Desalination plants on Karachi coast to help overcome water shortage – Pakistan

The desalination plants will be used to provide water to the residents of the old city areas and the neighbourhood of the Defence Housing Authority (DHA) near the seaside. The proposed desalination plants will each supply five million gallons daily (MGD) water to the city.

The KWSB has proposed three locations for setting up the desalination plant in the city i.e. Ibrahim Hyderi, near Ayesha Mosque in DHA Phase-7, and near Village Restaurant at Sea View.

Los Pelambres’ desalination plant 86% complete – Salamanca, Chile

Construction is slated to be finished by the end of the year, and the plant is expected to provide 400 litres per second of industrial-quality desalinated water.

According to the miner, this project will turn Los Pelambres into the first mining operation that uses seawater to produce copper in Chile’s central region, and it will benefit both the existing and expanded operation in cases of prolonged or severe drought.

Thames Water’s £250million desalination plant is turned OFF even though it is supposed to supply drinking water to 400,000 London homes every day during droughts – London, UK

The plant, which was opened by the Duke of Edinburgh in 2010, is the only one in the UK designed to turn salty seawater into fresh water. 

It was originally marketed as being able to offer an additional 150 million litres of water a day – but this has now been revised down by a third to 100 million.

It said that regardless of the plant’s current operational status, short term hosepipe bans would still be required to curb water usage.

75 water desalination plants operating across Iran – Tehran

Iran’s National Water and Wastewater Engineering Company is operating and constructing 95 water desalination plants with a total capacity of 634,000 cubic meters per day across the country, of which 75 plants are currently operational, according to an official with the company.

“Based on the government’s plan to develop the capacity of water desalination plants and to expand the use of these facilities, over the next four years, at least 400,000 cubic meters per day will be added to the capacity of the country’s water desalination plants,” Golrizan said.

Plans to increase desalination plant capacity to ensure supply – Jersey

The plant can currently produce just over ten million litres of drinking water a day – roughly half of the Island’s average daily usage. The company now plans to increase capacity by five million litres per day – enough to fill two Olympic-sized swimming pools – to meet a projected rise in demand caused by climate change and a growing population.

Commenting on the plans to use the plant this summer, he said: ‘We need to pressure-test the system because we have had some assemblies changed. So we will take advantage of this to run some water into Val de la Mare.

Codelco will construct $1 billion desalinization plant – Santiago, Chile, South America

The desalination plant will have an initial capacity of 840 liters per second and the potential to expand to 1,956 l/s and will be located near the northern town of Tocopilla.

The company plans to reduce fresh water consumption by 60% by reusing water from tailings deposits, getting sea water from the desalination plant and improving the efficiency of its operating processes.

AFRICA: desalination now at the heart of water supply strategies – South Africa

According to the United Nations (UN), the rate of people with safe access to drinking water has only increased from 17.9% to 23.7% in sub-Saharan Africa since 2000.

This is the case of the Agadir desalination plant (in Morocco), currently under construction, with an expected capacity of 275,000 m 3 per day. Part of the treated water, ie 125,000 m 3 per day, will supply an irrigation system in the plain of Chtouka, in the center-west of Morocco.

… a manufacturer of canned fish, has set up two private seawater desalination plants in Laaiplek and Amawandle Pelagic, on the west coast of the country, with a combined capacity of 624 m 3 per day.

The first phase of the project should make it possible to obtain a capacity of 100,000 m 3 per day. The capacity of the installation will then be increased to 200,000 m 3per day in the second phase.

Scientists created a mobile desalination unit that can convert salt water into drinking water without filters – MIT, USA

Rather than filtering water, the ICP method uses an electrical field to apply to membranes above and below a water channel.

Negatively and positively charged particles, like viruses, salt molecules, and bacteria, are repelled by the membranes as they pass by. The charged particles are channeled into an additional stream of water, which is released later.

Israel launches plan to restore and develop southern Jordan River – Jordan

The plan aims to increase the amount of water and cut pollution in the Israeli section of the river, with the establishment of a new desalination facility that will treat the polluted and salty water.

Today, only about 70 million cubic meters of water flow in the southern course per year, mostly polluted and salty due to the activity of a nearby sewage treatment plant.
