摘要:
A ballast water treatment apparatus includes a filter that is cylindrically formed so as to surround an axis, a case that includes an outer cylindrical portion that is disposed so as to surround the filter, a rotation mechanism that rotates the filter around the axis, an untreated water nozzle that ejects untreated water to a filter-surrounding region that is defined by an outer peripheral surface of the filter and the outer cylindrical portion, a cleaning water nozzle that ejects cleaning water toward the outer peripheral surface of the filter, a filtered water channel through which filtered water that has passed through the filter flows from a region inside the filter to outside of the case, and a discharge channel through which discharged water that has not passed through the filter is discharged from the filter-surrounding region to outside of the case.
摘要:
A vertically elongate and oriented container (1) of wire cloth material contains a vertically oriented nozzle assembly (2), which sprays a fiber suspension against the inner wall of the container. The nozzle assembly is revolved around the axis of the container and is displaced backwards and forwards vertically so that the suspension sprays, which in the direction radially outward widen against the shell wall of the container (1) afford a cleaning effect in respect of deposited fibers on the inner wall of the container (1) at the same time as the liquid of the suspension efficiently is separated through the container wall in order to then be collected in a housing (9) surrounding the container (1).

A filter (1) disposed as a cylinder around an axis line, and provided to be rotatable around the axis line, a treated water nozzle (2) for emitting treated water toward an outer circumferential surface of the filter (1), a case (3) provided to surround the filter (1), and including an outer cylindrical portion (31) having a nozzle opening (21) of the treated water nozzle (2) therein, a filtered water flow path (7) for guiding filtered water that has been transmitted through the filter (1) to outside of the case (3) from within the cylinder of the filter (1), and a discharge flow path (8) for discharging discharged water that was not filtered through the filter (1) to the outside of the case (3) are provided. Consequently, a device of treating ballast water for a ship that can be mounted on a ship and can efficiently kill or inactivate microbes in ballast water discharged from or loaded into the ship, and a treatment method thereof can be provided.

摘要:
A self-cleaning system for use with a filter having a fluid inlet station, including (a) a manifold mountable at least for reciprocation along an axis with respect to said filter and comprising at least one suction opening adapted to be in proximity to said station and connectable to a suitable suction source for enabling foreign material to be removed from said filter when said system is installed and in operation with respect to said filter; (b) fluid powered motive means for propelling said manifold along said axis; and (c) a reciprocating mechanism for alternately changing the direction of motion of said manifold along said axis.
摘要:
Described is a continuous liquid filtering apparatus having a preliminary filtering chamber 9, a filtering chamber 3, a filtered liquid chamber 12, and an electromechanical cleaning system. In operation, after entering inlet 1, liquid passes through coarse screen 2 into the filtering chamber 3. The liquid then passes through a multi-layer sintered filtering element 4 before exiting the apparatus through the outlet 6. The electromechanical cleaning system includes a hollow connector unit 10 having dirt suctioning members 5 and spraying nozzles 11 for cleaning the sintered filter element. The cleaning system is activated whenever the liquid differential pressure exceeds a predetermined valve indicating that the cylindrical filter requires a cleaning treatment. The spraying nozzles 11 are in fluid communication with the filtered liquid chamber 12 via booster pump 13.
摘要:
Improved self-cleaning filter, comprised of a casing (1) with an entry (2) for water towards an encircling chamber (5), a filtering element based on a plurality of grooved disks (10), an axial passage (14) in the breast of these disks and an axial exit (9) for clean water. The filtering element (10) is completed in its lower end by a flap (11) that closes the axial passage (14) in the backward movement of water during cleaning, forcing it to go through side collectors (15) unaffected by the flap (11) and in which established are windows (16) for the exit of water, obliquely oriented in a side direction to make the disks (10) rotate during cleaning, also oblique in a vertical direction to take advantage of the separation between the disks (10) and distributed helically (15), the support tower (6) of these disks completed in a retractile rammer (21).
