The ¥ 25 billion (US$ 242.8 million) order will also include operation and maintenance management for a period of five years. Hitachi will oversee the project as the leader of consortium. Construction of the 199,000 m 3 /d reverse-osmosis plant is scheduled to begin in February 2014, with completion scheduled for July 2016. Existing water purification facilities in Basrah, with a total capacity of 400,000 m 3 /d, are unable to keep up with the city's huge demand for fresh water, which is estimated at up to 900,000 m 3 /d, and are deteriorating. The new plant will purify river water drawn from close to the river mouth, where salinity is relatively high. This will be Iraq's highest capacity single water-purification plant, capable of supplying 400,000 people. This is the first time since the end of the Iraq war that a Japanese company has received an order for a large-scale water infrastructure project based on internal funds from the Iraqi government, rather than Japanese government yen loans. fouling-resistant rO membranes get powerplant use Lewabrane fouling-resistant reverse osmosis (RO) membranes are being used on a large scale for the first time at the Dammweg thermal power station in Chemnitz, Germany, membrane manufacturer Lanxess announced on 8 January 2014. Sixty Lewabrane RO B400 FR filter elements are cleaning 50-60 m 3 /h of pretreated river water for steam-generation purposes. Even after it has been softened and desalinated using ion-exchange resins, the water still contains a considerable amount of organic material that causes excessive conductivity in the water-steam cycle, which is harmful to the turbine and other components. The Lanxess membrane elements lower the degree of fluctuation in water quality and filter out organic substances. Some 90% of the feed water, the permeate, is used for the ensuing processes. The remaining concentrate is also put to further use by adding it to the process water. Dr Jens Lipnizki, head of technical marketing membranes in the Liquid Purification Technologies business unit at Lanxess, explains that "the 90% reduction in the organic contamination of river water demanded by the operator of the power plant can be easily achieved using our membrane technology." The RO facility at Chemnitz was developed and designed by the Celle-based water technology company Berkefeld, a subsidiary of Veolia Water Solutions & Technologies. Sembcorp to build Chinese wastewater plant Sembcorp announced on 19 December 2013 that it would be developing a new industrial wastewater treatment plant in the Caofeidian Chemical Industrial Park in Hebei province, China. The Singapore-based company has entered into an agreement through its wholly-owned subsidiary, Sembcorp (China) Holding Co, to set up an 80-20 joint venture with Tangshan Caofeidian Yongtai Industry Co, a wholly-owned entity of the Caofeidian Industrial Zone Administrative Committee. The joint venture company, Sembcorp Caofeidian Water Co, will build, own and operate an industrial wastewater treatment plant to serve customers in the chemical industrial park. Targeted to begin operations in late 2015, this wastewater treatment facility will have an initial capacity of 10,000 m 3 /d and have advanced capabilities to treat high concentration industrial wastewater and high oil content industrial wastewater. The joint venture has secured a 30-year exclusive concession agreement to provide wastewater treatment services within a 32-km 2 area in the chemical industrial park. In addition, it has already secured binding letters of intent from two key customers. The joint venture's total investment in the project of around RMB 108.3 million (approximately US$ 17.8 million) will be funded through a mixture of internal sources and external borrowings. Sembcorp's equity investment in the project of approximately RMB 35 million (US$ 5.8 million) will be funded through internal sources.
