Welysis - Sodium Hypochlorite Plants
Sodium hypochlorite is primarily used for water purification due to its strong fungicidal and bactericidal properties. It is also widely applied in bleaching textile fibers and disinfecting environments like swimming pools. Given its escalating use and market growth, local production via electrolysis plants is becoming essential due to handling risks and transportation restrictions. The production process ensures quality by maintaining sodium hypochlorite concentration between 12-15% active chlorine, limiting sodium hydroxide and sodium chlorate levels to prevent unwanted reactions, and controlling impurities like iron and nickel to preserve product integrity. The production plants incorporate advanced technologies for process control, waste minimization, and by-product recycling, enhancing safety and efficiency. These plants also comply with rigorous international safety regulations to protect workers and the environment.
Our electrolysis plants produce sodium hypochlorite with the chemical formula: NaCIO, a strong oxidizing chemical compound.
Our electrolysis plants produce sodium hypochlorite with the chemical formula: NaCIO, a strong oxidizing chemical compound. A sodium hypochlorite solution of between 10% and 17% can be obtained by diluting it in water to different percentages depending on its intended use. Chlorine gas (Cl2) is produced in the membrane electrolysers, which is then absorbed with caustic soda in the Chlorine Absorption unit, resulting in the production of sodium hypochlorite.
Due to its fungicidal and bactericidal properties, the main application of sodium hypochlorite is in the purification of water for human consumption, although it is also used as a bleach for textile fibres, and in other sectors for the cleaning and disinfection of swimming pools and other environments.
Despite its use becoming more and more widespread and being an expanding market, its handling and delivery entail risks, and even its transport is restricted in some countries. Consequently there is a growing demand for it to be produced locally in electrolysis plants.
