Membrane Technology
Patent awarded for MBR technology developed by CRIQ and INRS
A
US patent has been awarded jointly to Canada’s Centre de Recherche Industrielle du Québec (CRIQ) and Institut National de Recherche Scientifique (INRS) for a system and process that remove emerging micropollutants from industrial wastewater. In preliminary studies the patented membrane bioreactor (MBR) system eliminated 99% of bisphenol A (BPA) and other compounds in heavily contaminated wastewater. BPA, which is used in the manufacture of plastics, is a micropollutant thought to disrupt various physiological mechanisms. The system is designed to be installed at factory outlets to treat wastewater at the source, but it also can be incorporated into wastewater treatment plants. Further work conducted by INRS – a research-oriented branch of the Université du Québec, and CRIQ, a corporation dedicated to making Québec industry more competitive and boosting growth by supporting innovation, productivity and exports – is under way to confirm that this system can also treat water contaminated by six classes of drugs: antidepressants, antibiotics, analgesics, hormones, anticonvulsants and chemotherapy products. Its installation at hospital outlets would prevent these pollutants from dispersing into the environment, where they could have adverse effects and ultimately end up in the food chain. Université de Montréal, the Natural Sciences and Engineering Research Council of Canada, and Centre d’Expertise en Analyse Environnementale du Québec also contributed to the implementation of this project. ‘Since emerging micro-pollutants are not entirely eliminated by processes in existing wastewater treatment plants, CRIQ and its partners in 2008 began developing ways of enabling them to be removed before they reach municipal wastewater collection systems. Results indicate this is an especially promising approach towards protecting the environment from micro-pollutants, which carry real risks for human and animal health,’ noted Gerardo Buelna, research officer at CRIQ. Patrick Drogui, professor at Institut National de Recherche Scientifique, added: ‘The presence of micro-pollutants in effluents carries risks that justify research efforts. The technology developed by CRIQ and INRS, when installed directly at the source in hospitals, could reduce or even eliminate those risks.’

Xylem reveals growth plan to expand MENA operations
G
lobal water technology company Xylem Inc has pledged its commitment to an ambitious expansion plan, and investment of US$35 million in the Middle East and North Africa (MENA) region. It says the expansion will see increased localisation of products and involve building vital local capabilities, including manufacturing, which will provide customers with more highquality, efficient services and products. The company has invested in a number of facilities across the region, including a local manufacturing plant and offices in the United Arab Emirates, Oman and Qatar. Further investment will be made into expanding business services designed to provide customers with smarter technologies and products for their water technology needs. ‘The water–energy nexus is especially relevant throughout the MENA region,’ said Vincent Chirouze, Regional Director, Xylem Middle East and North Africa. ‘We view the low oil price environment as an opportunity to invest and expand in this market whilst many of our competitors are being cautious or even limiting their investments. As the Middle East works hard to address long-term water security in the region, we are positioning ourselves for long-term growth and success.’ In addition, Xylem seeks through its expansion plan to create strategic partnerships with government and private entities to address pressing regional water issues. Xylem and the Masdar Institute of Science and Technology recently announced a research collaboration to establish sustainability indicators such as energy and cost performance of processes and equipment for water and wastewater treatment, and water transport facilities in Abu Dhabi. A critical component of the firm’s bold growth plans in the region is a significant investment in a local manufacturing plant in Dubai. The facility will bring new jobs to the region and provide the market with locally engineered products and services. In 2015, Xylem doubled its local team to support its ambitious growth

NEWS/IN BRIEF plan. Furthermore, the facility will host a training and learning centre, providing training to engineers, contractors and installers in the proper design, installation and maintenance of water-related systems and technology. Xylem moves to the new office in Dubai later this year. It will serve as the headquarters for its regional operations. Contact: Xylem Inc, 1 International Drive, Rye Brook, NY 10573-1058, USA.

Kubota receives order to supply SMUs for MBR project in Oman
K
ubota Membrane Europe Ltd (KME), a subsidiary of Japan’s Kubota Corp, has received an order from Korea’s Doosan Heavy Industries Co Ltd to supply Submerged Membrane Units (SMUs), which will be used to upgrade the Al Ansab sewage treatment plant (STP) in Muscat City, Oman. Because the city is a rapidly developing residential and commercial area, the capacity of the existing STP needs to be expanded. Kubota’s SMUs have been employed at the existing STP for Phase I. They have been stable and produced water that complies with strict regulations ever since they started operating in 2010. The firm says the SMUs are easy to operate and maintain, and together with the unique after service that it provides, are the main reasons why they have been chosen for this expansion project (Phase II). The work needed to increase the facility’s capacity to 120 000 m3/d is scheduled to be completed in August 2017. Many countries in the Middle East have the same problem as Oman. According to Kubota, MBRs are seldom selected for large-scale sewage treatment because there are few references for this technology. It is planning to develop the large-size MBR market in the Middle East using this reference and operational data from the Canton Water Reclamation Facility in Ohio, USA, (160 000 m³/d) which uses its technology (also see Membrane Technology, August, page 16).

Kerui – first Chinese company to export nitrogen generators to the USA
K
erui Group recently shipped its single skid-mounted 1200-Nm3/h nitrogen generator to the USA, following a week-long evaluation by the client. The company says that this is the first membrane-separation nitrogen generation system for use in “oil stimulation” to be exported from China to USA. The system sold to the US client is not based on the traditional double truck-mounted or double skid-mounted design, says Kerui. It integrates the air compressor with the gas booster and uses a high-output engine to drive continuous and efficient nitrogen injection, greatly cutting the operating cost and work space for the client, and making the operation easier and safer. In order to meet the client’s requirements perfectly, Kerui customised the nitrogen generator in various ways. For example, the control interface provides several language options, including Chinese, English and Russian, to guarantee a good user-experience in multilingual scenarios. It also developed a heating upon power-up system for the three core components, namely the air compressor, the engine and the gas booster, and improved the locking system of the shell door. The USA currently holds a dominating position in the field of high-end oil development, oil equipment manufacturing and oil service technologies, making it difficult for products and services offered by developing countries to enter the market place. Kerui says that as a private oil and gas company, which is looking at markets outside China, it has been focusing on innovation and enhancement of its manufacturing capability, and has achieved great success. It has become a major provider of nitrogen-injection technology for oil stimulation, nitrogen generation system manufacturing and nitrogen injection services, which take a 70% share in the Chinese market. It is also carrying out business in Colombia, Peru, Kazakhstan and Kuwait.
