Ballast Water Treatment System – Electrolysis Method
The ballast water entering the pipe through the ballast pump passes through the electrolysis chamber (ECU) and is directly sterilized by electrical sterilization. Disinfected ship ballast water flows into the ballast tank, and the remaining hypochlorous acid completely prevents microbes from regenerating and breeding.
The ballast water in the ballast tank minimizes the impact on the marine environment by neutralizing the remaining TRO before discharging the ballast water to the sea. Unlike ballasting, in the case of de-ballasting, it is discharged directly from the ship without going through the ECU.
ECS is the most effective disinfection device to completely prevent the propagation of residual microorganisms, as the ballast water passes through the electrolysis chamber (ECU) and electrical sterilization occurs. BWTS proprietary electrolysis technology has achieved more complete sterilization through the following three steps.
Potential difference(Electric potential)
Potential difference refers to the force that promotes oxidation, which occurs at the anode of the electrolyte and decreases at the cathode. Pulling oxide material through the action Grab your e-going away from the cell wall of the microorganism to make the cells become unstable, resulting in the sterilization will act by destroying the cell wall of the microorganism.
Seawater having various kinds of salinity is broken by the electrochemical reaction occurring on the electrode surface. The OH Radical generated by electrolysis is instantaneously generated for a very short period of a billionth of a second. This is only a phenomenon caused by the exchange of ions, but at the same time it removes bacteria and aquatic microorganisms.
Electrochemical oxidation(Electrochemical oxidation)
The electrochemical oxidizing effect is a phenomenon in which the surface of the electrode formed by electrolysis is composed of hypochlorous acid (HOCI), hypochlorite ion (OCI), hypobromous acid (HOBr), hypobromous acid ion (OBr ) , And hydrogen peroxide (H₂O₂) oxidizer to remove microorganisms in water. Hypochlorous acid and hypochlorite ions are present in water of 6 to 9 pH, and the ratio of each kind varies depending on pH and temperature. Hypochlorous acid is equivalent to hypochlorous acid over a period of about 25 to 30 minutes, compared to destroying microorganisms with a bactericidal ability as effective as a biocide for a short period of about 2 seconds. Similarly, hypoabromic acid and hypoabromic acid ions are similarly formed and involved in biological removal. Since hydrogen peroxide is also used as a disinfectant for medical products or as an oxidizing agent for industrial use, these substances remain in the ballast water and help to prevent the regeneration and propagation of microorganisms and bacteria.
