Description

Plasma ballast water treatment device for ships having a module type assembly

The present invention relates to a plasma ballast water treatment device for ships having a module type assembly, and more particularly, to a module type assembly that is provided in a module type to enable ballast water treatment of various capacities across small and medium to large sized ships. It relates to a plasma ballast water treatment device for ships equipped with.

Due to the characteristics of ships that move over long distances on the sea, the water treatment process performed within the ship has a potential risk of causing environmental pollution depending on the quality of treated water and at the same time disturbing the ecosystem through intercontinental movement.

Water resources used or discharged from ships can be largely classified into the following three categories.

That is, ballast water, water supply in ships through fresh water generators, washing water used in scrubbers, which are air pollution reduction devices, and the like.

Among them, ballast water refers to the water filled in the ballast water storage space in a ship or discharged to the sea to set the ship's level and center of gravity.

When a heavy load is loaded on a ship, it increases the buoyancy by increasing the specific gravity of air, and increases the specific gravity of ballast water using seawater in a light ship that has unloaded a load, thereby reducing buoyancy and enhancing stability.

However, seawater filled for ballast water at each coast can flow into ships without being treated and serve as a medium for spreading alien species.

In particular, due to the recent development of shipbuilding and navigation technology, ship operation time has been shortened, which allows most ships to sail in various areas and at the same time increases the survivability of microorganisms in ballast water, such as organisms or pathogens in specific sea areas. It causes side effects that disturb the environment and ecosystem of other sea areas transported through the ballast water in the ship.

It is estimated that more than 10 billion tons of ballast water is moved around the world every year, and the cross-border movement of species in ballast water has been shown to cause great damage to other commercial activities, resources, and coastal industries as well as ecosystem disturbance.

As problems with ballast water continued to appear, in 1992 the United Nations conference on environmental and development (UNCED) made a mandatory provision regarding the discharge of ballast water to prevent the spread of non-native organisms. A catalog was requested to the international maritime organization (IMO).

IMO requested a discussion on the ballast water management provisions to its marine environmental protection committee (MEPC), and at an IMO diplomatic meeting in February 2004, “International standards for the control and management of ballast water and sediment Convention” was adopted, and on September 8, 2016, the requirements for publication of the Convention were met, and the Convention entered into force on September 8, 2017.

This agreement on ballast water was applied after being classified into D-1, which is capable of exchanging ballast water in waters more than 200 miles away, and D-2, which is equipped with ballast water treatment facilities, at the time of the initial proposal. Since then, all have been changed to D-2.

Also, in the United States, each state intervenes in ballast water management on a policy basis, and in particular, California manages discharge of ballast water with stronger standards than IMO standards, such as collection of alien species control funds.

It must be discharged by satisfying the IMO D-2 regulations and the effluent standard after ballast water treatment established in California.

In view of the above, devices for sterilizing ballast water in various ways, including Registered Patent No. 10-0797186 (hereinafter referred to as prior art), are known and are being researched and developed.

However, since existing sterilization devices, including the prior art, adopt an electrolysis method, there is a problem of extreme power consumption in the case of large ships.

Therefore, it is urgent to develop an apparatus capable of reducing power consumption and performing ballast water treatment of various capacities across small and medium-sized ships.
