Electrochlorination

Electrochlorination is a process of water treatment that involves the electrolysis of water to produce chlorine gas, which is then used for disinfection purposes. It is commonly used for water purification, chlorination of swimming pools, and disinfecting sea water used for cooling at power stations or on large ships. During the process, water molecules are decomposed into hydrogen and hydroxide ions at the cathode, and aqueous chloride ions are combined into chlorine gas at the anode.From: Modern Ceramic Engineering [2019], Modeling Hydrogen Explosion in Level 1 PSA [2021]

Electrochlorination is used for water purification, chlorination of swimming pools, and disinfecting sea water used for cooling at power stations or on large ships. A small electric current applied through a ceramic electrode causes decomposition of water and the dissolved sodium chloride adjacent to the electrode to yield hypochlorous and/or hypochlorite ions. These ions have strong disinfecting capabilities. The chloralkali process involves the electrolysis of NaCl to produce chlorine, hydrogen, hypochlorite, and NaOH (caustic soda). Currently, electrodes for the chloralkali process are graphite- or titanium-coated, ruthenium-doped TiO2.

The treatment of seawater by electrochlorination in the pumping station consists of electrolysis of seawater: Water molecules are decomposed into and ions at the cathode, and aqueous ions are combined into gas at the anode. The typical pure hydrogen flow rate produced by the process may reach several tens of cubic meters per hour.
