When it comes to chemical water treatment, salt electrolysis provides an appropriate response to the disinfection needs that arise throughout the industrial cycle. Produced on site and on demand, the resulting disinfectant solution reduces the company's carbon footprint, which is a key requirement at a time when manufacturers are making ecological choices.

 

Electrolytic disinfection: from salt to a disinfectant solution on demand

Maintaining water safety throughout the industrial cycle generally involves several successive purification processes. Microbiological control of water is based on methods and technologies that can be adapted according to the type of water entering the industrial cycle (drinking water, surface water, groundwater) and the result expected at each stage of the process. In addition to the so-called physical treatments involving the use of filtering membranes (microfiltration, ultrafiltration) and ultraviolet radiation, the microbiological control of industrial water also relies on chemical treatments.

Electrolytic disinfection has been a recognised technological and ecological solution for several years now. Using mineral-free water, salt and electricity, electrolysis produces a disinfectant solution similar to natural chlorine, a genuine alternative to traditional chemical solutions such as chlorine, ozone and chlorine dioxide. Free from chlorates, which are potential endocrine disruptors, the chlorinated disinfectant solution produced by electrolysis is not classified as harmful to health or the environment. It helps to control Legionella in cooling tower circuits, guarantee the microbiological quality of process water and reduce the effects of corrosion by using fewer chemicals.

Microbiological control at every stage of the industrial cycle

Whether it's "ingredient water" blended with other raw materials in the food industry, "process water" dedicated to industrial operations, or recycled water, the quality and chemical properties of water (presence of organisms and agents in suspension, metals and pesticides in various concentrations, etc.) are subject to various risks of alteration. These include biofouling, the transmission of pathogenic germs (viruses in particular) and the scaling of industrial installations, the impact of which varies according to the purpose of use and the industrial sectors concerned.

Opting for the most appropriate solution will therefore be based on a specific disinfection need, which is all the more complex because it responds to a multitude of situations. These vary according to the nature of the finished products, the types of water use, the effectiveness required, the production stage involved and the risks to equipment, users and neighbouring populations. In the agri-food industry, for example, drinking water must retain its microbiological quality while eliminating the taste and smell of chlorine, while the dairy industry may allow a chlorine residual in its products.

Water treatment: moving towards sustainable and responsible “green chemistry”

The microbiological control of water in industry is a twofold challenge: not only will the health of people and consumers depend on it, but also the performance of production sites. Developed on site and on demand, the salt electrolysis solution reduces the carbon footprint by eliminating the supply chain of heavy and dangerous chemicals, thereby helping to cut operating costs.

Faced with the eco-environmental requirements that are now guiding the strategic choices of manufacturers, the chlorinated disinfectant solution obtained by salt electrolysis paves the way to a sustainable and responsible “green chemistry”. Even if the future lies in the ability to take advantage of different treatment techniques which, when combined, strike the right balance between efficiency, cost and the environment.
