Sodium Hypochlorite

PLANTS FOR THE PRODUCTION OF SODIUM HYPOCHLORITE BY ELECTROLYSIS

Our electrolysis plants produce sodium hypochlorite with the chemical formula: NaCIO, a strongly oxidizing chemical compound.

Our electrolysis plants produce sodium hypochlorite with the chemical formula: NaCIO, a strongly oxidizing chemical compound.

It is diluted in water at different percentages depending on its use, and a sodium hypochlorite solution of 10 to 17% can be obtained.

In membrane electrolysers, chlorine gas (Cl2) is produced which is absorbed with caustic soda in the Chlorine Absorption unit, with the consequent production of sodium hypochlorite.

The main application of sodium hypochlorite is the purification of water for human consumption, although it is also used as a bleach for textile fibres or in other sectors for the cleaning and disinfection of swimming pools or environments due to its fungicidal and bactericidal power.

Although its use is increasingly widespread and it is a growing market, its transport and handling involves risks, and its transport is even restricted in some countries. For this reason, local production in electrolysis plants is increasingly preferred.

FAQ ABOUT OUR SODIUM HYPOCHLORITE PRODUCTION PLANTS

All the information in detail

Our specialisation in the production of sodium hypochlorite focuses on the manufacture of a highly effective and stable solution of sodium hypochlorite, with an active chlorine concentration above 14% between 12% and 15%. This process is achieved by the carefully controlled reaction of chlorine with an aqueous sodium hydroxide solution, ensuring a richness expressed in active chlorine by volume that guarantees maximum disinfectant efficacy. The resulting solution is slightly alkaline (pH 12.0-13.0), which contributes to its potency and stability, although it is important to note that the product is unstable over time and temperature increases, requiring careful handling and storage to preserve its efficacy.

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. The adoption of safety measures recommended in the safety data sheet when handling the product is essential to protect operators and the environment.

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 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.

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, working 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.
