Cathodic Protectionis a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects protected metal to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal.
The commons applications are
Water treatment could be applied for various fields, our anodes are currently used for Sodium Hypochlorite and Electrolysis of water.
Sodium hypochlorite (NaOCl) is a compound that can be effectively used for water purification. It is used on a large scale for surface purification, bleaching, odor removal and water disinfection.
Sodium hypochlorite is applied in swimming pools for water disinfection and oxidation. It has the advantage that microorganisms cannot build up any resistance to it. Sodium hypochlorite is effective against Legionella bacteria and bio film, in which Legionella bacteria can multiply.
It can be also applied in sanitary wastewater and industrial wastewater, etc.
Hydrometallurgy is a method for obtaining metals from their ores.It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores,concentrates, and recycled or residual materials.
