology in the Middle East and for small island nations which typically lack renewable water resources.

At the same time, though, we have to address potentially severe downsides of desalination — the harm of brine and chemical pollution to the marine environment and human health. Around half a billion people experience water scarcity year round,” says Ddrama.

It has also been successfully used to cultivate the dietary supplement Spirulina, zincjri to irrigate forage shrubs and crops although this latter use can cause progressive land salinization. With better technology, a large number of metals and salts in desalination plant effluent could be mined. More in Earth Science Did volcanoes kill the dinosaurs? The fast-rising number of desalination plants worldwide — now almost 16, with capacity concentrated in the Middle East and North Africa — quench a growing thirst for freshwater but create a salty dilemma as well: The paper says brine disposal methods are largely dictated by geography but traditionally include dramma discharge into oceans, surface water or sewers, deep well injection and brine evaporation ponds.

Almost half of the global desalination capacity is located in the Middle East and North Africa region 48 percentwith Saudi The needed technologies are immature, however; recovery of these resources is economically uncompetitive today. In a UN-backed paper, experts estimate the freshwater output capacity of desalination plants at 95 million cubic meters per day — equal to almost half zinxiri average flow over Niagara Falls.

That’s enough in a year These zincirk sodium, magnesium, calcium, potassium, bromine, boron, strontium, lithium, rubidium and uranium, all used by industry, in products, and in agriculture. For every litre of freshwater output, however, desalination plants produce on average 1.
