Description

{Ballast Water Plant}

The present invention relates to a ballast water ballast water ballast water treatment system, and more particularly, to a ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water ballast water It is an offshore plant. In order to reduce the time for ballasting, pumps are installed in offshore plants. Ballasting is a method of cleaning seawater using electrolysis, which is the principle of electrochemical oxidation (electrochemical oxidation).

Ship ballast water is water that holds the center of gravity of the left or right or up and down of the ship. When a large cargo ship is operated with all cargoes empty, the center of gravity is raised and the fuel efficiency drops. In order to correct this, the ballast water is filled in the vessel.

However, the ballast water contains a large amount of heavy metals and foreign aquatic creatures, which are disturbing the ecosystem and destruction is becoming a major cause of marine pollution.

Therefore, the installation of ballast water discharge treatment facilities, which catch the center of gravity of vessels such as large cargo ships, became mandatory in 2010. Ships constructed before 2010 should be installed with treatment facilities by 2016.

1. Ballast water contains a large amount of heavy metals and aquatic organisms, which are the main cause of marine pollution due to disturbance & destruction of ecosystem.

2. When ballast water treatment system is installed on a ship, it has a problem of high loading cost and deterioration of structure of ship and decrease of cargo load.

3. In order to install the treatment equipment on the shore without installing it on the ship, there must be a port with a space where the ship can berth.

4. The vessel to be ballasted is not one or two vessels at the same time.

5. Because ballast capacity is large, ballasting takes a long time.

1. There are various treatment methods such as residual chlorine meter, gas-liquid separator, flow control valve, but we chose electrolysis method.

Electrochemical oxidation is as follows.

Step 1: At the positive (+) pole of the electrolyte, pull the electrons away from the cell wall of the microorganism and make the cell unstable. This destroys the cell walls of the microorganisms and disinfects them.

Step 2: Seawater having various kinds of salinity is broken by the electrochemical reaction occurring on the electrode surface. The OH radicals generated by electrolysis are produced and disappeared within a very short period of a billionth of a second. This radical is only a phenomenon caused by the exchange of ions, but at the same time removes bacteria and aquatic microorganisms.

Step 3: Remove microorganisms in the water with HClO, OCI-, HOBr, Obr-, O, HO oxidizing agents formed on the electrode surface.

2. If the ballast water treatment system is not installed on the ship, it will save the drying cost and the space will be increased accordingly, so the cargo load will increase.

3. Build a coastal fixed offshore plant that does not land but builds a new space on land.

4. The number of pumps that will connect the ship and offshore plant is determined by the installation area.

5. Install pump on offshore plant to reduce ballast time.

6. Ensure that the flow of the algae smoothly sinks below the seawater.

It is less costly to install a ballast water plant than to install a ballast treatment system on existing & new ships (saving drying cost).

Foreign currency will flow due to the sewage treatment of overseas vessels.

By checking the ballast water treatment, you can prevent illegal discharge of sewage into the sea.

There is a synergy effect on the national image as it is given to the Greenpeace movement on an international level.

The marine species contained in Ballast Water can prevent destruction of native and other indigenous ecosystems.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 6, the present invention is basically a fixed coastal offshore plant. In order to prevent environmental pollution caused by ballast water, a ballast water treatment system is not installed on a ship but is made into an offshore plant.

Here, in order to smooth the flow of the algae and secure the stability, a hole is secured in the part sinking below the seawater, and a circular structure that allows the ship to beret as much as possible is provided. In order to reduce the filling time of the ballast water, Is installed in an offshore plant, and an apparatus for treating ballast water is characterized by using electrolysis.

Claims (5)

In order to increase the loading capacity of ships, marine structures made by connecting ship equipments to marine plants Marine structures that are circular in shape so that many ships can berth. An offshore structure with openings on both sides of the sinking area below the seawater in order to smooth the flow of the algae and ensure stability. An offshore structure with a pump installed on an offshore plant to reduce the time required to fill the vessel with ballasting water. An offshore structure that protects ecosystems and the environment by destroying the cell walls of microorganisms using electrolysis.
