Abstract: Provided are a novel method and device for treating a liquid that can be utilized for treating ballast water used in ships, etc. The method and device for treating a liquid provided herein allow aquatic organisms contained in a liquid to be sufficiently inactivated or separated by being configured in such a manner as to, in supplying the liquid containing aquatic organisms, carry out at least one of an aquatic organism-inactivating treatment and a physical treatment using a centrifugal force and then store the liquid in a storage means, and in discharging the liquid thus stored, determine whether or not the aquatic organism-inactivating treatment is required, carry out the treatment based on the determination, and carry out the physical treatment using a centrifugal force.

Abstract: When a plurality of cyclones are used as a separation device of a water treatment device, there have been as many lower liquid containers as the number of cyclones, resulting in high cost. Provided is a centrifugal solid-liquid separation device including: a plurality of cyclones respectively having at least a liquid inlet, a liquid outlet, and a lower liquid port; and a lower liquid container communicating with the respective lower liquid ports of the plurality of cyclones via pipes, arranged below the plurality of cyclones, and having a drain hole in its bottom side. The lower liquid container includes a space forming portion above lower opening ends of the pipes. Also provided is a water treatment device using this centrifugal solid-liquid separation device.

Abstract: To provide a voltage-type device for killing microorganisms in which a microorganism killing effect is high and scale is less likely to clog up through holes in electrodes. The device for killing microorganisms includes: a main body which a liquid to be treated flows in at one end and flows out at the other end; opposed electrodes that are arranged in the main body in parallel with a flow of the liquid to be treated and have mutually-opposed through holes; and a voltage source of which an anode is connected to one of the opposed electrodes and a cathode is connected to the other of them. When a straightened liquid to be treated is passed through the device for killing microorganisms, a stirring action is produced between the opposed electrodes, whereby hypochlorous acid can be diffused throughout the entire device and a high killing effect can be obtained.

Abstract: A novel method and device for treating a liquid are provided, wherein a concentrated liquid recovered using a centrifugal separation method can be utilized as ballast water. The present disclosure relates to a method for treating a liquid that comprises a storage step including carrying out a physical treatment using a centrifugal force with respect to a supply liquid to be supplied to a storage means located inside a housing, wherein the method comprises carrying out an aquatic organism-inactivating treatment contained in a concentrated liquid obtained by the physical treatment using a centrifugal force and supplying to the storage means the concentrated liquid subjected to the aquatic organism-inactivating treatment.

Abstract: A control method for drying clothes is disclosed. The method finds a difference in surface temperature between clothes catching air blow and the same clothes catching no air blow, and then determines a degree of dryness in the clothes based on the difference. Based on the degree of dryness, the method determines at what time heating should start.
