Toray to double production of water treatment membranes in China – China

Japanese materials manufacturer Toray Industries will build a new plant to make water treatment membranes in China, doubling its production capacity in a country facing water shortages.

The new plant is estimated to be a 10 billion yen ($89.7 million) investment, and will be built in Foshan, Guangdong Province.

It is to begin producing reverse osmosis membranes in 2021.

The high-performance membranes are in demand in China, where they are used to purify drinking water and to filter impurities from water for industrial use.

Northern China in particular has suffered chronic shortages, and securing clean water is considered crucial not just for daily living but to support economic growth.

Sweet water for Vietnam – Vietnam

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.

AIEI is a sister company of the investment company Rent-A-Port, which is well-known for the development projects of DEEP C (Dinh Vu) Industrial Zones in Vietnam.

For the desalination mission, AIEI is collaborating with SCE, a company of Keran Group from France, enabling public and private parties to benefit from a global approach in development projects.

Wind powered water desalination in coastal Vietnam – Vietnam

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.

Kinmen County completes desalination plant expansion – Kinmen – China

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.

Speaking at the celebration ceremony, Kinmen County government secretary-general Lin Te-kung (林德恭) said the expanded plant will contribute significantly to supplying the county’s water needs.

According to the Water Resources Agency (WRA), the facility is expected to supply 4,000 cubic meters of freshwater per day, up from its daily production of 500 cubic meters before the project began.

Govt opts for Chinese funded desalination plant – Windoek – Namibia

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.

Ion concentration polarization (ICP) – Low-Cost and Pump-Free Water Desalination

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.
