Seawater electro-chlorination is a process that uses an electric current to convert seawater into a powerful disinfectant called sodium hypochlorite. This sanitizer is commonly used in marine applications to treat seawater before it enters a ship’s ballast tanks, cooling systems and other equipment. During electro-chlorination, seawater is pumped through an electrolytic cell containing electrodes made of titanium or other non-corrosive materials. When a direct current is applied to these electrodes, it causes a reaction that converts salt and seawater into sodium hypochlorite and other byproducts. Sodium hypochlorite is a strong oxidizing agent that is effective in killing bacteria, viruses and other organisms that may contaminate a ship’s ballast or cooling systems. It is also used to sanitize seawater before it is discharged back into the ocean. Seawater electro-chlorination is more efficient and requires less maintenance than traditional chemical treatments. It also produces no harmful by-products, avoiding the need to transport and store hazardous chemicals on board.

Overall, seawater electro-chlorination is an important tool for keeping marine systems clean and safe and protecting the environment from harmful pollutants.
