Abstract:
PROBLEM TO BE SOLVED: To provide a filter that is excellent in mass productivity and durability with its simple structure, is comprised of a core hardly deformable during its transportation or its assembly, can easily be assembled and handled, is excellent in its efficiency and reliability in scaling off deposits by backwashing or the like, and is excellent in maintainability and in long life characteristics with its filtration capacity maintainable for a long period of time. SOLUTION: The filter includes a core and a bag-shaped filter cloth covering the whole body of the core and discharges the filtrate of a waste water suspension filtrated from the outer surface side of the filter cloth via a shaft pipe penetrating the core and the filter cloth, and is characterized by comprising an inner flow path formed inside the core, a plurality of communication holes each communicating with the inner flow path and opening to the front and back surfaces of the core, and a through-hole penetrating the core and the filter cloth with the shaft pipe inserted thereinto and firmly held thereby.

Abstract:
PROBLEM TO BE SOLVED: To provide a turbid material removing device which can always locate an intake port in a surface layer where a turbid material is stagnant at high concentrations. SOLUTION: The turbid material removing device has a first floating body floating in a predetermined water area, and a second floating body movably floating in the predetermined water area independently from the first floating body. The first floating body 2 is provided with a pump, and the second floating body 3 is provided with an intake member 34 having an intake port 35 formed at a location that opens toward the surface layer in the predetermined water area. An interval between the intake member 34 and the pump 17 is connected by a suction hose S1 with flexibility so as to allow the movement of the second floating body 3 with respect to the first floating body 2, and the pump 17 has a discharge hose S2 connected thereto which communicates with the outside of the predetermined water area. Then the turbid material flowing from the intake port 35 into the intake member 34 together with water is introduced via the suction hose S1 to the pump 17 together with the water, and discharged via the discharge hose S2 to the outside of the predetermined water area by the pump 17.

Abstract:
PROBLEM TO BE SOLVED: To gather and sample a suspended matter in a water area of a wide range with little work and cost, by easily arranging a device required for sampling the suspended matter drifting over the wide range in the water area. SOLUTION: A plurality of rope guide members 2a to 2d are arranged at an interval in the peripheral direction on the periphery of the set water area S. A rope 3 is successively extended to and endlessly tensioned on these rope guide members, and a floating body 5 for holding a suction port is arranged in a central part of the water area S. Silt fences 6a and 6b are tensioned between the floating body and the endless rope. The endless rope is circularly driven, and the silt fences are revolved along a water area surface around the floating body, and a vortex flow with the suction port as the center is generated in the water area by revolution of the silt fences. The suspended matter is carried on this vortex flow, and is guided to the suction port. COPYRIGHT: (C)2007,JPO&INPIT
