    Abstract: A ballast water treatment apparatus (100) is provided. The ballast water treatment apparatus includes a ballast water transport line (107) configured to transport a ballast water main stream, a plasma generation device (200) configured to generate an activated gas from a feed gas; and a mixing device (225). The plasma generation device (200) includes a feed gas inlet (205) for a feed gas, a first electrode (202) and a second electrode (204), for activating the feed gas by an electric discharge between the first electrode (202) and the second electrode (204) thereby generating the activated gas, a cooling fluid passage (206) for cooling the plasma generation device (200), the cooling fluid passage having a cooling fluid inlet (203) and a cooling fluid outlet (207), the cooling fluid passage (206) being fed with a cooling fluid, and a combining section being configured to combine the activated gas with the cooling fluid from the cooling fluid outlet (207) to generate an activated fluid product. The mixing device (225) is configured to mix the activated fluid product and the ballast water main stream.

    Abstract: A water treatment device (100) comprising a first hydrocyclone (102) and a biocidal fluid injector (120) is described. The first hydrocyclone (102) has an internal space (104), a water inlet (106) for supplying water into the internal space (104), a base outlet (108) for discharging at least a part of the water, and an apex outlet (112). The biocidal fluid injector (120) is configured to inject a biocidal fluid into the internal space (104) for eliminating organisms present in the water. The biocidal fluid injector (120) is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone (102).

    Abstract: A ballast water treatment apparatus (100) and a ballast water treatment system (1) having a ballast water treatment apparatus (100) are provided. The ballast water treatment apparatus (100) includes a ballast water transport line (10) configured to transport ballast water between a first location (A) and a second location (B), the transported ballast water being passed through at least one injector (20), and a plasma generation device (30) configured to be fed with a feed gas optionally comprising oxygen, and configured to generate a feed gas plasma (35) by a streamer type discharge in a discharge area (36) to provide a treated gas at a treated- gas outlet (37). The injector (20) comprises a liquid passage (21) having an area (22) constructed such as to increase a velocity of the passed-through water in a region (26) of increased velocity, and an injector gas inlet (25) provided in the region (26) of increased velocity. The treated-gas outlet (37) is in gaseous connection with the injector gas inlet (25).

    Abstract: The present disclosure provides a gas-insulated high or medium voltage circuit breaker (100) including a first arcing contact (101) and a second arcing contact (103), wherein at least one of the two arcing contacts is axially movable including a first and a second state of motion along a switching axis (140), wherein during a breaking operation, an arc between the first arcing contact and the second arcing contact is formed in an arcing region; a nozzle (110) including a channel (112) directed to the arcing region, for blowing an arc-extinguishing gas to the arcing region during the breaking operation; a diffuser adjacent to the nozzle, for transporting the gas from the arcing region to a region downstream of the diffuser; a buffer volume (170) directly downstream of the diffuser, and an enclosure (120) substantially surrounding the buffer volume (170) circumferentially, wherein the enclosure includes an inner enclosure portion (123) and a coaxially arranged outer enclosure portion (121), wherein at least one of the inner portion and the outer portion is movable relative to the other one; and a first aperture (127) provided on a surface of the inner enclosure portion and a second aperture (125) provided on a surface of the outer enclosure portion, such that a through opening is providable through the enclosure (120), wherein in the first state of motion during a breaking operation the through opening is blocked, as to prevent the gas from being released from the buffer volume (170) to a volume outside (180) of the enclosure (120); and in the second state of motion, the first aperture (127) and the second aperture (125) overlap, such that the overlap of the first aperture and the second aperture provides the through opening for the gas to be partially released from the buffer volume (170) to the volume outside (180) of the enclosure.

    Abstract: Gas-insulated high voltage puffer breaker comprising a puffer unit with a movable piston running in a puffer cylinder and delimiting a puffer volume. A piston and a first contact member are attached to a piston stem. A piston and a first contact member are attached to a piston stem. An electric arc is extinguishable in an arcing zone when the first contact member moves from a first position to a second position. The puffer volume is fluidly connected to a gas nozzle by a gas channel such that the puffer volume comprises the gas channel as well as a portion of the puffer cylinder. The gas channel is provided radially outside of the puffer cylinder between a puffer cylinder wall delimiting the puffer cylinder and a wall structure of the puffer unit.
