PLANTS FOR THE PRODUCTION OF SODIUM HYPOCHLORITE BY ELECTROLYSIS
Chlor-alkali plants for sodium hypochlorite generation
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.

FAQ ABOUT OUR Chlor-alkali plants for sodium hypochlorite generation
All the information in detail
How do we ensure quality and safety in the production of sodium hypochlorite?
How do we ensure quality and safety in the production of sodium hypochlorite?
Quality and safety in the production of sodium hypochlorite are guaranteed by strict composition and purity controls. We ensure that the sodium hypochlorite content remains within the optimum range of 12-15% active chlorine, with a maximum of 6.0 gpl sodium hydroxide and 3.0 gpl sodium chlorate to avoid adverse reactions. In addition, we maintain minimum levels of impurities such as iron (max. 0.5 ppm) and nickel (max. 0.05 ppm) to prevent product degradation and ensure product safety in industrial applications. With regard to safety, we adopt the safety measures recommended in the safety data sheet to protect operators and the environment when handling the product.
What are the industrial applications of the sodium hypochlorite produced in our facilities?
The sodium hypochlorite produced in our facilities has wide sanitary (industrial) applications thanks to its disinfectant properties. It is mainly used in water purification, swimming pool treatment, and in the manufacture of bleaches and other biocides. Its high concentration of active chlorine makes it especially effective in the elimination of pathogens and in large-scale cleaning and sanitising processes, meeting the safety and efficacy standards required for these critical uses.
What technological innovations do we incorporate in the construction of our plants?
In the construction of our sodium hypochlorite production plants, we incorporate technological innovations that optimise the efficiency and safety of the production process. These innovations include advanced process control systems that monitor and adjust in real time the reaction conditions to maintain product quality within the desired parameters, acting on pH, temperatures, conductivity, operational pressures, etc.. We also implement waste minimisation and by-product recycling technologies to reduce the environmental impact of our operations. The integration of state-of-the-art safety systems ensures the protection of our workers and the environment, in compliance with the strictest international regulations.
These detailed technical responses reflect our commitment to excellence in sodium hypochlorite production, ensuring high quality and safe products for critical industrial applications.
