Cutting the ribbon at the opening of Evonik’s new membrane plant in Schörfling, Austria. Evonik Industries has opened another membrane production facility at its plant in Schörfling, Austria. The new hollow fibre spinning plant will mainly produce membrane modules for nitrogen generation and for process gases. Evonik currently produces gas separation modules in Schörfling largely for the biogas market and for helium recovery. This latest investment doubles the production capacity for Sepuran® membranes. Along with the new hollow fibre spinning plant, there are now additional facilities for technology development, application technology, membrane testing and quality assurance, with more than 30 new jobs created in production and administration. The company’s plant in Lenzing, near the Schörfling site, manufactures the source material polyimide, which is spun and then further processed in Schörfling. The infrastructure in Lenzing is also being upgraded as part of the Schörfling site expansion. “The Schörfling investment expands our possibilities for placing the membrane portfolio on an even broader footing. Our aim is to offer our customers and partners custom-tailored membranes in the entire gas separation market,” said Dr Claus Rettig, chairman of Evonik Resource Efficiency GmbH’s board of management. Dr Harald Schwager, deputy chairman of Evonik’s executive board, said: “The membrane business is an excellent example of how important innovations are for corporate success. Here, we are generating growth for Evonik with new products, and harnessing new markets in close cooperation with our customers.”


Besix opens Desalination plant in Ajman – UAE

Belgian construction group Besix has announced the opening of a water recycling station in Ajman, UAE, following a major renovation work which will now boost its per day production capacity to 2.2 million gallons from the previous 300,000 gallons. The Safi Water Recycling Station, located at the Al Jurf Industrial Area, has been renovated at a cost of Dh30 million ($8.16 million), reported state news agency Wam. The facility will first obtain water from the Ajman Sewage Treatment Plant which will then be processed through micro-filtration and reverse osmosis process to make it pure. It will be later distributed across the emirate for industrial and commercial purposes round-the-clock, it stated. The Safi Water Recycling Station was opened by HH Sheikh Humaid bin Rashid Al Nuaimi, Supreme Council Member and Ruler of Ajman in the presence of senior government officials. Following the opening, Sheikh Humaid was shown around the station and briefed about the state-of-the-art-technology used in the desalination process, said the report. Lauding the project, Sheikh Humaid said Safi Water Recycling Station marks a qualitative leap in areas of water recycling for industrial and commercial businesses in the emirate, it added. (LINK)

Desalination IPO opens for subscription – Muscat City – Oman

MUSCAT, NOV 18 – Muscat City Desalination Company (MCDC) SAOG (under transformation) has announced the opening of its Initial Public Offering (IPO) for subscription from today, November 19, 2017. Bank Muscat is the financial adviser and issue manager for the IPO. The founding shareholders, who are leading international names in the industry, are selling these shares to the public to comply with their obligations in the Project Founder Agreement signed with the government of Oman. MCDC is offering 54,442,640 offer shares at a price of 116 baisas per offer share (comprising a nominal value of 100 baisas, premium of 14 baisas and offer expenses of 2 baisas per offer share). The IPO represents an offer of 35 per cent of the share capital of the company. The IPO opens for subscription today (November 19) and will close on December 18, 2017. The IPO is open for subscription to Omani and non-Omani investors including individual and institutional investors. In the IPO, 65 per cent of the shares made available for subscription have been reserved for investors applying for a minimum of 1,000 shares and a maximum of 500,000 shares, and 35 per cent of the shares have been reserved for investors applying for a minimum of 500,001 shares up to a maximum of 5,444,200 shares.
According to Subrina Thiagarajah, CEO of MCDC, the company (MCDC) has “steady and reliable cash flows with a stable business model based on a 20-year offtake agreement with Oman Power and Water Procurement Company (OPWP), which is owned by the government of Oman. The agreement is 33 per cent longer than the 15-year term given to power companies.
This would translate into cash flow visibility for a longer period for MCDC shareholders.” She added that the plant operations and maintenance is contracted for 20 years to experts with international experience. The company also benefits from marquee Project Founders — Malakoff International (Malaysia), Sumitomo Corporation (Japan) and Cadagua S A (Spain) — that are strong and experienced, having extensive expertise and demonstrated track record in the global water industry. Together, the Project Founders have experience in combine water production capacity exceeding 7.5 million cubic metre per day. The company’s management team is also highly experienced. Tamer Cankardes, Vice Chairman of Board of Directors of MCDC said the company is the owner of Oman’s largest operating desalination plant, the Ghubrah Independent Water Plant (Ghubrah IWP) located in Muscat, with a total investment of more than RO 100 million. The plant was commissioned in February 2016, with a 21-month successful operating records, hence the company has full operating assets, with no construction and commissioning risk. “MCDC contracted a water capacity of 191 TMC/day, making it the largest operating water plant in Oman. The plant, with a total capacity output to deliver 42 million gallons of potable water every day, provides approximately 24 per cent of total water capacity based in the Interconnected Zone and 60 per cent of the total water demand for Muscat city.” He also added that the plant, based on globally proven and reliable seawater reverse osmosis technology, helps the company deliver uninterrupted water supply with minimum outages. Seawater reverse osmosis technology-based desalination plant process is relatively simpler as compared to that of a power plant. “Key inputs are just seawater and electricity, hence there is no direct dependence and risk of gas allocation unlike in power plants.” Cancardes reiterated that the plant is set to perform well once the Water Purchase Agreement with Oman Power and Water Procurement Company (OPWP) expires as it is expected to be competitive and well placed in the water demand and supply landscape. The company has no outstanding liquidated damages with OPWP. (LINK)

