Abstract

Provided is a ballast water treatment apparatus capable of properly clearing away foreign matter settling at the bottom of a filter. The ballast water treatment apparatus is equipped with a filter formed to be cylindrical, a water discharge pipe part configured at the position aligned at a central shaft of the filter and internally equipped with a space for water circulation, a nozzle part and a bottom nozzle part. The base end side of the nozzle part is connected to the water discharge pipe part and the front-end side is configured at the position closing to or abutting against the inner peripheral surface of the filter and opened. Water can circulate from the front end to the base end side. The bottom nozzle part is arranged at the lower part of the filter. The front-end side of the bottom nozzle part is opened towards the bottom of the filter. Water can circulate from the front-end side to the water discharge pipe part.

Description

technical field [0001] The invention relates to a ballast water treatment device with a filter. Background technique [0002] In the past, in ships such as cruise ships, after unloading the loaded crude oil, etc., when sailing to the destination again, in order to balance the ship while sailing, the ship storage in the ballast tank of the ship is called ballast. water of water. Ballast water is basically taken at the port of discharge and discharged at the port of loading. Therefore, if these locations are different, plankton and bacteria-like microorganisms contained in ballast water move around the world. Therefore, if ballast water is discharged at a discharge port in a sea area different from the discharge port, microorganisms in a sea area different from the port are released, and the ecosystem of the sea area may be destroyed. [0003] In order to remove foreign matter such as microorganisms, sand, and garbage contained in ballast water, a ballast water treatment de...
