Ballast water is the water carried by ships to maintain a specific balance when they are loaded with cargo or when they are not carrying any cargo.

 The amount of ballast water carried by a ship varies depending on its size. During the loading process, ballast water is also discharged into the ocean.

 This helps achieve balance and a high volume of cargo loading. During the unloading process, the ship pumps out the ballast water. 

The water pumped out contains a large number of microorganisms and organisms. These organisms are transported to distant places by the water tanks of cargo ships. 

The ecosystem at the unloading location is very different from the ecosystem that the organisms in the tanks are accustomed to. 

Therefore, they encounter adaptation problems in the new environment. This leads to the disruption of the marine ecological balance.

To prevent the natural balance in the ocean from being disrupted, various measures have been taken. According to these measures, 

the proportion of organisms that ships can carry in ballast water has been determined. 

These decisions are implemented through the enforcement of various orders.

The use of marine transportation for transportation activities is increasing day by day. Because it can transport large quantities of goods at once, 

it has become the most common mode of transportation in the world. Therefore, the use of ballast water is also increasing, posing a serious threat to the global environment. 

To reduce the organisms contained in ballast water, various management and purification systems need to be used. 

Many companies have prepared various treatment methods for this purpose. The increasingly developed transportation and logistics systems also contribute to the establishment

 of ballast water purification systems in the economic market.

The use of ultraviolet light is one of the methods for balancing soil management. Ultraviolet light is light with a wavelength between 100 and 400 nanometers. 

Ultraviolet light is divided into three different parts: *UV-A (315 – 400 nm)

There are three classifications of ultraviolet light: ultraviolet-B (280 – 315 nm), ultraviolet-C (200 – 220 nm), and ultraviolet-A. 

The effects of these three types on living organisms are different. These effects have been studied by scientists. For instance, 

Arnolf's research demonstrated that when exposed to ultraviolet light with a wavelength of 253.7 nm, the photosynthetic efficiency of plants would decline.

The effects of ultraviolet-A and -B on organisms are more developed in relation to ultraviolet-C light. In the future, the impact of ultraviolet-B will also be studied.

There are two ways to use ultraviolet light in conjunction with coagulants. One is to add ultraviolet beams to the water during the dosing process, 

which will cause damage to the DNA of microorganisms in the environment. This damage can prevent unwanted organisms from multiplying in the coagulant. 

The other method is to use a stronger ultraviolet beam during the dosing of the coagulant. This beam can ensure the elimination of all organisms in the environment.

Using sand as ballast has several advantages. These advantages can be ranked as follows:

- The FIVER UV system will automatically start when set up by a specific person. It does not wait for any user command. It is systematic.

- There are no corrosion issues with the system.

- No harmful materials need to be stored or dangerous chemicals present in the environment for the system to operate. From this perspective, it is economical.

- There is no need to adjust the dosage. There is no worry about over-dosing or under-dosing.

- It has an impact on all organisms. There are no organisms resistant to ultraviolet light.

- It is a system with no significant impact.

By using FIVER Ballast UV Water Treatment System, the damage to the ecological balance caused by ballast water can be prevented. 

Ultraviolet irradiation is one of the most effective disinfection methods. The cost of the disinfection system using ultraviolet light varies according to the dosage. 

The most important point to note is that the ultraviolet system requires regular maintenance after installation. 

The ultraviolet lamps used may lose their effectiveness after a period of time. Control and maintenance are very important.
