Abu Dhabi invited international firms to express interest in building desalination plant – UAE

Bids invited for construction of massive Abu Dhabi desalination plant – Plant will have a capacity of 200 million gallons (757.000 m³/d) per day. Abu Dhabi has invited international firms to express their interest in building one of the world’s biggest water desalination plants as authorities in the UAE’s capital look to increase capacity in order to meet rising demand. Estimated to cost between $600 million and $1.2 billion, the plant will have a capacity of 200 million gallons per day, said Adil al-Saeedi, acting director of privatisation at the Abu Dhabi Water & Electricity Authority (ADWEA), in a [

NGO calls on government to reopen Teshie Desalination plant – Ghana

A Non-Governmental Organization called, Water for Rural Africa has called on the Ghana Water Company Limited (GWCL) and the government to expedite the re-opening of the Teshie Desalination plant. GWCL ordered the shutdown of the plant effective January 1, 2018, for a renegotiation of the contractual agreement between the company and the managers of the plant, Messrs Befessa. Residents of Teshie, Nungua and other surrounding communities, have experienced poor quality and inconsistency in water supply to the area following the shutdown of the desalination plant. According to them, they receive water only twice each week, which takes place at [

Evoqua’s modules in wastewater recovery and reuse

EDR skid featuring two NEXED6-8A-0 modules. A new installation of Evoqua’s NEXED Electrodialysis Reversal (EDR) module, part of the Ionpure product family, is up and running. The EDR system recovers Reverse Osmosis wastewater which was previously sent to drain. 85% of wastewater recovered. – The system was engineered and built by Agape Water Solutions, Inc. and installed by Northeast Water Services Inc. Nexed technology treats Reverse Osmosis concentrate with varying salinity and recovers 85% of the wastewater. The recovered 85% is of equal or better quality than the RO feed water and is returned to the RO inlet. Northeast [

Teshie, Nungua residents struggle for water – Ghana

Residents of Teshie, Nungua and other surrounding communities have expressed their dissatisfaction at the quality and consistency of water supply to the area following the shutdown of the desalination plant by the Ghana Water Company. According to them, they received water two or three days in a week and it comes at dawn making life unbearable for them. Others also complain bitterly about the quality of the water, lamenting that it has a brownish colour with an unpleasant smell and poses serious health risks to them. The Ghana Water Company directed the shutdown of the plant effective January 1, [

Membrane-Based Salinity Gradient Processes for Desalination Handbook

Two Swansea University chemical engineering academics have written a handbook which reviews current state-of-the-art developments in salinity gradient processes in desalination, one of the most promising technologies to improve energy efficiency in desalination. The impending crisis posed by water stress and poor sanitation represents one of the greatest human challenges for the 21st century, and membrane technology has emerged as a serious contender to confront the crisis on a global scale. Seawater desalination is poised to become one of the main alternative freshwater resources as almost 60% of the world’s population live less than 36 miles from a seacoast. Membrane-based processes [

6 power and water companies to launch IPOs in next 3 years – Muscat- Oman

 As many as six power generation and water desalination companies will launch their initial public offerings (IPOs) to list on the Muscat Securities Market (MSM) within three years, according to Oman Power and Water Procurement Company (OPWP). As per their project founders agreements, Oman’s independent water and independent power projects are required to offer a minimum 35 per cent of the share capital to the public within four years of the incorporation of the company. ‘There are six power and water sector projects that will be going for IPOs within next three years. Out of these six projects, four [

Battery electrode deionization (BDI) -improvement of capacitive deionization (CDI)

A feed solution contained in a reservoir was separately fed to the two inlets of the flow cell using pumps, one desalinated and the other concentrated. This is achieved by applying electrical current to the flow cell through wires using a power source (not shown in this photo). The conductivity of the discharge was then measured using flow conductivity meters located at each outlet, which were monitored by computer. Credit: Taeyoung Kim

Rich Mesostructures Derived from Natural Woods for Solar Steam Generation




A tree is a living energy-water system. Intensive study of tree-derived natural wood is of great significance for the sustainable development of human civilization and reduced dependence on nonrenewable resources. Here, we report on the mesostructures of several natural wood materials as well as their thermal conductivities and mechanical properties. We found that natural wood, including hardwood and softwood, possesses excellent hydrophilicity, an interconnected pore network, low thermal conductivity, and various mechanical properties. Inspired by the critical ecological energy-water nexus, high-efficiency solar steam generation based on natural wood is demonstrated in this work. The variation in multiple [

Egyptian government seeks to use its surplus electricity production in the construction and operation of new desalination plants

The Egyptian government seeks to use its surplus electricity production in the construction and operation of new desalination plants to bridge the potential water gap in Egypt. Government sources said that Egypt surplus electricity production currently stands at 6,000 MW per day, and will increase to 10,000 MW in the summer, benefiting from the added capacities from Siemens new power plants in the New Administrative Capital, Brulus, and Beni Suef. The sources added that the government is currently in talks with five international companies, including Schneider Electric and Siemens AG, to establish desalination plants in cooperation with the [
