Those engaged in shipping have to bear great responsibility every time they leave the port. First of all, they are responsible for fulfilling their duties, transporting and delivering goods for customers all over the world. Completing this task is very important, requiring every part of the shipping company to consider the impact of its ships on the environment. Global shipping corridors connect humans on an unprecedented scale, but they also endanger various ecosystems around the world. B. Pollution by microorganisms moving in the ship’s ballast water or infiltration of the marine ecology of the new area, causing immeasurable damage to the area.
• This is how ballast water treatment works. It should be noted that most BWTS use a combination of filtration and secondary disinfection steps for processing. Chemical disinfection. Many BWMS use biocides as a disinfection step. Microorganisms in ballast water. Approximately half of the plants use fungicides. The main disadvantage is that the treated water may have to be neutralized or detoxified before final ballasting.
⁃ Ultraviolet treatment method -
Ultraviolet ballast water treatment methods include ultraviolet lamps surrounding a chamber through which ballast water can pass. Ultraviolet lamps (amalgam lamps) emit ultraviolet rays that attack the DNA of organisms, making them harmless and preventing them from reproducing. This method is successfully used to filter water worldwide and is effective for a large number of organisms.
⁃ Gas purification process -
In the analysis of ballast water, inert gas is introduced into the ballast water through the venturi tube to reduce the oxygen groups in the water and neutralize the ballast water. The oxygen inert gas solution is less than 0.1%, which is much lower than the inert gas used by tankers, less than 5%. In addition, some systems use ozone, which has a powerful disinfection effect. During ballast water discharge, these treatments may require sterilization techniques or standard water management.
⁃ Marine Wipers -
Best Features You need to find superior, better performing marine wipers for all uses. This includes the type of boat and the environment in which the device will be used during engine scaling, and the type of windshield wiper.
⁃ Deoxygenation-
It is the same as bactericide, deoxygenation will kill all the organisms in the ballast water. The ballast water purification system pumps inert gas (such as nitrogen) into the tank or ballast water stream to suffocate organisms. This system may be effective, but it is important to note that this process takes two to four days, and the tank must be isolated from atmospheric oxygen. Hypoxia is not recommended for short-distance transportation
⁃ Electrolysis method -
The absorption of ballast water passes through the filter and removes huge aquatic organisms and debris over 50 microns. The cavitation device deforms the cell membrane of the organism, and the purified nitrogen on the machine combines with the hydroxide ions generated during electrolysis for disinfection and destruction. Aquatic organisms and fungi.
• Your ballast water treatment system.
The type of ballast water treatment system your ship needs depends on size, available space, budget, and other factors. However, your boat (any boat) will almost certainly benefit from ballast. Water purification system with filter safety filter. Filtersafe provides tailor-made solutions that perfectly complement any ballast water treatment system. First of all, our patented filter cloth can not only prevent most zooplankton, phytoplankton and sediment from entering the ballast water tank. Wastewater has been shown to filter up to 25 microns, and less post-treatment is required to disinfect the water, which means that BWTS owners save money by reducing energy consumption and using disinfectants.
• Why is ballast water treatment needed?
Ballast water treatment aims to eliminate invasive marine species. Ballast water is described as "one of the main ways to introduce non-native marine species". At the new port of call, they risk introducing alien species into the waters around the new area, from small fish to microorganisms. This may lead to a series of destructive effects related to microbial exposure to invasive marine species, degradation of habitat quality and other threats, which may eventually damage the fisheries and even protected species in the area.
