A magnetic field generator comprises a superconducting bulk body, which generates a superconducting magnetic field, a refrigerant vessel for storing solid nitrogen, a vacuum container, which accommodates therein the superconducting bulk body and the refrigerant vessel, and a refrigerator having a cooling head for cooling the refrigerant vessel. The superconducting bulk body is arranged along a wall of the vacuum container. The cooling head of the refrigerator and the refrigerant vessel are in thermal contact with each other. The refrigerant vessel and the superconducting bulk body are in thermal contact with each other.

A cryogenic storage container is provided with a storage container, a vacuum container containing the storage container, and a heat shield. The cryogenic storage container is coupled to a cooling source equipped with a cryogenic freezer via transport piping so that the vibration of the cryogenic freezer cannot be directly delivered to the cryogenic storage container. The vibration can be further reduced by providing a bellows unit for transport piping.

In supplying domestic treated water into which domestic wastewater is treated to demanders of the domestic treated water by transporting the domestic treated water as ballast water of a vessel, a match is made between information on domestic treated water to be supplied and information on demanded domestic treated water. The matching result is sent to ship owners of vessels that transport the domestic treated water. Each ship owner decides and offers a sale price and a transport water quantity to demanders. If a transaction is determined, the information on the domestic treated water to be supplied and the information on the demanded domestic treated water are corrected on the basis of the transport water quantity to make a match again. Thus embodied is a method of supporting a transaction of domestic treated water.

Water to be treated is passed through a membrane (net), magnetic floc positioned in a portion below a level of the water to be treated is deposited to a surface of the membrane, and the surface of the membrane with the magnetic floc deposited is moved to an atmospheric portion above the level of the water to be treated. In the atmospheric portion, excess water from the magnetic floc flows downward due to gravity to concentrate the magnetic floc. A permanent magnet is located near a position to which the membrane surface with the magnetic floc deposited thereon moves. There are further provided between the magnet and the membrane surface a moving body (shell) formed by a non-magnetic material, a spatula for scraping the magnetic floc from the moving body, and a sludge vessel in which a released magnetic floc is recovered.

Coolant (3) whose boiling point is higher than the temperature of cooled SQUID elements (2) as cooled objects is poured into an inner container (37) for containing SQUID elements. The SQUID elements (2) are soaked in the coolant (3). Before the inner container (37) for containing SQUID elements is used, the coolant (3) is cooled and solidified by a refrigerator (7).
