Hitachi Develops Marine Purification System for Pollution Caused by Ballast Water.Tokyo, Japan, Sept 27, 2006 - (JCN JCN Japan Corporate News JCN Journal of Cognitive Neuroscience JCN Journal of Cardiovascular Nursing JCN Journal of Christian Nursing JCN Job Control Number JCN Journal of Child Neurology JCN joint communications network (US DoD) ) - Together with Hitachi Plant Technologies, Hitachi has developed a system to purify ballast water that is used to keep the horizontal balance of a ship but considered to cause marine pollution as it contains planktons and bacteria in a variety of sea areas. The system is built on the combination of the agglomeration ag·glom·er·a·tion n. 1. The act or process of gathering into a mass. 2. A confused or jumbled mass: techniques used in water treatment plants with the company's commercial superconducting electromagnetic separation technology to purify blue-green algae blue-green algae, popular name for those microorganisms that are now more properly called cyanobacteria. and other phytoplankton phytoplankton Flora of freely floating, often minute organisms that drift with water currents. Like land vegetation, phytoplankton uses carbon dioxide, releases oxygen, and converts minerals to a form animals can use. . As the system does not use chlorines and ultraviolet rays Ultraviolet rays Invisible light rays with a wavelength shorter than that of visible light but longer than that of x rays. Mentioned in: Sunscreens , the purified water does not cause cross-contamination; and the efficiency of the system is achieved by the agglomeration technique, which speeds up the flow of water. The system will be tested between September 25 and the end of December in the Tokyo Bay, and presented at the 3rd International Conference & Exhibition on Ballast Water Management at Singapore on September 25.
