Patent number: 6841069Abstract: The present invention relates to the raw water-filtering technical field, and is to provide a high speed filtering apparatus which can filter a great amount of raw water containing suspended substances (SS) at a high concentration at a high speed. Floating filter media 2, which are composed of a foamed polymer having an apparent density of 0.1 to 0.4 g/cm3 and a 50% compression hardness of not less than 0.1 MPa and have uneven shapes or cylindrical shapes with sizes of 4 to 10 mm, are charged into an up-flow type filtering tower 1. The raw water containing SS at a high concentration is filtered by passing it through the filtering tower 1 at a linear water-passing speed of 100 to 1000 m/day. While the floating filter media 2 are not compacted, a high SS-capturing percentage can be obtained. Back washing can be also effected at a high linear washing speed of 1.2 to 4.0 m/min.Type: GrantFiled: March 11, 2002Date of Patent: January 11, 2005Assignee: NGK Insulators, Ltd.Inventors: Yoshihiko Nakayama, Atsushi Miyata
