The Industrial Development & Renovation Organization of Iran (IDRO Group) and China’s ZSM signed an agreement whereby the Chinese firm will set up a water treatment facility in Iran’s western province of Ilam.
Taiwan’s outlying Kinmen County celebrated on Monday the completion of an expansion of a local desalination plant that should help increase freshwater supplies and ease the threat of water shortages in the island county.
In a shock move which is likely to worsen the central region’s water woes, government has opted to construction its own desalination plant using proceeds from the N$10 billion that it has requested from China.
The long-term move, which is unlikely to bring the much-needed relief to the existing water woes faced by the central region which has started using boreholes as supply dams run dry, is expected to drag further the issue of securing consistent water supplies.
Koch Membrane Systems, Inc. (Koch), a global leader in membrane filtration technologies, announced today its PURON® Membrane Bio-Reactor (MBR) modules have been selected for the Ji’nan Wastewater Treatment Plant I and Plant II Expansion Project.
This project continues the strong presence of Koch’s PURON® MBR in various municipal and industrial wastewater treatment projects in China, demonstrating exceptional performance and creating value to clients.
DUBAI — ACWA Power, a leading developer, owner, and operator of power generation and water desalination plants, on Saturday signed a Memorandum of Understanding (MoU) with China Energy Engineering Corporation Limited, a global leader in international engineering and EPC contracting, during a ceremony in Dubai.
Federal Minister for Ports and Shipping Mir Hasil Khan Bizenjo inaugurated a desalination plant on Monday installed at the Gwadar port by China Overseas Port Holding Company for supplying drinking water to the people in the port city.
Low-cost small-scale water desalination could be very useful to ensure the supply of drinking water in developing and remote areas. Ion concentration polarization (ICP) is a desalination technique that requires little energy, which could make it suitable for such applications. The method works by applying a voltage to an ion-selective membrane, which causes a depletion of ions around the membrane. This zone repels charged species. However, the technique is usually performed using expensive microfluidic devices. Hong Liu and colleagues, Southeast University, Nanjing, China, have developed a low-cost, fabric-based desalination setup that uses ICP. The team used polyester fabric, cut to form a Y shape. Near the bifurcation, a Nafion membrane was placed on the fabric and the device was laminated in plastic to ensure good contact between membrane and fabric. One end of the fabric was placed in a water reservoir, and a voltage was applied to the Nafion membrane to induce the ICP effect. Brine and desalinated water could then be separately collected from the two other ends of the Y-shaped fabric. Due to capillary flow in the fabric, no pump is needed. The device’s salt rejection rate depends on the applied voltage. Above 15 V, it produces drinkable water. The team calculated the cost of desalination and, depending on the salt concentration and applied voltage, the cost for 1000 L is between 12 and 43 USD. The fabric also filters the water due to its porous structure, which causes a purification effect during the process.
China plans to increase its sea water desalination capacity more than fivefold during the next three to five years to ease a water shortage on its inhabited islands. Around 100 sea water desalination projects will be built or upgraded in 16 coastal provinces and cities, adding 600,000 tonnes of daily desalination capacity to the existing capacity of 135,700 tonnes, according to a plan issued by the National Development and Reform Commission and the State Oceanic Administration. By 2020, desalinated sea water is expected to become the main source of water for islands suffering a severe water shortage, according to the plan. China has more than 11,000 islands in the sea, of which 489 are inhabited with an area of at least 500 square meters. More than half of the inhabited islands depend on pipe systems or cargo boats for water supply. The news lifted stock prices of relevant companies Wednesday. Beijing Originwater Technology climbed 1.26 percent in the morning to 16.86 yuan (about 2.6 U.S. dollars). Zhejiang Hailiang Co. shares ended the morning session up 0.38 percent to 7.86 yuan.
China’s sea water desalination capacity has grown for three straight years, with 158 sets of equipment installed as of the end of 2016.
The daily desalination capacity exceeded 1.38 million cubic meters, according to figures made public at a forum on water pollution control and ecological protection that ended Monday in Hangzhou, capital of east China’s Zhejiang Province. Nearly 70 percent of China’s desalinated sea water was for industrial use as of the end of last year. In northern China’s Liaoning, Hebei and Tianjin regions, desalinated water mainly supplies the hydropower, steel and chemical industries. In southern China’s Zhejiang and Guangdong regions, the water is used for human use in coastal areas and islands. China is one of only a few countries with the overall capacity to desalinate sea water, said Yang Shangbao with the National Development and Reform Commission. A work plan for the country’s scientific and technological development from 2006 to 2020 considers research on low-cost technology and materials for sea water desalination a key task. Zheng Genjiang, a senior engineer with Hangzhou Water Treatment Technology Development Center, suggested the government subsidize and better regulate the industry. The country’s Belt and Road Initiative will help domestic producers tap into the international market, Zheng said. .. (LINK)
The daily output of China’s 131 seawater desalination projects reached more than 1.18 million tonnes by the end of 2016, according to an official report released Wednesday. Sixty-six percent has been used for industrial purposes and the rest for residential use. China will speed up the legislation on seawater utilization, expand the use of seawater and address public concerns over drinking desalinated seawater, said Qu Tanzhou, head of science and technology department under the SOA.
