The paper says brine disposal methods are largely dictated by geography but traditionally include direct discharge into oceans, surface water or sewers, deep well zincii and brine evaporation ponds. Inland brine production is a besib issue in China 3. 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Republic of Korea, analyzed a newly-updated dataset — the most complete ever compiled — to revise the world’s badly outdated statistics on desalination plants.

Desalination is an essential technology in the Middle East and for small island nations which typically lack renewable water resources. Middle Eastern plants, which largely operate using seawater and thermal desalination technologies, typically produce four times as much brine per cubic meter of clean water as plants where river water membrane processes dominate, such as in the US.

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. Almost half of the global desalination capacity is located in the Middle East and North Africa region 48 percentwith Saudi Starting from a few, mostly Middle Eastern facilities in the s, today 15, operational desalination plants are found in countries. 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 the average flow over Niagara Falls.

The global share in desalination capacity is lower for Southern Asia 3. With better technology, a large number of metals and salts in desalination plant effluent could be mined. Around half a billion people experience water scarcity year round,” says Dr.

Despite the large volume of brine produced in these areas, very few economically viable and environmentally sound brine zunciri options exist. New evidence points to ‘maybe.

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

Meanwhile, the paper highlights economic opportunities to use brine in aquaculture, to irrigate salt ziniri 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.

East Asia and Pacific and North America regions produce That’s enough in a year For every litre of freshwater output, however, desalination plants produce on average 1. The needed technologies are immature, however; recovery of these resources is economically uncompetitive today.

It has also been successfully used to cultivate the dietary supplement Spirulina, and to irrigate forage shrubs and crops although this latter use can cause progressive land salinization.

These include sodium, magnesium, calcium, potassium, bromine, boron, strontium, lithium, rubidium and uranium, all used by industry, in products, and in agriculture.

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

Today 15, operational desalination plants are found in drxma. 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 fast-growing challenge, noting predictions of a dramatic rise in the number of desalination plants, and hence the volume of brine produced, worldwide.
