Abstract:
PURPOSE: A filter structure for treating water with multiple filtration is provided to improve durability by being formed based on a material with anticorrosive property to seawater. CONSTITUTION: A plurality of filter structures(100) for treating water with multiple filtration includes a first filter(110) and a second filter(120). The first filter is composed of a mesh member(111). The second filter surrounds the first filter. The second filter is composed of another mesh member(121). The filter structure implements a multi-filtering operation in a limited volume. The filter structures are arranged in a housing forming a water treating apparatus. The first filter is conically shaped, and the second filter is cylindrically shaped. The narrow peak part of the first filter is toward the upper side of the second filter.
Abstract:
PURPOSE: A sludge dehydrator is provided to improve the dehydration rate of sludge by condensing and dehydrating the sludge using a moving body, and applying an electric infiltrating dehydration mode at the same time. CONSTITUTION: A sludge dehydrator(1) includes a case(10), a moving body(20), a filter(30) and a power applying unit(40). The case includes a sludge inlet and a sludge outlet. The moving body is installed in the inside of the case, for transferring the sludge from the inlet to the outlet while condensing and dehydrating. The filter is installed inside the case to surround the moving body, for filtering the moisture dehydrated from the sludge. The power applying unit applies opposite polarities to the moving body and the filter.

Abstract:
A device for collecting autogenous bone. When collected bone is mixed with other material, the filter is held by a waterproof filter holder such that the bone needs not be moved to another container. The, filter holder is properly fixed to an operation cuff or an operating table via adhesive tape or magic tape. Thus, the filter for filtering the bone can be prevented from falling such that the bone can be easily collected. In addition, the filter holder is transparent or translucent, and includes a scale thereon such that a volume received in the filter holder can be easily measured. Thus, bone collected in the filter is prevented from loss or contamination from saliva, blood, or other unwanted constituent.
