Aware of the importance of coping with effects of climate changes in agriculture production, a specialised Belgian engineering consultancy firm, Asian Infrastructure Engineering and Investment (AIEI) is partnering up with the Vietnamese government to expand green energy investments into the country.
Climate change is happening and it is wreaking havoc by increasing temperatures, leading to salinity intrusion and floods. According to a report of Belgium’s Asian Infrastructure Engineering and Investment Company (AIEI), the total damage from salinity intrusion during the dry season and flood during the rainy season are estimated to reach 30 per cent of the total output of rice, vegetables, fruits, trees, and shrimp in 2050, equivalent to around VND3.6-12 trillion ($156.5-521.7 million).
Especially, over the last years, impoverished areas in coastal and south-central provinces have been facing salinisation, which is impacting production and life. Salinisation has entered about 35-40 kilometres into the Mekong River Delta, with the salinity level at around 14.6-31.2 grammes per litre, and especially, the Tien River has been salinised 90km inwards from the coast.
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.
