Abstract: A fluid treatment method reduces a concentration of a first component included in a fluid-to-be-treated. A fluid treatment apparatus reduces a concentration of a first component included in a fluid-to-be-treated. A concentration of a second component differing from the first component is reduced in the fluid-to-be-treated in order to obtain a first fluid. The first fluid passes through at least part of an adsorption unit in order to obtain a second fluid. The adsorption unit is capable of adsorbing both the first component and the second component and has at least an ability to adsorb the first component that is temperature dependent. A third fluid pass through a portion of the adsorption unit through which the first fluid has passed. The third fluid has a concentration of the second component that is lower than in the fluid-to-be-treated and a temperature that is higher than the fluid-to-be-treated.

Abstract: A current passing device passes current through bodies. The current passing device includes a first current receiving element having an electrical resistance, a second current receiving element having a contact resistance greater than the electrical resistance of the first current receiving element in a state in which the second current receiving element has been brought into direct contact with the first current receiving element without pressing the second current receiving element, a pressing mechanism arranged to press the first current receiving element and the second current receiving element closer together, and an electrically conductive intervening member disposed between the first current receiving element and the second current receiving element. The intervening member has a degree of deformation greater than degrees of deformation of both the first and second current receiving elements in a case where the intervening member has been pressed due to the pressing mechanism.

Abstract: An adsorbing molded body is configured to be subjected to ohmic heating or electromagnetic wave heating. The adsorbing molded body includes an electrically conductive powder adsorbent, an insulating powder adsorbent, and an inorganic binder that binds the powder adsorbents together. An adsorption recovery treatment apparatus includes the adsorbing molded body and a heating unit to heat the adsorbing molded body, preferably ohmically or using electromagnetic waves. An adsorbate desorbing method includes desorbing an adsorbate, which the adsorbing molded body has adsorbed, from the adsorbing molded body by heating the adsorbing molded body, preferably ohmically or using electromagnetic waves.