Solar-powered device generates electricity through ion transport and could lead to low-cost for seawater desalination

By binding photosensitive dyes to common plastic membranes and adding water, chemists at the University of California, Irvine have made a new type of solar power generator. The device is similar to familiar silicon photovoltaic cells but differs in a fundamental way: Instead of being produced via electrons, its electricity comes from the motion of ions. Dubbed the “synthetic, light-driven proton pump” by its creators, the innovation – because of its ionic basis – has the added potential capability of taking the salt out of seawater. “The materials used to make such a device can be dirt-cheap,” said Shane Ardo, UCI assistant professor of chemistry, as well as chemical engineering & materials science, and senior author of a paper describing the generator published today in the Cell Press journal Joule. “We’re talking about common polyethylene plastic, light-absorbing dye molecules and water.” In Ardo’s laboratory, researchers devised a system based on dual layers of dye-coated, ion-transporting membranes. When struck with light from a laser pointer – a laboratory simulation of sunlight – the dye releases ions. Positively charged protons, also known as cations, pass through one sheet, while negatively charged hydroxides, also known as anions, pass through the other. These photoactive membranes generate 60 millivolts, on average, occasionally climbing to more than 100 millivolts, as measured by Ardo’s team. “Our results represent considerable progress toward a device that directly converts sunlight into ionic electricity, which has implications for direct desalination of seawater,” Ardo said. When speaking in public about this research, he often holds up an ordinary plastic water bottle and asks, “What if it were possible to dip this container in the ocean, let it sit in full sun for about an hour and then be able to drink the water? The prospect of that is revolutionary.” According to lead author William White, a graduate student in Ardo’s lab, scientists have been trying to develop an ion-exchange power generator for decades with limited success. “There had been other experiments dating back to the 1980s that photo-excited materials so as to pass an ionic current through them,” he said. “Theoretical studies said that those currents should be able to reach the same levels as their electronic analogs, but none of them worked all that well.” The researchers see other possible applications for the technology, including as part of a brain-computer interface system. Silicon-based devices and aqueous environments don’t mix, but the flexible, fluid-permeable structures being developed in the Ardo lab may one day offer a way of integrating living tissue and artificial circuitry. This work was supported by UCI’s School of Physical Sciences and the Gordon and Betty Moore Foundation.


Cabo Verde (formerly Cape Verde) 100% renewable including desalination

One novel part in the puzzle may be the nation’s desalination systems, which provide drinking water for much of the population. They currently use large amounts of electricity, but by scheduling their use to times when wind turbines are operating and when electricity demand is low will help maximise their efficiency. And pumping this water up into reservoirs during these minimal usage periods will also enable hydroelectric power to be harnessed at times when more electricity is in demand.


Desalination: Cape Town’s solution to water shortages – South Africa

Minister of local government‚ environmental affairs and development planning in the Western Cape, Anton Bredell, says the province has been managing drought conditions in some parts of the region since 2010. “Three years of below-average rainfall have exacerbated the situation and despite proactive measures like the implementation of water restrictions and programmes to clear the Berg River of alien vegetation‚ the reality is we are faced with a dire situation.” Inspired by the Target 140 Campaign implemented in South East Queensland, Australia, Cape Town embarked on reducing water usage. So far residents’ water usage has dropped below 100 litres per person per day, making the City’s Water Conservation and Water Demand Management Programme one of the most successful water conservation projects globally – a fact recognised at the 2015 C40 Cities Awards in Paris. Mayor Patricia de Lille thanked Capetonians and commended them “for rising to the occasion to save more water in our City because we are determined that we will not allow a well-run City to run out of water”. The mayor told the media the City will run out of water by March next year, at current usage levels. Despite water restrictions and the water savings achieved, Cape Town still needs 450 megalitres of water a day. With no end to the drought in sight, the City has approved plans to build a desalination plant to turn salty sea water into potable water. Construction will begin in December at the V&A Waterfront, the first approved site. By February the plant will feed two million litres of water into municipal networks. The harbour site will allow the City to draw water from the harbour and pump the salt brine residue into the ocean. As David Green, V&A Waterfront chief executive officer, explained: “At peak we have about 7m tidal waves, which means that there is no issue in terms of marine life, the brine is cleared immediately.” The V&A plant is the first of a possible eight the City wants to build. Down from an original 17, the other sites include Dido Valley‚ Granger Bay, Harmony Park, Hout Bay‚ Monwabisi, Strand and Strandfontein. The plants will have a working life of two years and, it is hoped, will supply the City with up to 15 million litres of usable water a day…. (LINK)

Rolls-Royce sign MoU to build Small Modular Reactor (SMR) to Jordan

The Jordan Atomic Energy Commission (JAEC) has signed a MoU with Rolls-Royce to conduct a technical feasibility study to build a Small Modular Reactor (SMR) program for power generation and water desalination in the Kingdom, the JAEC said Friday. The MoU provides for cooperation between the two sides to identify technical, economic, financial and safety factors for building the 440-Megawatt SMR program, the Jordan News Agency (Petra) quoted JAEC Deputy Chairman Kamal Al-A’raj as saying. Al-A’raj signed the memo with Director Strategy and Business Development at Rolls-Royce Alan Woods in the British embassy in Paris. JAEC Chairman Khale Toukan told Petra today that the memo is of great importance and it comes within Jordan’s endeavors to add nuclear power to the Kingdom’s energy mix. He said Rolls-Royce champions a British consortium to design the SMRs, which are low cost and reduce carbon emission. In October 2013, the Jordanian government said that it had contracted Russia’s Rosatom to build the Kingdom’s first two nuclear reactors, 1000-Watt each. They are expected to be operational by 2022.
