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.

System achieves new level of efficiency in harnessing sunlight to make fresh potable water from seawater – Cambridge

A completely passive solar-powered desalination system developed by researchers at MIT and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area.

Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source.

The system uses multiple layers of flat solar evaporators and condensers, lined up in a vertical array and topped with transparent aerogel insulation. It is described in a paper appearing today in the journal Energy and Environmental Science, authored by MIT doctoral students Lenan Zhang and Lin Zhao, postdoc Zhenyuan Xu, professor of mechanical engineering and department head Evelyn Wang, and eight others at MIT and at Shanghai Jiao Tong University in China.

New solar-powered system makes desalination ecofriendly – America

A completely passive solar-powered desalination system developed by researchers at Massachusetts Institute of Technology (MIT) and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square metre of solar collecting area. 

Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source, said MIT doctoral students in a paper appearing in the journal ‘Energy and Environmental Science’.

The key to the system’s efficiency lies in the way it uses each of the multiple stages to desalinate the water. At each stage, heat released by the previous stage is harnessed instead of wasted. In this way, the team’s demonstration device can achieve an overall efficiency of 385 percent in converting the energy of sunlight into the energy of water evaporation.
