Thermal spa relies on UF technology
NEWS with a production capacity of 38 500 m3 (10.2 million gallons) per day, and a RO desalination unit with a production capacity of 128 000 m3 (33.8 million gallons) per day. The plant is scheduled to be commissioned during 2010. ‘We are pleased to be involved in this project which, coming just a few weeks after the Marafiq contract in Saudi Arabia, strengthens our already solid presence in this region. The consortium’s decision to opt for hybrid desalination shows that Veolia Water has the capability to invent and implement the most innovative systems and technologies available in this field,’ said Antoine Frérot, Chief Executive Officer of Veolia Water. The project is headed by a consortium set up by the public authority Abu Dhabi Water and Electricity Authority in collaboration with International Power Plc and Marubeni Corp. Veolia Water’s share of the contract represents US$805 million (596 million) of revenues over the duration of the project. Operating in Saudi Arabia since the 1970s, SIDEM now boasts 73 desalination facilities in the region. VWS is the technology subsidiary of Veolia Water, a division of water and wastewater services company Veolia Environnement. Contact: Veolia Water, 52 rue d’Anjou, 75384 Paris Cedex 8, France.

Inge says that the membrane fibre it has developed combines several single capillaries – a structure that differs considerably from conventional single-bore capillary products – resulting in a high degree of stability and resistance. To optimise hydrodynamic activity, and to ensure longevity and a clean and secure treatment process the capillaries are firmly locked into position inside the Dizzer Multibore module. W.E.T. says that since 2003 it has installed a total of 32 recirculation systems for treating bathing water, with a total capacity of 2135 m3 (564 000 gallons) per hour. Another 13 recirculation systems, with a total capacity of 1420 m3 (375 100 gallons) per hour (including the Bad Aibling project), are currently being constructed. Inge AG is based in Greifenberg near Munich, Germany. The company manufactures and sells UF membranes and modules for the treatment of drinking water, process water and wastewater. It is one of the largest UF corporations in Germany that is involved in water treatment technology, and currently employs over 50 people. In order to meet increasing demand from markets in Asia, the company also maintains a sales office in China. Contacts: Inge AG, Flurstrasse 27, D-86926 Greifenberg, Germany.

Thermal spa relies on UF technology
W
hat is believed to be the world’s largest ultrafiltration (UF) plant designed to process water for a bathing spa is opening in the German city of Bad Aibling. The system, which uses 92 Dizzer UF membrane modules from Inge AG, has a total treatment capacity of 800 m3 (211 300 gallons) of water per hour. W.E.T. GmbH of Kasendorf, Germany, the firm that has manufactured the UF system which is being used at the spa, says the positive experience it has gained in applying modules manufactured by Inge was a crucial factor in selecting the company for the Bad Aibling project. The water at the spa goes through a series of stages while it is being treated. After being transferred from the splash container, a flocculating agent is added to the water. A reduction in the bound chlorine is achieved by adding powdered activated carbon. Following UF by the Dizzer modules, the necessary pH adjustments are made. After the required chlorination the water flows back into the spa’s ‘basins’. As part of the treatment process disc or gravel filters are used to protect the UF membranes. 4
Membrane Technology
Hydranautics launches low-fouling element
U
S-based membrane technology company Hydranautics/Nitto Denko has launched a low differential pressure element which, it claims, is ideal for use in applications that involve high fouling feed-water. According to the firm, which is based in Oceanside, California, industries requiring high purity water – particularly those in developing countries with limited access to municipally treated feed-water – will reap the benefits of this hard-to-foul, yet high performance element. The composite polyamide CPA3-LD (low differential pressure) spiral-wound reverse osmosis (RO) element uses a 0.8-mm (31-mil) brine spacer, which is thicker than the one that is normally used. This lowers the differential pressure, making it a perfect fit for scenarios that demand a low fouling and low maintenance membrane while maintaining a high permeate flow, says the company. The 31-mil spacer also enhances the flux distribution in the RO system. Efficiency is improved because
there is less flux loss in the pressure vessel from membrane to membrane. In the past, membrane area typically had to be sacrificed when using a thicker brine spacer. Hydranautics says that using automated manufacturing technology it can maintain the element’s 37-m2 (400-ft2) area, and performance, and still use the thicker 31-mil spacer. CPA3-LD membrane elements are available in a 20-cm (8-inch) diameter and 102-cm (40-inch) long configuration, and can be used as either a stand-alone product or part of the firm’s Integrated Membrane Solution (IMS). Hydranautics’ CPA3-LD provides around 41 m3 (11 000 gallons) of water per day at 99.7% nominal salt rejection. Hydranautics was founded in 1963, and during 1987 it became part of the multi-billion dollar Nitto Denko Corporation, based in Osaka, Japan. The company manufactures RO, nanofiltration and ultrafiltration membrane products for water treatment applications around the world. Contact: Hydranautics, 401 Jones Road, Oceanside, CA 92054, USA.

CBM plants use ionexchange technology

G Global Lifestyles Incorporated of Rancho Santa Margarita, California, USA, has awarded turnkey plant construction and installation contracts for two water treatment plants to Rimon Limited, a water management and treatment business based in Israel. Incorporating RG Global’s proprietary Catalyx ion exchange technology, Rimon will provide the equipment and installation services for the water treatment plants, which will be used by Black Diamond Energy and Yates Petroleum to remove contaminants from water associated with coal bed methane (CBM) production. During 2007, RG Global’s Catalyx Fluid Solutions (CFS) division signed a contract with Black Diamond Energy to build a CBM wastewater treatment plant rated at 20 000 barrels per day, and has subsequently signed a five-year US$20-million contract with Yates Petroleum to operate a CBM water treatment plant for the company. ‘RG Global is a technology provider that focuses on developing unique technologies which reduce operating costs of current water treatment processes in many areas,’ said Juzer Jangbarwala, Chairman and Chief Technology Officer of RG Global. ‘By vertically integrating the manufacturing of major components used in water treatment plants,
