So far, the prototype system has worked in the lab for at least a week without accumulating salt. The next challenge is to scale it to something more practical, but…

Researchers at MIT and in China have improved the old-fashioned solar still with a new inexpensive device that harnesses the sun to remove salt from water.

The key to this new technique is black paint and polyurethane with 2.5-millimeter holes drilled in it. The idea is that warmer water above the insulating medium causes the salt to concentrate in the cooler water beneath the insulator allowing efficient vaporization of the water.  As the water evaporates, it causes the salt concentration at the top to rise, which then sinks due to the higher density and lower-concentration salt water rises to the top to evaporate.

China’s 1st nuclear steam project to turn seawater into clean energy – China

China has started construction of its first nuclear-powered steam supply project for industrial purpose to utilize heat generated by the nuclear power to convert desalinated sea water into clean, stable and efficient industrial steam and reduce energy consumption and carbon emissions.

According to CNNC, its Tianwan nuclear-powered project with a total investment of $108.4 million and construction period of 24 months, will be fully operational by the end of 2023.

New desalination plants, power stations, and pumping stations will also be built under the project. 


Beijing looking toward Maldives, Horn of Africa – China

China and the Maldives have stepped up cooperation across a wide range of areas following a meeting between State Councilor and Foreign Minister Wang Yi and Maldivian Foreign Minister Abdulla Shahid in the Maldives capital, Male, on Saturday.

During their talks, the two foreign ministers agreed to strengthen bilateral and multilateral cooperation and communication, jointly uphold the purposes and principles of the UN Charter, oppose interference in the domestic affairs of other countries and safeguard international fairness and justice.

They witnessed the signing of a number of agreements on bilateral cooperation including the right to visit each other’s countries without first obtaining a visa. Under the agreement, Chinese and Maldivian citizens will be entitled to a 30-day visa upon arrival in the other country. The Maldives is a very popular tourist destination for Chinese people.


HK desalination plant expected to be completed on schedule – Hong kong

The construction of a desalination plant in Hong Kong designed to expand water supplies in the special administrative region is expected to finish and put into use in 2023, the project engineers said on Tuesday.

The Tseung Kwan O desalination plant, built with a water production capacity of 135,000 cubic metres per day, can meet 5 percent of Hong Kong’s current fresh water demand, said Lee Kwun-chung, chief engineer from the Water Supplies Department of the Hong Kong SAR.

After its entry into service, it will be the first desalination plant using seawater reverse osmosis technology in the city, the most advanced and efficient technology for the production of drinking water from seawater, Lee said.


China issues 5-year action plan for seawater desalination – China

China has issued an action plan for seawater desalination utilization development over the next five years, according to China Science Daily on Friday.

The action plan, jointly issued by the National Development and Reform Commission (NDRC) and the Ministry of Natural Resources, is expected to promote the large-scale utilization of seawater desalination and ensure the safety of water resources in coastal areas.

China’s seawater desalination scale will exceed 2.9 million tonnes per day by 2025, an increase of more than 1.25 million tonnes per day, according to the action plan.


China makes desalination push to ease water scarcity – China

China will invest in new desalination plants over the 2021-2025 period and raise capacity to 2.9 million tonnes a day in a bid to boost water supplies, the country’s state planning agency said in a new “five-year plan” for the sector.

As much as 1.25 million tonnes per day of new capacity will be commissioned over the period, including 1.05 million tonnes in coastal cities and 200,000 tonnes in “island regions,” the National Development and Reform Commission said on Wednesday.

Demonstration seawater desalination projects will be built in the provinces of Liaoning, Hebei, Shandong and Zhejiang as well as the city of Tianjin.


Large desalination project starts running in north China – China

SHIJIAZHUANG, Dec. 16 (Xinhua) — A large desalination project, capable of producing 10,000 tonnes of freshwater from seawater per day, started operations on Wednesday in Tangshan City, north China’s Hebei Province.

The thermal-membrane hybrid seawater desalination project, operated by Shougang Jingtang United Iron & Steel Co., Ltd., is hailed as an industrial breakthrough in the country’s steel sector, a big consumer of water.

The new project combines the “thermal” and “membrane” approaches in seawater desalination: the former uses waste heat produced by factories to distill seawater, while the latter relies on ultrafiltration and reverse osmosis membranes, similar to household water purifiers, said Zhang Bo with the company’s energy and environmental protection department.


Senate legislation would expand COVID-19 projects with Israel to lessen dependence on China – Israel

The Senate has introduced legislation to enhance partnerships between American and Israeli companies on COVID-19 projects, thus lessening U.S. dependence on China for life-saving medications and treatments.

The bipartisan legislation was introduced on Wednesday as Secretary of State Mike Pompeo, on a whirlwind eight-hour visit to Israel, criticized China while praising Israel.

“You’re a great partner,” Pompeo said in an appearance with Prime Minister Benjamin Netanyahu before their meeting in Jerusalem. “You share your information, unlike some other countries that try and obfuscate and hide information. And we’ll talk about that country, too.”


US said to question China’s role in bid to construct Israeli desalination plant – United States

US officials have questioned a China-tied company’s bid to construct a new desalination plant in Israel and have expressed concerns over the possibility of it winning the tender, Axios reported Saturday.

Hutchison Water International is one of two companies to have reached the final stage of the tender to build the Sorek B plant, set to be the largest desalination facility in the world, alongside IDE Technologies.

Hutchison is owned by Hong Kong-based holding company CK Hutchison Holdings.
