OceanGuard® BWMS is developed by Headway Technology Co., Ltd. together with leading universities in China. OceanGuard® BWMS adopts Advanced Electrocatalysis Oxidation Process (AEOP) to kill microbes, bacteria, viruses, and dormant ovum in water by using special semiconductor materials under electron excitation and the hydroxyl radicals (·OH) formed by water molecules. Hydroxyl radical (·OH) produced in AEOP is one of the most active substances with very strong oxidizability. It can have different kinds of chemical reactions with almost all biological macromolecules, microorganisms, and other organic pollutants instantaneously.
Besides, it has an extremely fast reaction rate and strong negative charge electron affinities. The end products of the reaction are CO2, H2O, and traces of inorganic salt without any hazardous residuals. Therefore, the treated water can be discharged out of the board without any pollution. The chemical reaction which involves hydroxyl radical is a free radical reaction, and it is extremely fast. Generally, the reaction rate with organics is over 109 L/ (mol.s).
The Electrocatalysis Unit is able to produce large numbers of hydroxyl radicals and other highly active oxidizing substances to kill all organisms in ballast water within several nanoseconds. The whole sterilization process is completed inside the EUT Unit. During the treatment process, the Ultrasound Unit can clean the surface of the Electrocatalysis Unit regularly to keep the long-term treatment effectiveness of the electrocatalysis material.
